Animals are certainly more sophisticated than we used to think. And we shouldn't lump together animals as a group. Crows and chimps and dogs are all highly intelligent in very different ways.

Adults often assume that most learning is the result of teaching and that exploratory, spontaneous learning is unusual. But actually, spontaneous learning is more fundamental.

Preschool kids learn best when exploring, but kids in school learn best when they do things, interacting with a master. Unfortunately, our schools don't do much of either.

If you're worrying about how it's going to turn out, you aren't experiencing that day-to-day satisfaction of being with these incredible, extraordinary creatures.
