Neanderthals

It is my theory that Neanderthals where the first bimbos and bulls, but unlike modern bimbos and bulls. Neanderthal bimbo where most likely able to breed with homosapien males, and that the whole species where all bimbos and bulls. Which gained is the immunity to diseases and the resistances to extreme weather. And because Neanderthals bred with homosapiens those first bimbos and bulls went extinct.

In the modern day all humans have a 0.01% to 0.1% of Neanderthal DNA, and non bull males might contain a mutanted gene of the bull DNA that causes male sperm to reject bimbo eggs,but this is just a theory. Now I must figure out how this gene reawakened in modern humans
