Document Summary
Wright saw an important role for population structure and genetic drift in evolution. Fisher disagreed and argued that most evolution occurred in large populations by natural selection. The difference between the two was mostly about the difference in importance of genetic drift. North versus south facing slopes have different microclimates, even though the habitats are so close together. A group of individuals of a single species occupying a given area at the same time. Mark-recapture size tool for mobile population. The movement of individuals from one population to another. Important for animals prerequisite for gene flow. The movement of genes from one population to another. What proportion of all genetic variation in a species is due to difference between populations? (within group vs between group) How is diversity distributed within vs. between populations. Recognizable differences between humans of different ethnicity variability between groups. 90% of the variation is within populations compared to between populations.
