That’s a good dog

Alright, I agree, some dogs are smarter than others. Some dogs are downright dumb—but we still love them. Still, depending on the dog, they can show language and memory abilities as good as those shown by two year old human children. And yet, there’s nothing special about the dog brain. It is the size expected, and has the number of neurons expected for a non-primate mammal of their size. How does their average brain make some dogs so smart?

Brains on the wing

If you compare brain size to body size, some animals have much more brain per pound than others. That includes the primates, who climb and swing through the trees. It also includes parrots and ravens and crows, who fly through the trees. Join us as we talk about some surprisingly sophisticated bird brains.

Seals and sea otters

Last time we talked about the whales, and how some of them turn out to be rather clever. The whales and dolphins aren’t the only mammals who have returned to the sea. We’ve also got things like seals and sea otters. Some of them are rather clever as well. In fact the sea otter is a tool user. Does going back to the ocean make a species smarter?

Octo smarts!

It’s a rough life. With no shell, octopuses are a delicious boneless morsel, just waiting for some big something or another to gobble them up. This bite-size snack uses its ability to hide, squeeze into the tiniest of hiding places, and its brains to find something to eat, and avoid being someone’s dinner. Join us as we consider the octopus, along with its relatives the squid and cuttlefish; their intelligence; and where they came from.

In search of intelligent animals

We spent nine months looking at the human brain, and one episode looking at the cognitive abilities of plants. Today, we try and figure out how to figure out whether or not an animal is intelligent.

Can plants remember?

It was a throw away question from Phil, something he said in the middle of an episode as a joke. Obviously plants have no memory—how could they when they have no central nervous system, no brain with which to learn. However, a bit of digging and the answer turns out to be a bit stranger than expected. Join us as we talk about plant communication and memory.
