Why do chimpanzees have a shorter gestation period & don't live as long. Why because chimpanzees are not setup to live as long. This is why blacks also have a shorter gestation period & don't live as long. Sorry but it is largely genetic. A short gestation period & yet an earlier time to walk in both Blacks & Chimpanzees shows how blacks are setup to mature at a quicker rate & die at an earlier age. These are facts & reality. Not the fantasy land of racial biological equality that the liberal idiots have put forth.
