Chimpanzees are highly promiscuous. Females exhibit sexual swellings lasting 6-18 days during which time they attempt to mate with most or all the males of the community. Likewise, males generally attempt to mate with all swollen females. • consortship mating- one on one • Extragroup mating-mating with members of other communities
What kind of groups do chimps live?
Chimpanzees live in permanent social groups called communities, which consist of up to 200 individuals (median 46.3) including multiple breeding females and their offspring, and multiple adult males.
What is significant about chimp warfare?
Chimpanzees on patrol Relationship with other communities Coalitionary Aggression Males form social bonds with other adult males and together patrol and defend the community range against members of other communities. Intercommunity encounters are often aggressive and sometimes involve lethal attacks, especially in cases where the males on one side strongly outnumber their opponents. Males kill other adult males, infants and occasionally adult females. Such killing can result in expansion of the community range.
What is typical of chimp reproduction?
-Slow rates of reproduction -No paternal care -Need long term access to resources Humans, Chimps and Hominids • Humans live longer, are larger, mature more slowly, and begin reproduction later than chimps. • Understood as the consequence of radically different mortality rates. • Mammals: 0.14 - 0.2 per year • Chimps: 0.07 - 0.1 per year • Humans: 0.01 - 0.015 per year
What is the popular problem with race?
"Race," as it is used in everyday discourse, refers to a social category, rather than a biological category. Fundamental Problems with Race • The so-called three great races (white, black, and yellow) are more a reflection of European colonialist politics than an accurate representation of human biological diversity. • Even skin color-based race models that include more than three categories do not accurately represent the wide range of skin color diversity among human populations.
What is culture?
"The set of learned behaviors and ideas (including beliefs, attitudes, values, and ideas ) that are characteristic of particular society or other social group." pg 224 • People share culture behaviors and ideas because they communicate with and observe each other... Culture is a real, materially based, biological phenomenon that is best understood using scientific methods and an evolutionary perspective.

Appear around 160,000 years ago in Africa. First well dated specimens are from 90,000 years ago at Qafzeh in Israel. The Cro-Magnons were found in Europe 25,00 years ago. They were once thought to be the earliest specimens of modern looking humans. First AMHS used Mousterian tools and similar subsistence to Neanderthal. Some were Neanderthal hybrids. Neanderthals can be dated before and after the appearance of AMHS in Israel.

Egalitarian societies are those in which decision-making and power are NOT centralized • Decision-making is a GROUP activity and depends on CONSENSUS • In egalitarian societies, the principle means of organizing society and defining each person's place in society is through MARRIAGE and KINSHIP • Also establish non-kinship friendship bonds.
What are some reasons natural selection might have favored bipedalism vs. quadrapedalism?
Erect posture allows hominids to see over tall grasses of savanna. Bipedal locomotion frees the hands for: Carrying food to central place Making and using simple tools (before tools though) Carrying dependent infants More energetically efficient than quadrupedalism especially for covering longer distances. Erect posture allows hominids to keep cool.

Chimps can be a part of fission-fusion groups called parties. What makes a party and how are they created?
Members associate in temporary subgroups(parties),whose composition may last from minutes to days, and individuals can spend some time alone. Communities are distinct social units,all the members are rarely,if ever, observed together in one group. Party size is strongly influenced • the distribution and abundance of food. • the presence of sexually receptive females & predation risk from leopards Parties are larger in border areas where intergroup encounters are more likely

They were hunters with a meat based diet. There is evidence in this period that they used spears or weapons with a sharp end attached to a sort of handle. They ate large game like buffalo, horses, mammoths, rhinos and deer. Some European sites suggest fishing. Some African sites suggest they consumed shellfish. They used local materials and there is no evidence of trading. Decoration did not exist at this time.

How did this revolution affect subsistence and social organization?
improved technology allowed them to cope better with the environment than previously: - higher population densities - longer lifespan: maybe up to 60 years old rather than 40 - less serious injury or disease than Neanderthals Possibly beginning of ethnic differentiation • Probably kin-based organized bands similar to modern foragers? - bigger, longer term sites - ornaments and ritual burial, maybe more complex social organization - complexity of sites -- including multiple hearths
What is race, biologically speaking?
is a geographically isolated subdivision of a species that can reproduce with individuals from other subspecies of the same species, but does not because of its geographic isolation. - Human populations vary biologically, but there are no sharp breaks between populations. - Human biological variation is distributed gradually between populations along clines.

Bonobo communities are more egalitarian. The strongest social bonds are those among females, although females also bond with males. The status of a male depends on the position of his mother, to whom he remains closely bonded for her entire life.
How are bonobo chimpanzees different from others?
Bonobos can be distinguished from chimpanzees by their more slender frame, longer hind limbs, shorter clavicle, and smaller molars. Bonobos are generally smaller and more slender than chimpanzee and are also less dimorphic-- males only 30% heavier.
What the humero-femoral index of Lucy indicate?
Comparing the length of the arm to the length of the leg (the humero-femoral index) indicates that Lucy had relatively longer arms than most later hominids and definitely longer than modern humans.

How are neanderthals possibly related to humans?
In 1997, German and US scientists used mitochondrial DNA to compare neanderthal and humans. They found that between humans and neanderthals there were 25 differences in the DNA- more than 3 times the amount between modern humans. Other tests using nuclear DNA showed that Neanderthals and humans had several genes that were previously thought to have only been found in humans, like red hair and fair skin. Some significant differences were found as well lie the presence of microcephaline, which is associated with modern human brain development.
What are social bonds like in common chimp communities?
In chimpanzee groups, the strongest bonds are established between the males in order to hunt and to protect their shared territory. The females live in overlapping home ranges within this territory but are not strongly bonded to other females or to any one male.

Widening and thickening of the ilium indicates large abductors. Humans have these large abductors
How are chimps typically dispersed as per chimp dominance hierarchies?
Male philopatry-males remain at their birth group. Female dispersal-females leave to find another group once of age. Creates close ties between males. Also creates intra-sexual coalition competition: Chimpanzees are especially well- known for forming male coalitions to challenge and support other males for dominance within the group.
How did people migrate to the America's in the Upper Paleolithic period?
Migrations took place sometime after the emergence of homo sapiens. 14,000 years ago. Migrated over a land bridge between Alaska and Russia. By 11,000 years ago, there were many people living in North and South America.
What is domestication?
Modification or adaptation of plants and animals for use by humans. When people plant crops, we refer to the process as cultivation. It is only when the crops cultivated and the animals raised have been modified-are different from wild varieties-that we speak of plant and animal domestication.

Neanderthals. May not have lived in caves throughout the entire year, but at least at some points.
Why did food production develop? Or what are the theories?
Most archaeologists believe that certain conditions must have pushed people to switch from collecting to producing food. Hunting and gathering actually takes less time and effort than food production.i.e. soil has to be worked, crops planted, pests controlled, harvest, processed. Agriculture is also risky-could have crops die due to bad weather. Oasis theory of Gordon Childe- 1) Climates dry up (2) People and animals try to find water at oasis (3) People and animals come together to create domestication (4) Agriculture was inevitable Readiness Hypothesis-Robert Braidwood • It just happened... • Suggested that humans became increasingly familiar with plants and animals in their area and began to domesticate them, but does not explain how or why... Kent Flannery suggested that societies will intensify food production only when forced to by population pressure on food resources. • Lou Binford agrees with this and says that demographic stress such as more people moving into an area will require food intensification. • Mark Cohen said that population got so great across the world that no less resources were left.
Does culture have to involve civilization?
NO
Why was this period called the human revolution?
No observable physical change • Significant behavioral changes • Maybe a mainly cultural change like agricultural revolution or industrial revolution? • Maybe genetic changes?: - Language?

Nursery parties hunting parties War parties Foraging parties Sex parties
What is bipedalism and its importance?
Of all primates, only hominins walk erect on two feet. Bipedalism is locomotion in which an animals walks on its two hind legs. A dish shaped pelvis, a lumbar curve in the spine, straight lower limbs, and arched, hnonprehensile feet are all related to bipedalism. Hominins are fully bipedal and can carry objects without impairing locomotor efficiency.

How did homo erectus become homo sapien?
Scientists argue whether homo heidelbergensis or homo antecessor was the transition species. Heidelbergensis was named after a jaw found in Germany in 1907. Other members of this species have been found in Asia, Africa (Zambia) and other parts of Europe. Homo antecessor refers to a group of homing fossils found in the Atapuerca regionn of Spain that appear to be transitional between Neanderthals and modern humans. Closely related to Homo heidelbergensis and many scholars believe they are the same species.

What is the multi regional model?
Suggested that modern humans evolved in various parts of the Old World after Homo erectus spread out of Africa. Hominid population are linked by gene flow. AMHS evolved as a single species from h erectus through archaics into h. sapiens. Modern humans in each region resemble the archaics. Suggested by M. Wolpoff.
What is the Replacement model or the single origin theory?
Suggests that modern humans emerged in just one part of the Old World and then spread to other parts, replacing Neanderthals, Denisovians and perhaps other hominid species. Africa is the place of modern human origin. Spread 200,000-100,000 years ago in Africa and replaced the Archaics. Genetically isolated hominid species and claims there are no genes from Archaics and Neanderthals.
What species can be made out of the habilis?
The amount of variation present in the habilis specimens was more than 3X as great as the amount of variation found in modern humans or in living chimpanzee or gorilla populations. Analysis indicated that the habilis samples could be divided into at least species: H. habilis H. rudolfensis
What is cultivation?
The planting, tending, improving or harvesting of crops of plants and the preparation of ground to promote their growth.
What is the neolithic revolution?
The shift to the cultivation and domestication of plants and animals.
What is Austropithicus Africanus?
The species is restricted to south African sites of Taung, Sterkfontein, Makapansgat. Date: 3 mya - 2.3mya This was the first australopithecine ever discovered - Raymond Dart in 1924. Very similar to A. afarensis
What is the phylogenetic relationship between humans and chimps?
They are both great apes. Great apes are in this order: Chimps, Humans, Gorillas, and Orangutans.
How is information obtained?
Through genetics or through learning (individual and social)
Why was culture used and what does this have to do with cognitive capacity?
To handle environmental challenges, evolving humans developed new tools, clothes, shelter, use of fire, etc., rather than rely on biological adaptation. • Culture can be spread far faster than genes • Cognitive capacity: a concept that includes intelligence, educability, concept formation, self-evaluation, attention span, sensitivity in discrimination, and creativity
Why does erectus have a large brain?
Tool Making Culture Language Sociality
What was upper paleolithic Europe like?
Tool kit has blades, burins, bone and antler tools and microliths. People were mainly hunters, gatherers and fishers who lived in mobile bands. Camps in open spaces or in caves and rock shelters. Evidence of trade, emergence of art, population growth and new inventions like bow and arrow, atlatl, and the harpoon.
What is significant about hominid archaeology?
Tools first arise around 2.4mya • Often found in association with bone • E.g., Bed I in Olduvai, 10-20m, Mary Leakey, 2-1.5mya • Fossilized animal bone • Stone tools, cores, flakes, hammerstones (presumed manuports
Did hominins hunt or scavenge?
Tools found in association with bone • Not deposited by water - sediments do not indicate deposition by moving water • Not death of large number of animals - not a single species; rather a jumble • Some of the bones were obviously process by tools, not non-human carnivores • Besides, how did the stones get there?Locations of cut marks indicated hominids hunted and scavenged. • Predators have first access to carcass and take away the long-bones with most meat. • Scavengers have secondary access and get the leftovers - like the vertebrate and skull •Cut marks are common on both types • Cut marks over teeth marks and vice versa Meat eating •Very few non-human primate captures or eats meat regularly • No primates hunts large game • Human foragers are hunters who hunt and eat the largest big game. •Inuit - Nearly 100% of calories
What is tradition?
Tradition is a strategy of doing things the way they have always been done. • ... little trial and error involved. • Ethnographically: "I don't know...We always do it that way..." • Little diversity
How have monkeys changed over the years?
Transitional (basal) forms older than 6my. Hominins first appear in the fossil record around-5mya. They different from the other Miocene apes in their locomotion (they are bipedal) By 2-4 mya the lineage diversified into three groups: Australopithecines- Gracile and Robust forms East African and South African Homo-big brains, tools and meat (2.3my) Common Ancestor Chart * See slides.
Where do chimps live?
Western and Central Africa. Bonobo species live almost exclusively in the Democratic Republic of the Congo. The greatest number of chimpanzees is located in the rain forests, in what used to be the equatorial forest belt. They can also be found in secondary regrowth forests, open woodlands, bamboo forests, swamp forests and even open savanna where there are forested areas. In savanna areas, they rarely venture far into the savanna except to move from one forest patch to the next.
What is the levallois technique?
When toolmakers produced flake tools of a predetermined size instead of simply chipping flakes away from the core (or nodule) at random. They first shaped the core and prepared a striking platform at one end. Flakes of predetermined and standard sizes could then by knocked off.
What is white supremacy?
White supremacy or white supremacism is a racist ideology based upon the belief that white people are superior to people of other races and that therefore white people should be dominant over other races.
Did the neanderthals go extinct ?
Yes, sort of. Some scientific evidence suggests that some of us are 2% Neanderthals, maybe more.
Did hominins eat meat?
Yes; Ate small and large animals, but mostly the young of large animals like stags, elephants, boars, rhinos and wild oxen.
Is Culture biological?
Yes; Contrasts with genetics, is a separate inheritance system, involves mental phenomena, rooted in neurobiology.
Do animals have culture? If so, is it different?
Yes; For example: the macaque food washing experiment led in the 1950's that continues with subjects today. Also grooming behaviors. Animal culture is not cumulative (things individuals could learn on their own) and is not symbolic.
Was the H. Erectus geographically diverse?
Yes; It traveled through Africa, Asia, the Middle East and Europe. Maybe more than 1 species?
Did bipedalism or increased cranial capacity come first?
Yes; Today, the evidence undoubtedly demonstrates that bipedalism was one of the first hallmarks of the hominin lineage, and may have led to many more advances. For example, one advantage of bipedalism is that the hands are freed, which allowed for the production of more technologically advanced stone tools. In turn, the production of more complex tools may have led to a higher protein diet that affected brain size.
What was Sul Ross' involvement with the confederacy?
Youngest confederate general. 1864 Battle of Yazoo, Ross' policy- no black prisoners
What is husbandry?
the care, cultivation, and breeding of crops and animals.
