During the earliest evolution on earth, life probably resembled one big genetic jumble. At some time, presumably around 3.8 to 3.5 billion years before today, the very first biological species appeared – the ancestor of ...

(Phys.org)—"The origin and evolution of eukaryotes" is a tale that has yet to be told. At this point in time, it exists only as the title of a fascinating new compendium that has just been produced by the Cold Spring Harbor ...
Washington State University researchers have found "the most famous wheat gene," a reproductive traffic cop of sorts that can be used to transfer valuable genes from other plants to wheat.

(Phys.org)—A team of researchers from New Zealand and Australia has found that cultural exchange in human populations sometimes occurs at a much slower rate than genetic divergence. As the group explains in their paper ...
(PhysOrg.com) -- Genes jumping between bacteria are rather common which in part explains their ability to rapidly develop immunity to antibacterial agents. What’s not so common are examples of genes jumping between animals ...
Scientists have discovered that marine diatoms, tiny phytoplankton abundant in the sea, have an animal-like urea cycle, and that this cycle enables the diatoms to efficiently use carbon and nitrogen from their environment.
