Eyesockets

It should come as no surprise to anyone that with everything else that's been changed, our bodies too have undergone alterations. One of the most striking things I noticed is the change to our eyesockets. The human skull now looks like this:



As you can see, the back of the sockets contains a small opening for the optic nerve. The rest of the back of the sockets is now covered by a layer of bone. Those pieces of bone were never there before, and I should know, we had a mock skeleton in out biology classroom and this is the kind of thing I know I would have noticed. Our old skulls looked more like this picture:



I realize this isn't a real skull, but a model of a skull... but this is how our skull used to look. Why would somebody making a model leave out a detail like the bone at the back of the eyesocket and put so much effort into making the rest so realistic? Perhaps this person also does not remember any bone being there.

I can see certain advantages to this new feature, should anyone experience catastrophic injury to the eye, the skull won't be so easily penetrated and the brain will remain protected. That said, it is still unnerving to consider that our very bodies and DNA have been changed without our knowledge

Which skull do you remember?
