ANT101H5 Lecture Notes - Lecture 4: Dual Inheritance Theory, Macroevolution, Mate Choice
Document Summary
Lecture 4 - modern theory of evolution, human variation and biocultural evolution. Modern theory of evolution aka the modern synthesis incorporates the old ideas of darwin with what we know about evolution now, including the role of variation plus natural selection. Page 60-61: variation in a population, is produced by mutation, which is the only way to get a brand new allele. Natural selection is the most important long term factor in the direction of evolutionary change. Evolution is the change in the genetic structure of a population, which mostly in macroevolution. Evolution: long time scale (macro-evolutionary, which is when there are large visible changes in a population. Ex speciation, this usually takes 100"s of generations): shorter time scale (micro-evolutionary, which is when there is a change in the allele frequency from one generation to the next. Over time this leads to a shift in the allele frequency).
