<u>Answer:</u>
The ability to adapt.
<u>Explanation:</u>
If a group of species has the ability to adapt according to their environment, it will have a greater chance of survival even if there is drastic change in their environment.
But if this only happened to an individual rather than a group of animals, then whole of the group would not benefit from it since they would not be unable to evolve if it could not apply to the entire species when only one survives, leaving an endangered species.
I think 10%...................
Simply by using process of elimination the answer would be C. The ancestors of elephants didn't evolve until the dinosaurs had been extinct for millions of years, so that eliminates A. That leaves B and C. If we look at it from a scientific point of view, it wouldn't make sense if Asian elephants killed off the other species because Asian elephants were a lot smaller than most of the other species at that time. Therefore, the answer would be C. Hope that helps:)
