Evidence for Evolution


Fossil Evidence 
            Video #1 ~ 5 minutes: Goes through the discovery of finding a transitionary fossil between fish and amphibians and how the fossil is used.



Molecular Evidence 
             Video #1 ~ 4 minutes: Look more at the structural similarities between all organism.

              Video #2 ~ 3 minutes: Looks at the differences between organisms. If they are closely related there will little to no differences however the more distance relatives will have more differences.



Anatomical Strucutres 
                 Video #1 ~ 1 minutes: Discusses homologous structures

                 Video #2 ~ 2 minutes: Discusses anatomical structures also called convergent evolution. Remember that Hyenas and dogs are not common ancestors (hyenas are closer to cats) but both evolved the same bone structure and teeth that allow them to crush bones.

                  Video #3 ~ 4 minutes: Discusses Vestigial Structures
