You mean like the fact the most evolved species is the weakest on the planet?? What happened to survival of the fittest. Should we not resemble the other creatures on the top of the food chain, such as big teeth, big claws,immense size, fur to keep us warm (or cold blood for that matter. What happened to survival of the fittest, a kitten could last longer than a human when exposed to the elements.

Weak doesn't apply to the issue. Fit or unfit applies to the ability to exist within a specific evolving ecology. The species in question was extremely fit for what must be considerable ecological variation. Thus, no change took place.

The species had evolved to a point where it was the fittest. Additional change did not improve the ability to exist.

There were changes, but the individuals exhibiting the change were not successful, not fit, did not survive.
