Document Summary
Chapter 25: the history of life on earth. Important concept: life"s history is tied in with earth"s history. A: recent discovery of water found in other planets water >>> life. Changes in gene frequency in a population: no! A: evolution of species and more inclusive taxonomic groups, the evolutionary history of life on earth, the patterns and processes that affect the evolution of biodiversity over geologic time spans. What process are responsible for the origin of species and. Patterns of evolution within and among linages. Adaptive radiation (returning from wasserman"s portion of the course) Origin and evolution of complex morphologies (last week of lecture) Goal: explain evolution in your own words by end of 3 weeks! Evolution by natural selection is a deterministic process. Do not say natural selection is a force, it is an outcome of differential fitness. What is the link between microevolution (changes in allele frequencies in populations) and macroevolution: mutation, gene flow.
