Researchers announced the discovery of Afrasia djijidae, a new early anthropoid fossil. The 37-million-year-old Afrasia djijidae resembles another early anthropoid, Afrotarsius libycus, recently…

There was a time when giant insects ruled the skies and it corresponded to high oxygen levels. After the evolution of birds, about 150 million years ago, insects got smaller - despite rising oxygen…

What evolutionary reason would tiny insects 100 million years ago have for collecting and transporting Gingko pollen?  They had highly specialized hairs with a ringed structure to increase their…

If you think about it rationally, sex may be fun but it's too much work and, from a reproduction standpoint,  the payoff is uncertain. Scientists have speculated for a long time on why all…

Polar bears are evolutionarily older and genetically more distinct than believed. This largest Arctic carnivore evolved as early as 600,000 years ago, five times older than previously recognized.…

Climate change is in its fifth decade of being the big concern. In the 1960s and 70s, it was a cooling worry but now there is a warming one.  A constant in mammal's surviving numerous climate…

 Our ancestors might have started walking on two feet in order to carry food more efficiently suggests new research in the journal Current Biology. Bipedalism (walking on two feet) is one of…

Some microorganisms lose the ability to perform a function that appears to be necessary for their survival, and yet they still somehow manage to endure and multiply. How can that be?  One…

Lucy, Australopithecus afarensis, was not walking around Africa alone three million years ago.   Biologists knew that, of course, the neatly linear line from critter to modern man does not exist…

Are you ugly?  Maybe that's something else to blame your mother about. Female cognitive ability can impact how handsome males become over evolutionary time, say biologists from The University of…
