Document Summary

Not all traits are adaptations: bugs weren"t originally made to fly, the wings were original cooling devices, phenotypes are affected by environment, the number of genes doesn"t have anything to do with how complex the organism is. Changes of species over a long period of time. Comes from fossil record and studying living organisms. Most evolutionary biologists thought darwin had the last word on macroevolution. Anagenesis: the gradual transformation of a species over time, phyletic gradualism , this theory can"t explain that sometimes a single species gives rise to a bunch of different species this is . (next bullet) Cladogenesis: when it seems to not be a gradual process, punctuated equilibrium , when sometimes a whole bunch of species changes seems to go on at one time, dramatic environment changes, challenged the neo-darwinism. Both theories have strong evidence with the fossil record.
