Description
BGYB51H3 Review Lecture Notes -natural experiments confirm or disprove macroevolutionary hypotheses of change in evolution by analyzing history of taxa and major events that characterize divergence in species and development of particular traits that distinguish them from each other -mating system affected the evolution of testes size in primates -independent contrasts involve comparing traits in sister taxa with different mating systems -synapomorphies distinguish a group of taxa from other groups that are connected to a common ancestor -synapomorphies can be ancestral traits of a particular group -selective pressures that cause convergent evolution are rare while homologous traits are more likely to occur, especially at the DNA level -one allele favoured fixes one allele across all populations
