ANTH 1001 : Anth 1001 Test 3 Notes
Document Summary
If conditions are favorable, minerals replace substances in bone and fill in spaces, converting the bone into rock. Source of bias in fossil record (non-randomness in fossil record) Body size of species (larger more robust bones more likely to be fossilized than smaller bones) Where fossilization occurs (no fossil record of gorillas) exposure and discovery of fossils. Earth"s outer shell (crust and part of mantle) is divided into major plates and minor plates. Movement of plates influences migration routes, climate and ecology. North america and europe were connected during paleocene and eocene. Africa was an island continent prior to 19 mya. Madagascar was an island before the emergence of primates. Theory that lemurs colonized madagascar by crossing the mozambique channel on floating masses of vegetation. Sa was an island before the emergence of primates and the panama connected north and south america less than 5 mya. Theory is that the ancestor of nw monkeys colonized south america by crossing either.
