While I agree with the fact that it is not necessary to diverge as far as
ape faces for this experiment to work, I respectfully disagree with both
of your conclusions.

This is neither a racist nor a biological phenomenon, but a cultural one.
If we had been brought up in a community of apes, with limited exposure
to humans, we would have exactly as much difficulty differentiating
the human faces, and no problems with the ape ones.

In other words, the ease of distinguishing faces is directly proportional
to how closely those faces correlate to the faces we saw frequently as
we were developing the face-recognition cognitive skillset.
