C4 carbon fixation

... C4 , see C4 (disambiguation) C 4 carbon fixation is a common metabolic pathway found in land plants ( C4 plants ). They are competitively superior to plants possessing the more common C3 pathway under the conditions of drought, high temperatures and nitrogen limitation. The C 4 cycle allows for ...

Sociobiology

... mammalian species. Further, Sir Arthur Keith (in A New Theory of Evolution ) said that "racism" could be adaptive because it enables groups with superior genetic characteristics to inbreed and preserve genetic advantages. If these arguments are right, racism might be adaptive. Such theories are ...
