This is a piece written by Peter Singer (an author we'll see quite a bit of in my Philosophy and Public Issues course this term). One of the central questions addressed is:

I'm curious what readers of this blog think about the connection between biology and morality/moral behavior. How much can folks thinking about ethics learn from the sorts of experiments described in the article?
