A genomic atlas of Nematostella vectensis reveals how primitive animals created multiple cell types millions of years ago, without new genes.

At first glance, this mammal looks like a horse gone terribly wrong. But, in reality, Chalicotherium is far from a botched ...

A University of Montpellier study published on September 1st in the Proceedings of the National Academy of Sciences reported that human intervention over the last millennium drove a sharp divergence ...

For over a century, scientists have wrestled with one of biology’s most fundamental mysteries: how the first animals evolved. These earliest creatures emerged more than 600 million years ago in ...

The conservation of genome regulatory elements over long periods of evolution is not limited to vertebrates, as previously ...

Researchers from the Canadian Museum of Nature (CMN) have identified a new species of rhino that once roamed Canada's High Arctic 23 million years ago. The extinct rhinoceros, described in the journal ...

Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) at the University of Oxford have uncovered a clue that may help to explain why the earliest evidence of complex ...

In five cases where vertebrates evolved monogamy, the same changes in gene expression occurred each time. In many non-monogamous species, females provide all or most of the offspring care. In ...
