Question

Which mutation would be most beneficial to an elephant and its descendents?

A.a mutation of the hemoglobin allowing better oxygen-carrying capacity

B.a mutation of the tail fur so it becomes course and thick

C.a mutation of the skin color resulting in an albino (white) elephant

D.a mutation of the tusk size and length resulting in smaller and shorter tusks

Answer 1

I mean I would personally say A,

If you can increase the oxygen carrying capacity of your red blood cells, it means you would have to circulate less of them to keep cells alive, respectively this would require less energy and thus, less food to consume. That would be a competitive advantage. All the rest would't be as beneficial as that
