The man draws in many ways
I think your conclusion could be a lion face is comparatively closer to a human face compared to a shark. We are just more familiar with them.
Ask not what your lunch can do for you, ask what you can do for your lunch.
Well, great whites and other more dangerous sharks tend to be large and rather toothy. I don't think we evolved to fear sharks, so much as fear them because they have the properties of 'things that will eat the bloody hell out of us,' the fear of which may or may not be evolved to some degree.

We actually fear sharks more than we need to. We apparently aren't terribly appetizing to them, and their attacks tend to not be fatal. Given that, we wouldn't have much of a reason to evolve a fear of them directly.
The system doesn't know you right now, so no post button for you.
You need to Get Known to get one of those.
