Document Summary
Definition of evolution changes in the genetic composition of a population during successive generations complex of processes through which living organisms originated from non-living matters and have become diversified and modified through sustained changes in form and function. Key concepts diploid individuals carry two alleles at every locus: homozygous, heterozygous. Current controversies surrounding neodarwinian synthesis rates and geometry of evolution (punctuated equilibrium) epigenetic inheritance: mutation completely random, macroevolution (species selection) level(s) at which natural selection operates (genes, individuals, species, higher taxa?) Our debate: pro-darwinian evolution: examples of natural selection: pepper moths natural selection in action. 19th century pollution in great britain blackened tree trunks a mutant black moth was better camouflaged through the population population genetic models applied to peppered moth morph frequencies also apply to other organisms. 2; should see two centromeres one, telomeres in humans head to tail repeats of the bases.
