In another thread I said morality is either derived from biology or the only other option is some kind of magical source. Does morality stem from a magic sky man sprinkling pixie dust in the eyes of newborns? Do we pull it out of thin air?
It was said this is a false dichotomy. So I'd like to know what is the source of human morality?
There is evidence learning is not the key. Young children express moral choices unrelated to learning. And if you claim moral behavior is purely learned, then what motivated humans to teach it in the first place if it was not a biological/evolutionary basis?
There is evidence morality evolved. Animals express moral behavior.
There is evidence morality is associated with the physical brain because brain damage can change one's moral behavior.
I interpret this as evidence morality is biologically based. A recent study of fraternal and identical twins supports that conclusion:
Are We Programmed For Kindness?
So if I've presented a false dichotomy, magic or biology, then where do other people believe morals originate from?

In other words, do we have a "goodness gene" that encourages us to do the right thing?
Ruston thinks the answer is yes, although such a gene is obviously expressed differently in some persons than it is in others.
He bases that opinion on decades of analyzing data he collected through the University of London Institute of Psychiatry Adult Twin Register, the source for many studies about twins and genetics.
Ruston submitted a series of 22 questions to 174 pairs of identical twins, who share all their genes because they came from a single egg, and 148 pairs of fraternal twins, who share only half their genes because they came equally from the mother and the father. ...
... So identical twins should agree on moral issues twice as often as fraternal twins, at least if genetics has any influence on human compassion.
And, he says, that's precisely what he found.
