"The more I learn about animal intelligence, the more I suspect we grossly underestimate it."

An example of something that might surprise many people: animals can use medicine.

Here is a fascinating podcast that discuss the subject with researchers and experts.

Podcast description:

> Listener Andrew Chen got in touch to ask whether animals use any kind of medicine themselves. After all, our own drugs largely come from the plants and minerals found in wild habitats. So perhaps animals themselves are using medicines they find in nature.

> We think of medicine as a human invention - but it turns out that we’ve learnt a lot of what we know from copying the birds, bugs and beasts.

This podcast is highly recommended - I guarantee you'll come away amazed and humbled by the intelligence of animals.

Blue Planet II depicts a group of Dolphins visiting a certain kind of coral that emits a substance that allegedly helps them fight off parasites.

Earlier BBC documentaries show animals (birds and fish) seek the "service" of certain types of fish to clean them from parasites.

So the idea of animals using medicine is kind of presenting itself. It's not totally in your face, but it's no more out there than prehistoric humans discovering the medicinal properties of certain plants.

There is mention of this in the book ,,Wild Animals I Have Known,, (1898)
