VOA Special English

VOICE TWO:

John Asara and Lewis Cantley then processed the proteins. Both work at Harvard University Medical School and Beth Israel Deaconess Hospital in Massachusetts. Harvard University researcher Chris Organ compared the molecules of dinosaur protein with similar protein. The similar material came from many kinds of modern reptiles and birds.

Mister Organ was lead researcher. He said the researchers plan to continue their molecular comparisons. They say they now will study T. rex protein with reptiles and birds other than the chicken.

The researchers also studied material from another large prehistoric creature -- a mastodon. They found that it is similar to the modern elephant. This finding is not a surprise, because the elephant looks very similar to the mastodon.
