The later stages of evolution leading from his ape-like ancestors to man have consisted definitely in the acquirement of a larger and therefore more educable brain by man and in the consequent education of that brain.
The cranium, pronounced by Huxley to be the most ape-like yet discovered, was remarkable for its enormous superciliary ridges.
The foreheads of these two skulls have an ape-like form, obvious on comparison with the simian skulls of the gorilla and other apes, and visible even in the smallscale figures in the Plate, fig.
That still doesn't explain how a human can evolve from an ape-like ancestor, does it?
Add to that the initial shock, surprise or even terror of unexpectedly seeing a huge ape-like creature, and you can understand why there isn't any better photographic evidence.
