human appendix, a vestigal extension off the large intestine, is
homologous to a structure called a caecum, generally larger than our
appendix, and houses bacteria that aid in digesting cellulose, the main
component of plants.
how the presence of the appendix might be used to show our common
ancestry with other mammals, and determine what it might tell us about
the dietary history of humans. Provide an example with your response.
compare DNA base sequences among organisms and from this data determine
a gene’s rate of evolution. Different genes have been found to evolve
at different rates.
why some genes might have faster rates of evolution than other genes as
populations adapt to their environments, and give an example with your
