an organ found in all female mammals that produces milk for mothers to nurse their young; one of mammalian traits; "mamm" in mammal refers to it
a type of mammal where the baby is forced from the inside of the mother and finishes developing in a pouch (e.g. wombats, kangaroos, koalas)
a type of mammal where the baby develops from a placenta inside a mother (e.g. rodents, carnivores, ungulates, cetaceans, primates)
old world monkeys, new world monkeys
two types of monkeys that were split up after Pangaea broke apart; each evolved differently in separate environments
old world monkeys
in Africa; don't have tails because after climate change, there were no longer trees in Africa
arms and legs, large, complex brain, flatter face, reduced reproductive rate
evolutionary advancements shared by primates
arms and legs
one of evolutionary advancements shared by primates; ball and socket joints improve movement/versatility; the fact that the 5th digit is opposable improves grasping abilities
large, complex brain
one of evolutionary advancements shared by primates; humans have the biggest one within the primates; enables primates to do more things
one of evolutionary advancements shared by primates; shows smell is less important; gives us greater field of view (binocular field) since eyes are in front
reduced reproductive rate
one of evolutionary advancements shared by primates; nature over reproduces because most won't make it; mammals don't because they care for their young
evolution of primates
described by the tree-like shrew of 65 mya giving way to promisians and anthropoids
category including humans and all extinct forms of man (i.e. Austropithecines, early form of Homo, Neandertals, Cro-Magnon, and Modern man)
larger cranial capacity, s-shaped spine vs. c-shaped spine, bowl pelvis vs. flat-long pelvis, aligned toes with arch vs. opposable toes with flat foot, smaller jaws vs. larger jaws, bipedalism vs. quadrupedalism
differences between homonids and great apes
literally handy man; have found sharpened stones with fossils that were probably used for tools (1st to use tools)
literally upright man; first to travel out of Africa; must have had some kind of weapon for protection; carbon remains near fossils suggests they must have had the knowledge of fire
one of homo individuals; fossils found in Germany; hairy; over-sized features; had bigger brains than what we have today but didn't know how to use them
literally wise men; smaller brain than homo neanderthalensis but more potential of using it
earliest homo sapiens; most likely co-existed with homo neanderthalensis before eradicating them through warfare
smarter than competition, suited to environment, luck
three reasons why current humans have not become extinct
