Document Summary

Defining evolution, change in the genetic makeup of a population over time, seen in fossil record, laboratory experiments, natural populations. Ii. evolutionary theory: in everyday speech, theory means an untested hypothesis or guess, in science it means a system of well-supported ideas, refers to our understanding of the mechanisms that result in genetic changes in populations over time. Before darwin: erasmus darwin: biologists suggested that species had changed over time before charles darwin, charles darwin"s grandfather. Artificial selection: darwin had observed variation and artificial selection in plants and animals by pigeon breeders. Alfred russel wallace: independently arrived at the idea of evolution by natural selection in 1858, darwin published on the origin of species in 1859. Both men are credited for the idea of natural selection. Evolution does not equal natural selection: natural selection is one mechanism by which evolution can occur.
