![]() The divergence between human and chimpanzee ancestors dates to approximately 6.5-7.5 million years ago (see reference 3). The high homology between chimp and human mtDNA does points to the same single ancestor. This has been explained by differences in the mutations rates (see reference 2). A man is at a disadvantage to fight hand to hand against a wild animal, man, sacrificed his evolution points to acquire adequate abilities to hunt and think. Through comparison with the human genome, we have generated a largely complete catalogue of the genetic differences that have accumulated since the human and chimpanzee species diverged from our common ancestor, constituting approximately thirty-five million single-nucleotide changes, five million insertion/deletion events, and various. Hand size comparison between chimpanzee and human hands. ![]() ![]() The nuclear mutation rate on the other hand is higher in humans than in chimpanzees. Among the other advantages chimpanzees have is that they have huge fingers and toes designed for grasping and squeezing. Geneticist Richard Buggs has tried to refine the methods for comparing human and chimp genomes. They also have completely different social constructs: bonobos are female dominated with a friendly, peaceful demeanor with outsiders, while chimpanzees have a male dominated community that doesn’t take well to outside visitors. Interestingly, humans have substantially lower levels of mitochondrial genome diversity compared to chimpanzees. Besides the obvious size difference the human brain is about three times larger than the chimp brain little has been known about how the human brain and the rest of the nervous system. They have physical differences: the color and tendencies of their body hair, lips, and skin. The nucleotide difference between the complete human and chimpanzee sequences is 8.9%, the difference between the control regions of the two sequences is 13.9%, and the difference between the remaining parts of the sequences is 8.5% (see reference 1). ![]() Chimps, on the other hand, have much longer fingers and shorter thumbs, perfect for swinging in trees but much less handy for precision grasping. While the mitochondrial DNA (mtDNA) from humans and chimpanzees is not identical, it is highly similar. We have a relatively long thumb and shorter fingers, which allows us to touch our thumbs to any point along our fingers and thus easily grasp objects. ![]()
