Document Summary
Prework: how is darwin"s theory of evolution differed from that proposed by lamarck. Catastrophism: each layer of fossils represented the remains of organisms that had died in a catastrophe (ie flood) Uniformitarianism: changes in the earth"s crust during geological history have resulted from the action of continuous & uniform processes: difference between relative versus absolute ages of rock formations and the fossils they contain. Relative age: each stratum (sediment layer) is formed at a specific time; so the sequence of fossils from lowest (oldest) to highest (newest) strata reveals their relative ages. Mass left = original mass(1/2)^(time passed/half life: why most living things never form fossils. Decompose before covered in sediment/are preserved in a certain way. Chapter 17, sections 17. 1, 17. 2, 17. 3, 17. 4, purple pages f10 (section on use of. Most is adaptive evolutionary change: evolution occurs in pop, not in individuals. Pops change, but individuals don"t adjust in response to selection: descent: homologies show common ancestry (structural, developmental, molecular)
