“There is no one way that creatures start development, grow and form sexes — there are many varied ways. Unfortunately, humans seem to forget this fact when we find ourselves turning to nature to guide us through difficult choices, such as arguments about whether life begins at conception, or over the proper structure of the family. Or, more recently, regarding the morality of cloning. Whether we’re talking about raising bigger cattle or growing life-saving organs or trying to “live forever,” both sides like to stress their abilities to judge what is “natural.” Judging from Komodo dragons, lizards and sharks, the answer seems to be that for reproduction, almost anything goes. And that is the point. 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.”
