Remains of past life forms
all genes in a population
Classification using sets of categories
splitting of a population
All living things are adapted and must change over time to survive
Modern human beings as well as primates who walk erect(Bipedal)
4.2-2.3 mya earliest well esablished homid fossil
Small teeth and jaw.. smaller skull
bigger teeth larger jaws more muscular
HOMO 2 species
flatter face, forehead less sloping and larger brains
larger brain smaller teeth
1.8 to 100,000 brain size overlaps range of modern human tools are hand axe and flaking tools used poss of burial and fire
moden humans 300,000 ya-
yet to be rigorously tested
has already undergone extensive testing
any spontaneous change error in genetic code
Archeology, Biological anthropology, cultural anthropology, linguistics
new world monkeys
all arboreal live in trees have prehensile tails
Old world monkeys
Dont have prehensile tails
study of past life using fossils and geological context
distinctive human traits
bipedal, disk shaped pelvis, lumbar spine, straight lower limbs, arched non prehensile feet length and flexiable thumb
process where gene pass from one pop to another through mating and reproduction
genetic differences bet. pop. produced by the fact that genetically diff. ind. est. true pop
large brain, tree dwelling, 3d visionsteroscopic reduced sense of smell grasping feet and hands opposible thumb flexiable limbs, quadripedal, but pipedal for breif periods few offspring extened direct care social animals
genetic drift wright effect
random fluctuation of allels in a population from generation to generation; smaller pop= greater flucuation
