Gorillas are getting smarter.
Here are three links of newer discoveries, two of which involve the same gorilla.
In one, there are photos captured for the first time of apes mating face to face, the male looking into the females eyes.
In the second, the same female wades into water, realizes it's getting deeper, and goes back with a stick to test the depth.
In the third, one ape actually learns/mimicks standing upright from watching people in a zoo. He also learns to walk on two legs. Amazing. Are we seeing what human evolution from apes may have been like?
