Biochemical Evidence

Last class, we did a Common Descent Lab where we had to determine how closely related humans, chimpanzees, gorillas, and a common ancestor are. We showed with biochemical evidence by comparing each organisms' DNA. My partner and I created models of each DNA using different colored beads. We then compared them and observed that the chimpanzee DNA was very similar to the human DNA. Therefore, they are closely related. Gorilla DNA and chimpanzee DNA are also very similar, which makes sense since both gorillas and chimpanzees are primates. This entire process is called sequencing.
