mammals show the same exact arrangement of bones from the shoulder all the way down to the tips of the digits despite the fact that they all share very different functions. This provides support for the fact that all species evolved from one common ancestor. Even further supporting the evidence of evolution that kind be found in the study of homology are the study of the patterns of development in different species. Many organisms express even further anatomical homologies during embryonic stages that are not expressed in adulthood. An example of this can be seen when comparing the embryos of vertebrates, which all have a tail behind the anus, as well as throat arches. These throat arches develop into very different structures depending on the organism, such as ears in humans and gills in fish. Finally and probably most convincing is the evidence found during the studies of comparative biochemistry which supports the theory of evolution. Comparing species containing similar genomes can reveal many things such as recently relative

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
