More than fifty years ago, humans were pretty well convinced that they were special, different from the rest of the animal kingdom. That all changed in 1964 when Jane Goodall reported her observations of tool use in chimpanzees. Now we have evidence that Goffin's cockatoos, parrots that don't use tools in the wild,…
Despite the wide variety of species that have complex social structures – elephants, monkeys, chimps, dolphins, giraffes, wolves, corvids, and lots more – many have argued that jealousy requires a sophisticated understanding of the self and of other's social goals and desires.
It's hard to study intelligence in humans — our cultures are incredibly complex, and what counts as "smart" is defined as much by our societies as it is by our genes. So some researchers have turned to chimpanzees to understand what actually gives rise to intelligence in the brain.
To look for aliens, most people peer towards the sky. But if you look down, you'll discover they already live among us. These aliens have brains, like we do, but they're mostly inside their arms, and each arm acts as if it has a mind of its own.
There are many things that make the octopus a strange creature, but one of them is that each of its eight arms has an essentially infinite number of positions, and yet each arm operates independently. How does an octopus keep from tying itself in knots?
Fork-tailed drongos are among the most clever of liars in the animal kingdom, deceiving other animals in order to steal their food. The avian thieves have discovered a way to keep their targets in the dark. They do it by using lots of different kinds of lies.
When you think of Atlantic cod, you probably think of a strip of fish, battered and fried. But new research suggests that the fish might be able to use tools, and that might cause us to rethink how we evaluate tool use in other animals.
