"...Biology is about variation. Without variation, the world would be static and unchangeable, and species would gradually disappear as they failed to meet challenges like changing climates and environments. So as we continue our very necessary debates over ethical issues, let’s bear in mind that morality is a concept limited to our species. The natural world is a fuzzy place that doesn’t always accommodate our decidedly human need to find cut-and-dried categories."
