Some subtle points you may have missed:

  1. Human upper canines are not behind the lower canines
  2. Human incisors are larger than the canines
  3. The pterygoid is visible through the orbit
  4. The rims and ridges around the temporal opening in Gorilla are anchors for jaw muscles, all reduced in Homo.
  5. The bridge of the nose in Homo is lacking in Gorilla
  6. Perhaps I missed a few you’ll notice…
