Both whales were pretty good at it. They caught a sea gull once every 20 days or so. |
In general, humans have long pictured themselves as separate from nature, but one of the lessons that we repeatedly learn when we study animal behavior is that animals are much more like us than we ever imagined, and we are much more like them than we had thought. |
It looked liked one was watching while the other tried, |
It was once believed that most animal behavior, from the food they ate to the places they slept, was based on instinct. This new discovery supports the growing view that animals like killer whales are very prone to learning by imitation, and that they are 'cultural' in nature. |
So it spread through the entire community. |
The whale spit fish at the surface of the pool and then sank below and waited. The gull came down to get the fish, and the whale grabbed it. |
This is an example in which a new behavior spread through a population, ... We had the opportunity to see a tradition form and spread in exactly the way that cultures do in humans. |
We want everyone to use this thing. The more ubiquitous it is out there, the better for us. |
