"I think it is an amazing step forward for our community if it can be pulled off," said Robert P. Guralnick, an expert on evolutionary trees at the University of Colorado, who is not part of the project. ...

A Mammoth Find in Iowa

A nearly complete mammoth skeleton has been found buried on an Iowa farm about 60 miles southwest of Des Moines. The bones were largely undisturbed, which has allowed scientists to gather evidence that could help show what the area was like more than 12,000 years ago, when the animal died. ...
