Gay Penguin Gene Much Older Than Anticipated

Ancient penguin DNA raises doubts about accuracy of genetic dating techniques

This is potentially huge, as we thought we had a good handle on a standard rate of mutation in species.

Penguins that died 44,000 years ago in Antarctica have provided extraordinary frozen DNA samples that challenge the accuracy of traditional genetic aging measurements, and suggest those approaches have been routinely underestimating the age of many specimens by 200 to 600 percent.

Sadly for creationists, it seems that we have been underestimating the rate at which mutation takes place. So species are actually much older than we thought. No word yet, on when the "gay gene" in penguins appeared.
