First, discuss the anatomical differences between Paleocene pro-primates and Eocene eu-primates and explain those differences in the context of the three hypotheses for why primates emerged. Secondly, recalling that the genus Carpolestes has been suggested as a transitional animal between proprimates and euprimates, which characteristics of Carpolestes suggests this relationship? Finally, discuss how the Miocene apes’ special characteristics allowed them to travel further than their ancestors did.

Whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
