Revueltosaurus skeleton unearthed at Petrified Forest upsets dinosaur tale

...sibly herbivorous crocodilians," Parker said. "The convergent evolution of the teeth is what makes them look like herbivorous dinosaurs. That's the only thing similar in the entire skeleton.

...ts but for different reasons--and is an example of convergent evolution. It was only a few years ago, in 2003, that sensitivity to a bitter compound known as phenylthiocarbamide (PTC) was mapped in human genes. "That gene was found to be controlling whether you can taste PTC or not," says Stone, an associate ...

Looking at the convergent evolution of sodium channels in these fish helps neurobiologists identify important parts of these proteins relevant to human health, adds Zakon.

They also suggest that the current study provides a framework for further investigations into the brain and behavior of cetaceans, whic...
