(Phys.org) —As is the case in all areas of science, our understanding of evolutionary biology is… well, evolving. Two such areas are macroevolution (any evolutionary change at or above the level of species – that is, ...
(PhysOrg.com) -- Does your robot seem to be acting a bit neurotic? Maybe it's just their personality. Recently, a team of researchers has designed computer-coded genomes for artificial creatures in which a specific personality ...
To understand how a cell works, biologists like to take it apart. By removing genes from cells in diverse combinations, researchers have now uncovered how different genes work together to keep cells alive. The research will ...
