Scientists Discover Sawfish Escape Extinction Through "Virgin Births"

An anonymous reader writes: The first known virgin births in smalltooth sawfish have been documented in the wild. Researchers from the Florida Fish and Wildlife Conservation Commission used DNA to show that three percent of a Florida sawfish population was created by female-only reproduction. Dr Warren Booth, an evolutionary biologist at the University of Tulsa, who previously discovered an instance of parthenogenesis in snakes, said: "This is basically a very extreme form of inbreeding. Most people think of inbreeding as bad, but it could be helpful in purging deleterious mutations from a population." The findings were published in the journal Current Biology.

Sawfish must be a lot smarter than humans since they didn't form a nonsensical religion around it.

And you know this how?

On a serious note, I'm not even a particularly religious person, but there's not a single human society in existence (or even historically documented) that didn't develop religion of some sort. To me that would suggest that there's some long-term survival advantage.

Further, there are still boundaries to what science knows and always will be. The WHY questions, as opposed to the HOWs. As a mechanism of cultural psychology, I don't see a problem with religion attempting to give people a method to approach those questions.

Of course, as a postmodern western American, I find that religion that becomes pre- and proscriptive is oppressive and frankly obnoxious. But to throw out the baby with the bathwater by flat-out criticizing faith is overstepping pretty far.
