iskandar says:

"So to answer the question why we are moral, it is because our ancestors, who were apes and shared the common ape heritage of being social animals of a certain kind, were rule followers, and had to cooperate to survive and gain mating opportunities. And then we evolved language. "

Morality is an "acquired dialect", which is a very useful metaphor. Like a dialect, it is conventional, and varies by geography. It is not inborn (although the capacity to acquire it, like that of language, is), and it doesn't correlate with biology (a Sicilian raised in Japan would speak Japanese, not Sicilian). This is what Sayre-McCord refers to as social conventions. And these things evolve at the social level, not (in general) at the biological. So to explain why, for example, it is <A href="http://en.wikipedia.org/wiki/Prohibited_degree_of_kinship" linkindex="123">regarded as moral</A> to marry a first cousin in Louisiana, but not in London, while marrying within "seven degrees of kinship" in Orthodox society, or marrying anyone with the same family name in Korea (but a first cousin of a different name is acceptable) are considered taboo; these things are best explained in terms of the historical process at the level of social institutions, conventions, economic and cultural factors, rather than biology.
