Coffee!! Desperately seeking unshot wildlife biologist

In "Frogs Evolve Teeth - Again: Mysterious re-evolution challenges evolutionary theory, scientists say", Christine Dell'Amore, (National Geographic News, February 10, 2011) tells us,
Lower-jaw teeth in frogs re-evolved after an absence of 200 million years, a new study says. The discovery challenges a "cornerstone" of evolutionary thinking, according to experts.Apparently, G. guentheri has acted in violation of Dollo's law, according to which traits lost through evolution cannot be regained.Of the more than 6,000 species of frogs, only one, a South American marsupial tree frog called Gastrotheca guentheri, has teeth on both its upper and lower jaws. Most frogs have only tiny upper-jaw teeth.
"It's a very clear case of reacquisition of a lost complex morphological structure, which, according to current thinking, should not be possible."Well one thing for sure, that frog's gotta go. Worse:
"The fact that toothlike structures appear more often than real teeth means that tooth evolution doesn't automatically occur when the need arises, Yale's Wagner noted.A friend wonders, "Did this guy get shot for saying this?"With that in mind, natural selection - the process by which favorable traits become more common over time within a species - is "not enough to explain" why the marsupial tree frog regained its lower teeth.
"I can confidently say that we don't know," Wagner said. "It's an extremely interesting question."
I dunno. Anyone seen him around lately?
Texas Darwin lobby, please note. Another one to cross off the list of what students can hear about.

Evolution has become a favorite topic of the news media recently, but for some reason, they never seem to get the story straight. The staff at Discovery Institute's Center for Science and Culture started this Blog to set the record straight and make sure you knew "the rest of the story".

- Telic Thoughts
We are a group of individuals, coming from diverse backgrounds and not speaking for any organization, who have found common ground around teleological concepts, including intelligent design. We think these concepts have real potential to generate insights about our reality that are being drowned out by political advocacy from both sides. We hope this blog will provide a small voice that helps rectify this situation.
