Question

you often hear people saying dolphins are clever, but how do we rank animals’ intelligence?

In: Biology

Answer 1

By comparing how they fare in tasks we as humans can perform at different stages in our development.

For instance, a toddler will not understand “object permanence” ( this means, an object is still there, even if you cannot see it right now becasue it might be hidden under a blanket), while an older child will.

Many intelligent animals do understand object permanence, which puts them in this category at the level of little children.
