There are a number of fallacies embedded in that short post. The main
one may be just a case of poor expression, but "a hominid" doesn't
evolve; species evolve, not individuals. And of course there's no plan
involved in evolution, and nobody dreams it up.
But for the rest, the first three things were not present in the early
ancestors of humans, so didn't need to be lost. The fourth, maybe, but
consider the possibility that there are tradeoffs involved.
