> > dhw: Secondly, what are you claiming here? All DNA consists of biochemicals. You can use the same materials to create any number of new things from the beginning. The question is whether there is a direct line from species to species, or in this case, from brain to brain. From hominids to homos, there is a continuous expansion, through the addition of new cells. Do you or do you not believe that our brains, together with their additional "layers of neurons", evolved from earlier brains?
