Eli5 How do animals know to make eye contact?

Maybe not all animals but most mamals at least. Does it imply the awareness that they see from their eyes and can identify them on other animals? Is it something instinctual?

In my experience most animals *don’t* care about eye contact. Even most mammals – you look them in the eye and there’s just nothing there. If they do, it’s because they simply don’t like being looked at. Being looked at usually either means they’re being hunted or otherwise threatened.

Humans specifically communicate a ton of information through our faces and especially eyes – that’s why we have white sclera and eyebrows, to make our eyes more visually communicative. Some great apes use eye contact to communicate aggression, but even they’re not quite as dependent on eye-to-eye communication as humans.
