Peachy keen: ancient pits reveal origin of peach domestication
Peaches fresh from the tree or in treats like pie, jam and ice cream have been enjoyed by people for a long, long time. But, until now, it was not clear just how long it has been.

Mammals' reptile ancestors may have hunted at night
We thought the first mammals turned nocturnal to escape dinosaur predators, but 100 million years earlier, the precursors of mammals were active at night

Competition for ecological niches limits evolution of new species
A recently published study finds that competition for ecological niches limits the evolution of new species. Further, this study finds that speciation rate slows or even stops as available ecological niches fill up.

How Life Made the Leap From Single Cells to Multicellular Animals
For billions of years, single-celled creatures had the planet to themselves, floating through the oceans in solitary bliss. Some microorganisms attempted multicellular arrangements, forming small sheets or filaments of cells. But these ventures hit dead ends. The single cell ruled the earth.
