Scientists examining the genomes of West Africans have detected signs that a mysterious extinct human species interbred with our own species tens of thousands of years ago in Africa, the latest evidence of humankind's complicated genetic ancestry. The study indicated that present-day West Africans can ...

Dwarf Tyrannosaurus rex species probably did not exist, study says
For three decades, paleontologists have been split over a provocative question: Did a dwarf species of Tyrannosaurus rex once exist? In 1988, paleontologist Robert Bakker and his colleagues at the Cleveland Museum of Natural History reclassified a specimen that had been discovered in 1942 and ...
Scientists have discovered what could be the world's oldest forest, potentially rich in information on the link between forests and climate change, according to a study published Thursday in the journal Current Biology. The title of world's oldest fossil forest had previously been given to ...
