A problem with bringing up blacks is that they have pre-hominid ghost genes. They have ancestors in their DNA to an earlier ancestor than all the prior-hominid species.

The belong to a distinct hominid ancestor distinct from the other races.

This is so problematic as blacks belong to a different genera. Their correlation of genes to all the other races is as distant between wolves and coyotes if not more so.

Different species display different behaviors. Regardless whether they are IQs are the same or not... Accounting for different species displaying different behaviors is like the dog giving up his bed for the cat in the house.

It is like having cats and dogs in the same house...the cat doesn't seem to mind but the dog is without space.
