(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, ...
The vaquita porpoise, the world's smallest marine mammal, is on the brink of extinction, with 10 or fewer still living in Mexico's Gulf of California, their sole habitat. But a genetic analysis by a team of UCLA biologists ...
