Chimps, Humans 96 Percent the Same

When determining the strength of a scientific theory, we need to test whether it's predictive. Darwin died before anyone knew what DNA was, but if his theory was right, once DNA is discovered and genomes can be encoded, humans and chimps will be found to be genetically similar.

Well, what do you know? Scientists have sequenced the genome of the chimpanzee and it's bad news for creationists.

[O]ur closest living relatives share 96 percent of our DNA. The number of genetic differences between humans and chimps is ten times smaller than that between mice and rats.

The amount of genetic similarity between humans and chimps makes me ponder a question that Bart Simpson once posed to Mrs. Krabappel (episode 8F22), namely, how would one go about creating a half-man, half-monkey-type creature? How gentically similar do two species need to be before they can produce a mule? Or is it not so much the genetic similarities between the two species, rather, specific similarities related to reproduction that determine this outcome? Mrs. K ruled that such an experiment would be playing God, and while I tend to agree with her, deep down, there's a little Bart Simpson in me who just wants his monkey-man.
