Document Summary

Natural selection; does not yield perfection - only improvements over what came before. Predictions of the components of the evolutionary process: since there are fossil remains of ancients life, we should be able to see species changing over time descent with modification (adaptation) In fossil records see one line of descent dividing in two or more. Missing links or transformational forms should occur in layers of rock that date to the time when the groups are supposed to have diverged: expect that species show genetic variation for many traits.
