Black vs Brown Fur

The Mountain Gorilla lives in mountainous areas in Africa. There are only about 880 left. They've been forced into the mountains because of humans taking up all the land the gorillas used to live in. But their weakness is their fur color. When there is a predator nearby the baby gorillas can’t fight back. So if their fur was a different color like a brownish color then the babies would blend in more. If the color of their fur changes then if the climate gets hotter, since black absorbs heat, brown colored fur wouldn’t absorb as much. So I think that in a couple hundred to thousand years the color of the gorilla will change to adapt so that then they will be more camouflaged. This would most likely result in the population of the mountain gorilla to go up and, just maybe, climb out of almost extinction.
