In today's Science , Lewis C. Cantley and John Asara of Harvard announce the results of DNA workup on bones of a T. Rex John Horner, right, excavated in Montana five years ago
“Our results at the genetic level basically agree with what has been seen in skeletal data,” John M. Asara of Harvard said in a telephone interview. “There is more than a 90 percent probability that the grouping of T. rex with living birds is real.” Asara said.
This will cause a major shakeup in the family tree of vertebrates , as T. rex genetic
makeup overlaps more with ostriches and chickens than such toothy modern reptiles as alligators. Mary H. Schweitzer of North Carolina State University discovered the still smelly preserved soft tissues in the bones.
Evolutionary biologists compared the dinosaur protein with similar protein from several dozen species of modern birds , reptiles and amphibians.
