Polar bear evolution tracked climate change, new DNA study suggests
A whole-genome analysis suggests that polar bear numbers waxed and waned with climate change, and that the animals may have interbred with brown bears since becoming a distinct species millions of years ago.
Mobile DNA elements in woolly mammoth genome give new clues to mammalian evolution
The woolly mammoth died out several thousand years ago, but the genetic material they left behind is yielding new clues about the evolution of mammals. In a study published online in Genome Research, scientists have analyz ...

30,000-year-old DNA preserved in poo a window into the past
(Phys.org)—Murdoch University DNA scientists have used 30,000-year-old faecal matter known as middens to ascertain which plants and animals existed at that time in the hot, arid Pilbara region of North ...
New technique fills gaps in fossil record
University of Pennsylvania evolutionary biologists have resolved a long-standing paleontological problem by reconciling the fossil record of species diversity with modern DNA samples.
Why crop rotation works
Crop rotation has been used since Roman times to improve plant nutrition and to control the spread of disease. A new study to be published in Nature's 'The ISME Journal' reveals the profound effect it has on enriching soil w ...
