Phylogeny is the evolutionary history of a species.

a.) The evolution of a species is dependent on changes in the genome of species. Identify TWO mechanisms of genetic change, and explain how each affects genetic variation.

b.) (The picture) Based on the data in the table below, draw a phylogenetic tree that reflects the evolutionary relationships of the organisms based
on the differences in their cytochrome c amino-acid sequences and explain the relationships of the organisms. Based on the data,
identify which organism is most closely related to the chicken and explain your choice.


c.) ) Describe TWO types of evidence—other than the comparison of proteins—that can be used to determine the phylogeny of
organisms. Discuss one strength of each type of evidence you described.
