Competition between species played a major role in the rise and fall of hominins -- and produced a 'bizarre' evolutionary pattern for the Homo lineage -- according to a new study that revises the ...

A new genetic study by researchers at Michigan State University reveals that Borneo’s “fanged frogs” may consist of several hidden species, highlighting complex evolution and the importance of DNA in ...
