College professor PZ Meyers runs a blog entitled "Pharyngula," which is always full of good stuff. One of today's posts, about a confrontation with a pro-lifer, is a good read. It's about when life "begins."

Highlight:

this person wants a specific quote from a biology text that has the words "human life does not begin at conception" in it. That would be tough, because it's a sentence that rather boggles the brain of any developmental biologist — we also tend not to write sentences like, "human beings are not flies".
