I have a sense this is not actually true, but we want it to be true because it aligns with our modern day morality and ethical code. If we accept the premise that all traits are a result of a social environment rather than a genetic basis, does this only apply to human beings? Other mammals which are not particularly social end up exhibiting traits they never seem to have learned. Both humans and animals exhibit some traits with near universal consistency. How would we explain such a dramatic difference between how species express traits?
