(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, ...
Earth's complex systems interact between atmospheric, terrestrial, hydrological, cryological (ice and snow) and biological processes in feedback loops. Understanding their relationships is important for modeling their future ...
Evolutionary chromosomal changes may take a million years in nature, but researchers are now reporting a novel technique enabling programmable chromosome fusion that has successfully produced mice with genetic changes that ...
