-Comparing children to chimps and orangutans -Humans have many cognitive skills not possessed by their nearest primate relatives. The cultural intelligence hypothesis argues that this is mainly due to a species-specific set of social-cognitive skills, emerging early in ontogeny, for participating and exchanging knowledge in cultural groups. -We tested this hypothesis by giving a comprehensive battery of cognitive tests to large numbers of two of humans' closest primate relatives, chimpanzees and orangutans, as well as to 2.5-year-old human children before literacy and schooling. -Supporting the cultural intelligence hypothesis .......children and chimpanzees had very similar cognitive skills for dealing with the physical world but that the children had more sophisticated cognitive skills than either of the ape species for dealing with the social world.

Who is a relative? -May trace descent through the _________ (cf. alloprimates) or __________ or _______. -The rules for tracing descent vary across cultures but there are always rules

Tai

_____ forest shows greater variety of cultural behavior than any other study site

Jablonski; Chaplin Light; Dark light skin cooling folate; dark Africa

______________ N.G. & ____________, G. 2000 The evolution of human skin coloration Journal of Human Evolution ______ (australopiths) -> ______ (Homo sp.) -> 6 M years ago: After the split from chimpanzees early hominin ancestors probably retained the long hair and _____________ we still see in modern chimpanzees 4 ½ -2 M years ago: hominins move onto the savannah -Dissipate heat through evaporative ___________ (sweat glands increase, hair is no longer protective) -Excessive sun on hairless skin -> loss of ________ (birth defects) evolution of ______ skin color to prevent folate photolysis (avoid neural tube defects such as spina bifida and anencephaly) *In notes section of PP:* Light skin color with fur followed by loss of fur (apparent "hairlessness" and sweat glands) 2 Mya to present: multiple hominin migrations out of ______ begin....only the last migration was Homo sapiens (perhaps as recently as 60 kya?) Less than 40,000 years ago: anatomically modern Homo sapiens arrives at latitudes above 50 degrees...in areas of low UVB radiation light skin color may have re-emerged to ensure adequate Vitamin D synthesis... Human populations that moved from low latitudes to high latitudes multiple times may have alternating periods of dark and light skin pigmentation

Foraging 99%

______________-how humans survived for ____% of human existence WT-15,000 "Nariokotome boy" 1.6 Mya Lake Turkana, Kenya - forager Homo lineage began with a dietary shift Substantially larger brain (900 cc) (energetically expensive) Short gut means less transit time for food & implies a nutrient-rich diet...cut marks on fossil animals bones suggest meat Modern body proportions (long legs) suggest long distance travel on the ground (perhaps running down prey animals)

Marriage not

________________- an exclusive and permanent bond between individuals (most often between at least one man and at least one woman) which is governed by culture-specific rules Non-human animals do _____ have marriage

Adaptive strategies

_________________ - system of economic production (patterns of subsistence)

Ultrasociality

______________—enhanced flow of information

Mammals; mammals

_____________— most ___________ do not live in groups but those that do are marked by spatial proximity, social interaction, individual recognition & xenophobia Old World monkeys (Last Common Ancestor lived 25 Mya) -A single stable group with daily contact among all members -Female-bonded -Female philopatry/ Male emigration Chimpanzees (LCA 6 Mya) -Bi-level society known as "fission-fusion" -Foraging party (composition changes daily) -Community (stable composition; "strangers" are attacked) -Male-bonded community -Male philopatry/Female emigration -Less frequent contact among members of the community who share and defend a territory...recognizing and remembering individuals not seen for weeks or months demonstrates *greater cognitive ability* What about humans groups?
