David Ray never turns his back on his research, and with good reason. Ray and his team study alligators, crocodiles, and bats. With support from the National Science Foundation, this multidisciplinary team from several universities is mapping crocodile and alligator genomes. Reptiles resembling these have existed for around 80 million years and they are among the first reptiles to have their DNA sequenced. The research will expand knowledge beyond crocodilians to other reptiles, birds, and even dinosaurs.
