Document Summary

Adaptation and specialization: two major patterns in the natural world, 1. There is an enormous diversity of species occupying a wide range of very different habitats: relates to processes that generate new biological diversity, 2. Organisms are generally well-suited to life in their particular habitat: result of long periods of evolution by natural selection, natural selection: non-random differences in survival and reproduction among variable individuals, can result in evolution of adaptions, adaptation, 1. A characteristic that enhances the survival and or reproduction of organisms that bear it, relative to alternative character states: 2. 6/10 have blue eyes, 60%, frequency of 0. 6. The basis of natural selection: darwin had 2 major objectives, 1. Provide convincing evidence that species are related through common ancestry: 2. Individuals within populations are variable: not every individual is identical in a population is obvious for humans, 2.
