Two Asian elephants have been spotted making use of a new tool—their own breath. When they can’t get food in their enclosure, they use their trunks as leaf-blowers to bring it closer to them.
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.
The way our ancestors ate, cooked, explored, and interacted with others has had a profound influence on our genetic inheritance. So how will modern culture shape the genetic legacies we leave to our descendents?
Many animal species use tools, from insects, elephants and sea urchins to apes, badgers and octopuses, but there are only two animals who make hooks to catch food: humans and crows. Why we both do this is a mystery — and unraveling it could explain the reasons why tool use evolved in the first place.
