If hominids were scavengers on the East African plains 2-4 M years ago, as
we are led to believe, they likely would have developed a fondness for the
smell of carrion, or at least an ability to tolerate it. Such is quite the
opposite in modern humans. One would think that such a trait would still be
evident in modern populations to some degree, after such a relatively short
period of elapsed time, in evolutionary terms.
