| (papio) - cynocephalus - yellow, anubis -
olive, ursinis - chacma, papio Guinea, hamadryas - hamadryas - babies every
2 years - eat fruit, seeds, young grass, insects, corms, small mammals,
new leaves, rhyzomes - dig holes for water - males tolerant of black infants,
less so of juveniles - mounting is social as well as sexual. |
 |
| some things are not genetically based - relationships
of animals to environment and other animals - isolated mothers don't raise
young successfully - use deductive reasoning - observe behaviour, don't
impute intelligence. |
| seeing with two eyes that have an overlapping field of
view. This is essential to stereoscopic vision. |
| Walking and running upright on two feet. Humans are the
only fully bipedal primates today. |
| eat mature leaves - spend much of day feeding
- small multi-multi groups - long periods resting while digesting - small
ranges, leaves are abundant groom each other's long coats, although difficult
with short thumbs - not very proximal - semi-brachiators. |
| female slightly larger than male - mainly arboreal -
small multi-multi groups - scent marking - females tend to assert themselves
against males. |
| quadrupedal movement - troops about 20, 1
male - cheek pouches less alloparenting - bouncing form of locomotion characteristic
of young - most males leave their natal troop - social play among adults
too - less grooming, but peaceful relations. |
| (pygmy chimpanzees) - bipedalism widely practiced
- sleep in nests - large multi-multi groups fission-fusion societies - females
live natal groups - competition and aggression rare - males may take part
in child rearing - food sharing occurs, mostly between females broad sexual
repertoire - sociosexual behaviour - juveniles and infants also engage in
sex - maintain social bonds with all members of group. |
| (galaginae) - mainly arboreal, nocturnal
- small - eat insects, flowers - nest alone or in small groups - scent marking,
urine washing - seasonal breeding. |
| Animals that travel through the trees by
swinging under branches with a hand over hand motion (using arms to swing
from tree limb to tree limb). The smaller apes and some New World monkeys
brachiate. Gibbons are brachiators extraordinaire. |
