A bunch of individuals do the same thing because they learned from watching each other or somebody else. That's what we would call culture.

Humans are particularly interesting; our culture is incredible, there's no doubt about that. In many respects, no other species matches ours. But in quite a few respects, they do, and that can help us, perhaps, to better understand our own culture. We look at the ways humans are similar to other animals, and at the ways they differ, rather than just saying, "We have culture and you don't."

It's kind of ironic that when you look at the evidence of intelligence and so on, a lot of it is anecdotal. A lot of it is, "Well, we saw this dolphin do this extraordinary thing," or, "We screwed up with our apparatus, and then the dolphins did this." And so it seems to me that the more we can actually watch them doing their thing, the better chance we'll have of making some sense of them.

Whales are cultural animals, and we're cultural animals, so although we shouldn't expect whales to do what we do, it doesn't seem unreasonable to hypothesize that we might share some of these things.

What I mean by it, and roughly what most biologists who talk about culture mean by it, is either behavior itself, or information that leads to behavior. Information that is picked up through social learning - so, from being with, watching, being taught by others. It's a way that individuals behave or get information about how they will behave that comes directly from the behavior of others.

Religion's pretty pervasive in humans. And why it's pervasive in humans is debated a lot. There are indications of things that look like religion in other animals, like chimps doing rain dances, and that sort of thing. Actually, I say that, but there's that and not much else.
