Dino Protein is for the Birds
Join commentators Dave Micklos and Jan Witkowski for a lively discussion of DNA in the news from world-renowned Cold Spring Harbor Laboratory! Dino Protein is for the Birds Organic material from a T. rex bone shows that birds are the closest living relatives of dinosaurs. In echoes of Jurassic Park, organic material has for the first time been recovered from a dinosaur fossil. Protein fragments from a 68 million year old T. rex bone most closely match samples from a chicken, providing further evidence of the evolutionary relationship between dinosaurs and birds.
