Perhaps I should have qualified this. Variations have occurred. Skin Colour, Build, Sexual Preferences, etc. But these are only minute random changes in our DNA. All Homo Sapiens have nearly identical DNA, we only vary from chimpanzees by around 2%. When DNA varies to the point where speciation occurs then a change has occurred as opposed to variation. Speciation is the point where a single species has varied in two isolated communities so that precreation no longer occurs or is possible. Say between us and Neanderthal. (this is not a hard and fast rule)

Well ... I'll give you this one. But yes, I am basically saying that it proved beneficial (pragmatic) to be nice

Tina ... Genes actually don't have a personality. Compassion is a feeling/emotion an extension of basic instinctive emotion of SADDNESS. Intellect then thinks of possitive ways to respond....thus compassionate actions.

Wow ... This is going to be tough! Without spelling out all the biology, here I am referring to the underlying chemical makeup that is responsible for our moods, etc. and governed by the DNA we inherited ..
cool bananas ... greg
