I think he may be under the influence.
If not, thanks.
Okay–narcissism stops…now.

Earlier this summer my cover story on the meaning of life (or, at least, “life”) came out in the July/August issue of Seed. Now, at long last, the Seedsters have posted the story online. Read it here.

“I’m an evolutionary biologist who investigates the evolution of sperm form, sperm-female interactions and sperm competition. So…yeah, it’s pretty much about sperm. Wanted to bring the concept of the homunculus to life, as all illustrations of it have always been rather cartoonish.” —Scott Pitnick, Syracuse University

It’s hard to think of a word more charged with meaning–or meanings–than “life.” Some of the most passionate debates of our day, over stem cells or the right to die, genetically modified food, or wartime conduct, revolve around it. Whether we’re talking about when life begins or when it ends, the sanctity of life, or the danger of playing God, we all have an idea of what we mean when we talk about life. Yet, it often turns out, we actually mean different things. Scientists, despite their intimacy with the subject, aren’t exempt from this confusion.
Driving home at the end of the long weekend, I was amazed to see a tree here and there along the road with a touch of orange in its leaves. Fall already. And with fall comes another team of scientists to puzzle over why leaves change color.
I’ve been following this story for four autumns now, both in the New York Times, and in a series of blog posts (one, two, three, and four). It began with a simple question from one of the great evolutionary biologists since Darwin. William Hamilton argued that it takes a lot of energy for autumn leaves to produce the brilliant pigments that make fall so beautiful. Why bother, Hamilton asked.
