Why do animals often not understand large sticks can’t go through holes shorter than them if they aren’t going in the long way?

Question

Why do animals often not understand large sticks can’t go through holes shorter than them if they aren’t going in the long way?

Answer 1

Because they are dumb. Animals are only as intelligent as they have to be to survive just long enough to reproduce. Animals that don’t literally live or die based on their capacity to fit objects into holes aren’t going evolve the capacity to learn that big things don’t fit in small holes because they simply don’t have to.
