A quirk of computer numbers and simple arithmetic defeats my digital creatures

A quirk of computer numbers and simple arithmetic defeats my digital creatures

Artificial life systems have a reputation for finding all sorts of obscure bugs in your code, no matter how rare or unlikely the conditions to cause the bug are. I’ve got an oddball one. It causes a run time error and shuts down the entire system, and it is an extraordinarily unlikely event, happening once …

Ep 239: Monkey brain business

Ep 239: Monkey brain business

Monkey brain business Primates, from the littlest monkeys to the largest apes, have rather large brains for their size. They also have high neural density, meaning that they pack a large number of neurons into whatever size brain they have. With culture, tool use, and even the beginnings of language, we take a bit of …

Introducing the dorg, we’ll never be assimilated!

Let’s use artificial life to evolve intelligence. Because AI is hard; evolution is easy. I’m not the first one to think of this idea. Quite a few people have taken a stab at it. It’s not even the first time I’ve implemented something to play with the notion—nymphs, grubs, figures… It’s very important that whatever …

Ep 238: That’s a good dog

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 …

Ep 237: Raccoons, brains, hands, and clever disguise

Raccoons, brains, hands, and clever disguise Raccoons have surprisingly crowded little heads. With as many neurons as a similar sized monkey, these furry little bandits have nimble hands, and a knack for cheating on intelligence tests.

Ep 236: Brains on the wing

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 …

Ep 235: Elephants, their big brains and handy faces

Elephants, their big brains and handy faces The largest animal on land also has the largest brain. With complex social lives, cooperative problem solving, self-awareness and tool use, the elephants also have brains that have three times the number of neurons that our brains do. Join us as we take a look at elephants.

Ep 234: Seals and sea otters

Ep 234: Seals and sea otters

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 …

Ep 233: Whales, songs and cerebrum

Whales, songs and cerebrum The largest creatures on the planet also have some good-sized brains. Why? What do they do with such large brains and how did they get them in the first place?
