New Caledonian crows exhibit social learning, emulating each other in order to properly use tools made out of Pandanus leaves.
Dolphins have long been hailed as some of the most intelligent animals in the known world, capable of complex social interaction that rivals that of even chimpanzees. Now researchers have revealed that not only do these animals enjoy cross-species friendships, but they can also enter complex alliances that last generations.
The traditional way of the animal kingdom is that males rule, and females reap the benefits of being pampered baby-makers. Of course, there are always exceptions, especially among birds, arachnids, and even humans. However, there is one exception that came as a bit of a surprise.
