Primate morality:
Some animals are surprisingly sensitive to the plight of others. Chimpanzees, who cannot swim, have drowned in zoo moats trying to save others. Given the chance to get food by pulling a chain that would also deliver an electric shock to a companion, rhesus monkeys will starve themselves for several days.

relativistic morals:
In a debate with between Abraham Lincoln and Stephen A. Douglas, Douglas claimed that Lincoln was a “Nigger Lover”. In response Lincoln said:
I will say then that I am not, nor ever have been in favor of bringing about in anyway the social and political equality of the white and black races - that I am not nor ever have been in favor of making voters or jurors of negroes, nor of qualifying them to hold office, nor to intermarry with white people; and I will say in addition to this that there is a physical difference between the white and black races which I believe will forever forbid the two races living together on terms of social and political equality. And inasmuch as they cannot so live, while they do remain together there must be the position of superior and inferior, and I as much as any other man am in favor of having the superior position assigned to the white race. I say upon this occasion I do not perceive that because the white man is to have the superior position the negro should be denied everything.
Now, Lincoln was far ahead of his time in promoting increased rights for blacks. However, If someone said this today, they would be labelled as the most vile of racists. An abundance of similar quotes can be found from people that were considered progressive, or “ahead of their time”, in relation to a variety of issues such as women’s rights, racial equality, animal rights, civilian casualties in war, child abuse, rape, etc…
This shows that as a whole, the human race does have have a relativistic moral system, that changes over time. Some people are ahead of their time(Lincoln), most people are about average, and some people are slow to adopt changs (racists and sexists of today).
Could it be said that (having one’s morals moulded by the society one lives in) is a religion? Probably not.
As a corollary, this shows that people with absolute unchanging morals derived from scripture do not exist in today’s society (ignoring the few crazy literalists). If a person claims to derive absute morals from the torah (or bible, or koran, etc…) then they must accept the whole book as there is nothing in the book that tells a person which parts to accept and which to discard. Given that almost no-one lives their lives by the atrocities in the pentateuch (slavery, rape, child sacrifice, etc…), they must make their moral decision on which parts to “pick and choose” from another source - the internal knowledge of what is right and wrong, as changed by society over time.
