> anything is a social construct

Well, no, the physical laws aren't social. An apple falls whether there is a social group to see it or not.

And yes! Animals are a perfect example. Mother Nature came up with a nice strategy for maximal benefit in a social group, and she encoded it in our instincts and intuitions.

But that doesn't mean it's perfect. I have an instinctual fear of fire - but it's still better to cook my own food.
