INTRODUCTION
Main processes involved in peopling the world
Eternity. High up in the North in the land called Svithjod, there stands a rock. It is a hundred miles high and a hundred miles wide. Once every thousand years a little bird comes to this rock to sharpen its beak. When the rock is worn away, then a single day of eternity will have gone by." (Hendrick Van Loon in The Story of Mankind). |
- Genesus--evolved in southern Africa; Great apes; closely related to Gorillas and chimpanzees Genetic distances: gorillas to humans=1.4%; Humans to chimpanzees=1.2%; chimpanzees to gorillas=1.2%; also fossil records trace origin to Africa.
- Spread--movement out of Africa via land bridges initially and gateways; later with boats/ships etc.
- Isolation--geographic isolating mechanisms include mountains, oceans, deserts, jungles, distance.
- Differentiation--adaptation, evolution, founder effects, bottlenecks, drift all contribute to morphological and behavioral changes in any biological population; later with humans have biocultural mechanisms of isolation.
- Evolution--any genetic change in organisms from generation to generation.
- Adaptation--any structure, physiological process, or behavioral pattern that makes an organism more fit to survive and to reproduce in comparison with other members of the same species. The evolutionary process leads to the formation of such a trait.
Three Necessary and Sufficient Conditions for Evolution:
- Heritability--parent to offspring transmission of genes
- Variability--differences in traits within population
- Selection--relationship between survival and/or reproduction and trait; only "fittest" survive.
Factors affecting genetic change in populations:
Evolutionary Constraint: Promises
"I never could keep a promise. I do not blame myself for this weakness, because the fault must lie in my physical organization. It is likely that such a liberal amount of space was given to the organ which enables me to make promises that the organ which should enable me to keep them was crowded out." quotation from Chpt. 23 in The Innocents Abroad by Mark Twain (1869). |
- Selection: (i)natural selectionThe differential contribution of offspring to the next generation by individuals of different genetic types but belonging to the same population. The differentials may be due to differences in reproduction or survival; (ii)sexual selectionthe differential ability of individuals of different genetic types to acquire mates. One-of-two types of sexual selection: i)female choice (eg. the female pea hen consorts with the peacock which has most attractive tail); or ii)male-male competition (eg. elephant seal bulls fight each other for access to females and create a harem); and (iii)kin selectionthe selection of genes due to one or more individuals favoring or disfavoring the survival and reproduction of relatives (other than offspring) who possess the same genes by common descent.
- Bottleneck--drastic decrease in numbers of individuals of a population usually resulting in a reduction of genetic variability. An example of a bottleneck is when a famine drastically reduces a population size. The surviving members of the population will possess traits that helped them survive the famine such as an ability to carry greater body fat or the ability to out-compete others searching for scarce food. These traits will thus be more widespread in subsequent generations since the genetic stock of those not possessing those traits was eliminated due to the famine.
- Founder Effect--extreme case of genetic drift; occurs when small number of indivuduals colonize an area and thus have small amount of genetic variability.
- Drift--random changes in traits with time.
Fundamental Biological Traits in Humans
- Tropical origin. The great apes evolved in tropical East Africa. This is important because there is no distinct breeding season.
- Bipedalism. Although some primates are capable of walking on two legs, humans are the only primate and one of the very few mammals (e.g. kangaroos) is truly bipedal. As Richard Leakey notes: The origin of bipedal locomotion is so significant an adaptation that we are justified in calling all species of bipedal ape "human." This is not to say that the first bipedal ape species possessed a degree of technology, increased intellect, or any of the cultural attributes of humanity. It didn't. My point is that the adoption of bipedalism was so loaded with evolutionary potentialallowing the upper limbs to be free to become manipulative implements one daythat its importance should be recognized in our nomenclatures. These humans were not like us, but without the bipedal adaptation they couldn't have become like us. The "triple pack"bipedalism, large brain, and tools, did not arrive simultaneously. Theories on bipedalism: (i)carryingweapons, tools, food, infants; (ii)travelling between food trees; (iii)feeding from bushes; (iv)feeding on grass seeds; (v)provisioning family (see Shreeve 1996).
- Large brains. Tthis aspect sets humans apart from other animals including other primates. There are constraints on the size of the head in newborn infants due to the pelvis size in women. The brain allows for information transfer between generations. Thus natural selection favored mechanisms that keep children in contact with the parents for a long time (learning). Neotony has resulted; the prolongation of childhood and postponement of sexual maturation (puberty). Human brain size suggests a group size of about 150 individuals; the number appears to be the fundamental unit of group cohesion. Gibbons w/small brain live in groups of 4-6; chimps with larger brain live in groups of 50-80.
- Language. Although many species have evolved sophisticated mechanisms for communicating, humans are the only animals with a true language.
- Birth spacing. Births needed to be about four years apart so that mother could carry only one infant. Lactation also prolonged; low energy content of human milk so that infants suckle long and often. This also keeps infant in contact with the mother.
- Mating strategy. Female can benefit from male food gathering/hunting so males play a strong role in their lives beyond mating; based on sexual dimorphism (size, facial hair, etc.) polygyny (more than one female per male) appears to be evolved behavioral trait; human females are the only mammal which is a covert ovulator (not even she knows); also female humans are the only mammal whose mammaries (breasts) enlarge prior to the first pregnancy. Implies is a secondary sexual trait and not just used for infant nourishment; Also male semen volume and sperm density suggests that humans are adapted for a low level of sexual activity (e.g. relative to chimpanzees).
- Menopause. Humans are one of only a small number of species that exhibit a post-reproductive period. Has been argued that this period evolved for "grandmothering".
Evolution of Modern Man
Australopithecus
- Australopithecus afarensis (Gracile). First hominid; lived 4 million yrs ago; called 'Southern ape of Afar' from sites in Ethiopia's northern Afar Triangle; looked like a small upright chimpanzee; bipedal; thought to have given rise to other australopithcines and to our genus, Homo; 'Lucy's skeleton (3 million yrs old) is the oldest known for any hominid; large differences between the bodies of males (4 ft, 10 in; 143 lbs) and females (3 ft. 3 in; 66 lbs);; suggests a nonhuman, nonmonogamous social structure with harems like gorillas;
- A. africanus (Gracile). Southern ape of Africa; lived from 1 to 3 million yrs ago; believed to have evolved from afarensis; height 3-4 ft; weight 45-90 lb; tooth and jaw design suggest this ape-man chewed plant foods but also might have scavenged meat; use of tools is disputed; most fossils come from Sterkfontein Cave in South Africa; also lived in Kenya, Ethiopia, and Tanzania.
- A. robustus (Robust). 'Robust southern ape'; larger and more strong built than africanus; height 4 ft 11 in - 5 ft 7 in; weight 110-154 lb; lived approximately 2.5 million yrs ago; all fossil finds come from South African caves; apparently died out about 1.5 million yrs ago; massive cheek teeth and small front teeth show that robustus was a herbivore; brain capacity 500cc; brain capacity of modern man is 1400cc.
- A. boisei (Robust). Largest, burliest australopith; lived between 1.0 and 2.5 million yrs ago in east Africa; believed to have evolved from robustus; height 5 ft 3 in - 5 ft 10 in; weight 132-176 lb; large skull, with brow ridges; apparently chewed large quantities of leaves; may have made or used stone tools; brain capacity 500cc.
Homo
Homo habilis. Called the 'handy man'; approximately 1.8 million yrs old; may have evolved from either Australopithecus afarensis or africanus discovered by Louis and Mary Leakey in Olduvai Gorge; height 4-5 ft; weight about 110 lbs; bigger brain than Australopithecus but a smaller, less projecting face; relatively smaller cheek teeth but larger front teeth; arms shorter in relation to legs, and hip bones permit both bipedal walking and giving birth to babies with large heads.
Homo erectus Upright man; lived between 200,000 and 1.6 million yrs ago; evolved in Africa and spread to Europe, East Asia (including Peking man), and Southeast Asia (Java Man or Pithecanthropus); 200,000 yrs ago it was probably extinct, perhaps the victim of competition with its own descendents.
Homo sapiens neanderthalensis. Evolved from an archaic form of Homo sapiens around 200,000 yrs ago, and who lived to about 35,000 yrs ago. lived mostly in and about Europe; classic Neandertals were short, extremely muscular, and stocky, with large joints and hands; height about 5 ft 7 in; weight about 154 lb; appearance coincided with the Middle Paleolithic; cold adapted
Homo sapiens sapiens. Populations 40,000 yrs ago were living in Africa, Asia, and Europe that did not differ greatly in appearance from modern humans; collectively, they are known as Upper Paleolithic peoples, and include the Cro-Magnons of Europe; greater diversity of tool making evident including the use of chisel-like tools.
Most paleoanthropologists believe anatomically modern human beings evolved in Africa more than 100,000 years ago. However, until a recent finding in sub-Saharan Africa it was widely believed that the behavior of modern humans arose 40,000 years ago in Europe where humans were first able to make innovative tools, plan for the future and express themselves symbolically. This finding by a team of archeologists working in Zaire, discovered evidence of sophisticated behavior in sub-Saharan Africa perhaps 90,000 years ago. The evidence was in the form of tools with modern appearances including a carved bone harpoon tip with serrated edges. If the dates turn out to be correct, the findings will have profound implications for the evolution of human behavior (1995 Science, 268, 495).
New View of Human Evolution. Although most anthropologists believe that the human race originated in Africa, new measurements open the possibility that although its prehuman ancestors began in Africa, different variants of the primate genus Homo may have independently evolved in Africa, Europe and Asia. Until now, the oldest human remains in Asia were believed to be about 1 million years old. By comparison, the oldest human remains in Africa were estimated at about 1.8 million years old. Many anthropolocists believed that the age difference between the earliest African and earliest Asian Homo erectus fossils implied that the species got its start in Africa and then radiated much later to other continents. However, this theory has troubled some scientists. For example, Homo erectus in Africa devised what is known as the Acheulean tool kit, frequently found at sites in Africa but not in Asia. If Homo erectus developed in Africa, invented these useful tools and then set out to colonize Asia, why not take their tools along? If, on the other hand, separate branches of the Homo erectus tree evolved simultaneously in Africa and Asia, this problem would be explained: the founders of the Asian branch left home before their African cousins had invented Acheulean tools. This view is strengthened by the recent finding that skull fragments of Homo erectus found some time ago on the Indonesian island of Java are up to 1.8 million years old--as old as the oldest Homo erectus fossils ever found in Africa (Sacramento Bee, February 24, 1994).

Evolution of farming
Note that Africa and Americas are north-south whereas Eurasia is east-west. Thus plants and animals can spread along axes where climates similar. Farming is not an invention or a discovery but rather the result of evolution. Hunter-gatherers pick the largest seeds and bring them back to camp. The discards or spilled seeds sprout and begin to grow next to camp. After several generations of this process the plants which produce the largest seeds are growing close the the camp or settlement which has evolved from a hunting camp to a farming commmunity.

Traits for plant domestication:
Edible
high yields in wild
easily grown
grow quickly
stored (not perishable)
self pollinating
Animal Domestication
The importance of domesticated mammals rests on surprisingly few species of big terrestrial herbivores. The "major five" include the following:
- Sheep (Central Asia)
- Goat (West Asia)
- Cow (Eurasia)
- Pig (Eurasia)
- Horse (S. Russia/Mongolia)
The minor species include (note that all are from Eurasia):
- Arabian and Bactrian (2-humped) camels (Arabia and Central Asia)
- Llama (Andes)
- Donkey (N. Africa)
- Reindeer (N. Europe)
- Water buffalo (SE Asia)
- Yak (Himilayas/Tibet)
Necessary and Sufficient Conditions for Domestication
- Dietherbivores convert plants to meat; 10% conversion rate. 10,000 lbs corn to 1,000 lbs of cow; 100,000 lbs corn to 10,000 lbs herbivore to 1,000 lbs of carnivore; not eat dog; also should eat general plants and not specialized plants
- Growth ratemust grow quickly; gorilla and elephants require 15 yrs; cows one year
- Captive breedingelaborate courtships not good
- Dispositiongrizzly bears eat owners; African buffalos nasty; zebras bite and hold on.
- Calm and not panicgazelles and deer hurl themselves into fence
- Social structureowner becomes alpha; lead dogs not cats

Classification. The divisions between blacks, whites, and the other major groups are arbitrary because each group shades into the others. All the human groups on Earth have mated with humans of every other groups they've encountered. Nevertheless, recognizing these major groups and calling them by these inexact names is a shorthand that makes it easier to understand history. By analogy, it is also useful to divide classical music into periods like "baroque," classical," and "romantic," even though each period is diverse and shades into other periods. (J. Diamond "How Africa Became Black" Discover Magazine, February, 1994) |
Asian
- small groups in central Asia developed at end of last Ice Age developed through natural selection
- straight black hair and dark brown eyes
- skin color varies from light to medium brown
- beard and body hair meager
- nose not protrude and because the cheek bones on either side are broad and massive, the face appears flat
- adaptations to extreme cold; Asian fold in eye to protect from hard-driving snow, flatter face to resist frostbite; minimal facial hair since beards tend to ice up in extremely cold weather; cross sections of Asian hair have larger air spaces for insulation
- in most northern groups (Eskimos) more body fat to protect from cold. When Ice Age receded then Asians dispersed and carried their cold-adapted features with them
European
- not just European but part of Asia, India and most of north Africa
- the nose is the most distinctive feature that projects well forward of the eyes
- receding cheek bones produces a facial contour that is strongly contrasted with that of the Mongoloids
- also beard and body hair; skin color ranges from white in northern Europeans light brown is most common but very dark in some Caucasoids in India
- blue eyes better adapted to see in northern regions where dark much of the year
- longer noses help warm inhaled air and thicker body hair in men (these cold-adaptations were different than Asians who were adpated to the hard-driving, needle-like snow central Asia)
- much of Europe is forested winters are much like New England and also temperatures are not as low; sunlight produced paler skins to allow vitamin D synthesis.
Swords, guns, armies and politics. There are three basic life style types: hunter-gatherer, farmer, and nomad. In a farming society with its stored food surpluses and concentrated villages, people have a chance to specialize, to become full-time metal workers, soldiers, Kings and bureaucrats. Hence the farmers, and not the hunter-gatherers or the nomads, are the ones who develop swords and guns, standing armies, and political organizations (J. Diamond, Discover Magazine, Feb. 1994). |
African
- Africa is associated with dark-skinned peoples in same way that Europe associated with Caucasoids
- But sub-Saharan Africans are typical race only of that part of Africa south of Egypt and the Sahara Desert
- dark brown to black skin, tightly curled hair, distinctive facial features with larger teeth and broader nose; darker skin protects from sun; tall and thin stature in desert cultures (Sudanese) help dissipate heat
- brown skin more in forested areas of western Africa; overall have morphological adaptations to high temperature, high levels of solar radiation and high humidity
- tightly coiled hair keeps off neck so facilitates cooling and evaporation.
American
- skin color about same range as Asian
- hair texture about same as Asian
- most notable difference is have prominent noses, more European than Asia
Australians
- skin color darker; often quite black
- hair frequently curly; beard and body hair abundant
- wider noses

- Tend to be brown rather than black
- provided most of blacks to New World; voyage from Europe to coast of Africa across to Brazil, Caribbean and east coast of U.S.
Timbuktu--Fabled City of Africa. Located near the bend of the Niger River in the country of Mali in Northwestern Africa, Timbuktu dates back to prehistory when it was a stop-over for caravans trading in gold, salt and slaves travelling from sub-Saharan Africa such as Benin or the Ivory Coast to points north such as Morocco, Tunis or Tripoli. The savannah meets the desert in this region so the trans-Saharan camel caravans would transfer their cargo to donkey caravans. |
- East African Black
- Horn of Africa
- Includes various subgroups including the Masai;
- consists of lakes and highland tribes and covers Kenya, Uganda, Rwanda, Burundi, Tanzania, Malawi, Zambia and Mozambique
- many agriculturalists but also hunter gatherers, include the Nilotes (due to provenance in Nile region) are cattle-owning people
- Arab influence on coast broach influence of Islam
- Bushmen and Hottentot
- Bushmen are the desert hunters
- short (5 ft), skin yellow brown, wrinkled; broad nose contrast with thin lips, pointed chin
- they are the hunter/gatherers of the Kalahari Desert
- Hottentots are less short (5.5 ft)
- shometimes large buttocks in women
- differ from the Bushmen as are pastorals that herd cattle.
- Forest Pygmy
- The pygmies are short 4 ft. 6 in., people of the forest who live by hunting and gathering
- close to Bushmen blood groups but live in forest
- speak both Sudanic and Bantu languages
- the only people who are not afraid of forest; Some people feel that pygmies are the original and unique population of Africa and that West African
- blacks who surround them are a mixture of very long standing of pygmy and Caucasian
- pygmies and bushmen may be ecological races of single basic stock.
- Sudanese
- Inhabit hot and dry savanna region between forest belt and Sahara desert
- tall, strongly built and black skinned
- curly as distinct from frizzy hair
- Bantu
- descendents of people who emerged from equatorial rain forests of Central Africa
- actually a mixture of Hamitic, nigrillo and Bushmen types
- united by Bantu language.
- South African Black
- called "Cape Coloreds"
- descended from union of Dutch and Huguenot settlers with indigenous Hottentots and to lesser extent the Bantu and Malay
- these rank just below whites in social hierarchy
INDIA
Three major racial divisions:
- Europoid of north and of large parts of peninsular India
- Mongoloid race near Himilayan regions
- Tribal populations in Middle and southern parts dwell in veddoid or proto-australoid
- Vedda represent one of the most archaic sections of humanity; link oldest surviving racial stratum of India with Australian aborigines
- People of some parts of southern India resemble those of European have a dark skin color seen elsewhere only in blacks.
- Vedda
- Semi-nomadic tribe inhabiting forests of highlands of central Sri Lanka
- remnants of primitive racial stratum which extended over pre-historic times all over south and South East Asia
- small in stature with dark brown skin and curly or wavy hair; broad faces, flat noses, deeply set eyes, full lips, weak receding chins
- live in caves use stone implements arrow points, flakes and scrapers; no concept of trapping or fishing except poisoned water
- similar to Ainu of Japan.
- Dravidians
- Spread into India well before Indo-Aryans appeared
- pushed into southern India, major group is the Tamil
- physical features vary from small, dark and black-African looking to tall Aryan-looking
- The Tamil are primarily in Sri Lanka and have a strict caste system from Brahmin to untouchables.
- Hindus
- Hindus are a people first and a religion second
- the word Hindu is primarily a social term; best described by a process of elimination--inhabitant of India, practices Hinduism as religion, must be born a Hindu cannot achieve it (no converts).
- The classical definition is one who adheres to four broad classes or varnas.
- At the top are the Brahmin (learned)
- followed by the Kshatriyas (warrior)
- Traders and merchants
- Laborers, servants and others who have low social status but are still in the system)
- Four stages within each class including student, householder, forest dweller and ascetic.
- Under them all are the outcastes who are outside of the system and therefore are "untouchable". They do the lowliest of jobs such as latrine cleaning
- up to 75% of India's people are Sudras or outcastes
- The Hindus are descended from a variety of races including: aboriginals, Dravidians, Aryans, Mongols and Semites.
PACIFIC REGION
- Almost no link between a certain physical trait and a place of origin; Peru, north-west America, southeast Asia, Japan, India and even China have all been cited as having cultural affinities with Polynesia.
- Apparently no longer disputed that Peruvians sailed and drifted to Easter Island
- most probably route of migration of first Pacific peoples is from Indonesia
- sweet potato is native to South America but is common in Polynesia.
- Melanesian
- Includes Fiji and includes islands northeast of Australia
- darker skinned and heavier than other two broad groups; comes from mixed Papauan and immigrant stocks; southeast New Guinea to Fiji Islands and south to New Calendonia
- short 5 to 5 1/2 ft; heads long, broad noses; skin from dark coffee to light brown; hair frizzy to wavy
- Prevailing wisdom was that Melanesians came from one or two migrations out of Asia within the last 10,000 years
- yet the poeple of the island of Malaita had blond Afros, while the highland people of nearby Bougainville had wiry hair and jet-black skin like West Africans
- however, movements may have been ancient and diverse. A growing body of evidence suggests these islands (The Solomon Islands) could be one of the first, not last, parts of the world to be settled by modern humans (Science, 268, 265, 1995).
Micronesian
- most of Micronesian islands are north of the equator; most are small (micro) coral atoll formations and include the Caroline, Marianna, Marshall and Gilbert islands
- physically heterogeneious and tend to be smaller than the Polynesians who are often massive;
Polynesian
- these islands cover a greater area than other two main Pacific groups
- form triangle from New Zealand to Hawaii to Easter Island
- includes Tahiti, Bali, Bora Bora, Samoa; some are relatively light skinned and almost caucasian features; others (eg. Tahiti) are darker-skinned and mongoloid in appearance
- the island Mas a Tierra is the island of Robinson Crusoe which is about 500 miles west of Chile
- island is about 35 square miles; written by the Scot Alexander Selkirk who lived on island for four years starting in 1704; believed to originate from India by way of Indonesia though evidence that admixture from South America;
- heavy and broad faces with high forehead, large straight nose, full defined lips, rounded jaw-line; black eyes--sometimes with a slanting Mongoloid appearance; wavy hair.
Negrito
- May be one of remnants of Australoid peoples similar to Ainu, Vedda and Aborigines
- Austro-asiatic or Negrito stock which is related to pygmy
- only a few thousand left; the first people to reach this area were migrant peoples of the prehistoric period from the Asian land mass
- the negrito descendants of these aborigine migrants live isolated in the mountains of eastern and western Luzon and in the north-east Mindanao of Phillipines
- hunt small game with bows and arrows and blowpipes.
AUSTRALIA
- Carpentarian
- traditionally hunters/gatherers
- believed to have migrated from India, Malaya and New Guinea via Cape York peninsula
- long narrow skulls, deep set eyes, wide nostils
- hair way to frizzy
- around 100,000 survive
- Tasmania
- Tasmania was joined to mainland until 11,000 years ago but separation forced people to remain in the Stone Age
- average height was 5 ft 4 in
- 1876 the last full-blooded Tasmanian died; when first discovered dubbed "representative of Paleolithic men" and were denied their humanity
- never advanced further than chipping and flaking stone implements
- could not draw, no mythology, canoes were bundles of bark tied together; obtained fire by rubbing sticks rather than "groove" method.
ASIA
- Classic Mongoloid
- Siberia, Mongolia, Korea, and Japan
- Japanese thought to have come to Japan from Korea driving the aboriginal peoples out
- language remains a mystery since close affinities to Polynesian, Turkish and Finnish languages
- Koreans--Chinese cultural influences seeped down from north and distinctive, fairly homogenous Korean national culture developed
- Mongolians--stepps are huge spaces that lie between great mountain chains; Mongolia is vast plateau covering 600,000 square miles with Gobi Desert in south
- Ghenghis Khan in 12th century united hundreds of tribes into one vast empire from Europe to Korea.
- North Chinese
- northern and central China and Manchuria
- China is the heartland of the mongoloid people; thought to have evolved there over a million years ago
- around 94% of the Chinese population are Han peoples; Manchurians are separate group in northern China.
- Southeast Asian
- South China, Thailand, Viet Nam, Burma, Indonesia, Cambodia
- where to draw the line between Southeast Asian and Pacific peoples is not clear cut especially between Indonesia and the Phillipines
- Filipinos are now a distinctive race with an admixture of Chinese, Spanish and American (another mixture) blood
- Indonesians are a mixture of Malay, Melanesian and Papuan with over 300 ethnic groups and 250 languages
- Indonesia includes Bali, Sumatra, west Borneo, Java; the Cambodians are the most australoid-looking people in Southeast Asia while the Burmese are the most mongoloid looking.
- Tibetan

- Lapp
- Arctic Scandinavia and Finland
- reindeer nomads related to Finnish but extremely old culture that has remained isolated
- the Eskimos are more of the sea culture whereas the Lapps are the inland culture
- Lapps are 20 to 50% Siberian and 50 to 80% European (Scandinavian).
AMERICAS
- First humans to reach North America arrived some time between 70,000 and 12,000 years ago
- At the coldest intervals between those dates, sea shrinkage exposed a broad land bridge, Beringia, now drowned beneath the Bering Strait. Hunter gatherers probably walked from Siberia to Alaska. Moving south through one of two ice-free routes, they fanned out across the Great Plains, then penetrated southward.
- Anthropologists believed these were the so-called Paleo-Indians who had straight black hair, coppery skin, dark eyes, broad cheekbones, and shovel shaped incisor teeth.
- Such Mongoloid features occur in American Indians alive today
- there is a "sameness" about the physical appearance of most New World populations--pigmentation, eye color, hair color, hair form, beard and body hair sparse
- May have been a relatively small band that founded all of the Americas starting at the Bering Strait
Domesticating Animals
By around 4000 BC west Eurasia had its "Big Five" domestic livestock--sheep, goats, pigs, cows, and horses (East Asians domesticated four other cattle species--yaks, water buffalo, gaur, and banteng). These animals provided food, power, clothing and military advantage (i.e. horses). Why didn't American Indians reap similar benefits by domesticating the corresponding native American mammal species: mountain sheep, goats, peccaries, bison, and tapirs? Or Australians mount kangaroos to invade Eurasia? The answer is that only a tiny fraction of the world's wild mammal species have been domesticated. There are three crucial characteristics of animals required to domesticate: i)social species so that the herd's subordinate individuals have submissive behavior towards dominant individuals; ii)cannot be nervous such as deer and antelope; and iii)must be able to breed in captivity (from Diamond 1992). |
- North American Indian
- The Indians may have been more like earlier Mongoloids than present day Mongoloids
- main groups include: Blackfoot (Indians of forest in Canada), California Indians, Cherokee (Appalachia), Cheyenne (plains Indians in Dakotas/Wyoming), Chipewyan (Subarctic in Northwest Territories of Canada), Cree (subarctic group), Great Basin Indians, Iroquois Confederation (North-eastern Indians lived in villages along streams/lakes and raised crops of sweet corn, benas, squash), Ojibway (subarctic), Pawnee (Plains Indian in Nebraska etc), Shoshone (Great Basin), Hopi (southwest such as Arizona), Navaho (south west).
- Central American Indian
- At least 90% of people in Central America are mestizos: descendants of unions between Spanish and Indians
- today Indians represent only about 8% of population
- the face of Central American Indian is less flat than that of the east Asian mongoloid
- he has a more prominent nose; and his skin pigmentation is darker; slender inbuild with dark eyes and a noticeable lack of body hair
- stands between 5 ft 2 in and 5 ft 6 in although some groups qualify as pygmies.
- About 3.5 million Indians in Mexico and Central America.
Ethnic Trump. That my son, Luke, goes to Chinese-culture school seems inevitable to most people, even though his father is of Irish descent. For certain ethnicities trump others; Chinese, for example, trumps Irish. This has to do with the relative distance of certain cultures from mainstream American culture, but it also has to do with race. For as we all know, it is not only certain ethnicities that trump others but certain colors: black trumps white, for example, always and forever; a mulatto is not a kind of white person, but a kind of black person. (from Gish Jen, New York Times Magazine, July 7, 1996). |
- South American Indian
- Two massive geographical influences--Amazonian system (lowlands) and Andes (highlands). Portugal took possession of Brazil.
- All European powers had the disadvantage to contend with that in this region there were no united Indian empires there for the taking. Each tribe was an autonomous political unit and each had to be pacified, subjugated or treated separately. Many tribes still practice scalping, head hunting and head-shrinking.
- People of highland tend to be either Spanish, mestizo or Indian (not African).
- mestizos is mix of the fire of the Spaniards and the tenacity and craftmanship of the Andean Indian
- Main Indian settlements in Bolivia, Peru and Ecuador
- at height the Inca Empire stretched from the south of Colombia to central Chile--a distance greater than the width of the entire U.S.
- South American Black
- Cross between Indian, African and Spanish
- range over much of South America; descended from the four million or so slaves who were transported into South America to work on sugar plantations; one of the most striking aspects of the Afro-Brazilian culture are the religious cults, such as macumba; from this African class that Carnaval, the pre-Lenten feast, derives its spontaneity.
- Eskimo
- More like modern Asian than any of the other New World races because they possess blood type B as do present day Asians but this blood type is not present in Indians of Americas
- feel migration only 6,000 years ago; their way of life is to hunt large sea mammals and have seagoing boats for hunting and travel; would not have need Bering Strait bridge to cross over
- Eskimos were part of interior plains up to 300 years ago
- then Cree Indians obtained guns and forced back to northerly fringes; Eskimos not warriors; polar Eskimos most northerly peoples
Black. Despite increasing use of the term African-American, most black Americans still prefer to be called black, according to a survey conducted in 1991 by the Joint Center for Political and Economic Studies, a black-oriented study group. It found 72% said they preferred black. The change from black to African American was first proposed in 1988 at a meeting in Chicago to lay the groundwork for the African-American Summit. Jesse Jackson, New York Mayor David Dinkins and other prominent blacks embraced the change. Blacks with some college education were more likely to favor the new term than those who had not gone beyond high school (Associated Press, Davis Enterprise, January 28, 1991). |
- North American Black
- Slaves were in Haiti as early as 1501
- around 10 million blacks arrived in western hemisphere; 60% in 19th century destined for sugar plantations of Brazil and Caribbean
- majority of slaves bound for North American arrived during span of 70 years from 1741 to 1810
- 1865 abolition of slavery
- first generation to live in freedom in U.S. were 3rd and 4th generation natives of the U.S.; most bound to British North America appear to come from narrow strip of west Africa coast: 50% from Angola and southern Nigeria; 1/8th each from Ghana, Senegal, Gambia and Sierra Leone; some from Benin, Biafra and Mozambique
- during slavery many children were born to black mothers and white fathers. Second generation were 1/4 black and third generation was 1/8 black. Most individuals that were 3/4 or more white ancestry could "pass for white" and thus, could join white community and bestow genes upon it (Brues, 1977). North American blacks are 50% European in the north and 10% European in the south
- blacks will be indistinguishable from whites in 1000 years if rates of inbreeding continued as over last 300 years.
- Latino
- Latin America consists of i)Middle America (Mexico, Caribbean, Central America and Antilles) and ii)South America
- when Spaniard conquered Mexico and Central America in the early 16th Century there were two great civilizations--Aztecs and Maya
- However, for every 10 men who came from Spain there was only one woman. Thus a Spanish/Indian population started including concubines and wives. South America, Central America, Mexico and West Indies are commonly known as Latin America.
- Hispanic derived from Latin Hispanicus. Hispania was the name of the Roman province of the Iberian Peninsula in Lusitania. Thus refers to both Spanish and Portuguese.
