What I mean is, if you look at the behavior of an animal and ask, "Well, why did it do that?" and then consider the alternatives, those alternatives probably wouldn't be as successful at getting its genes around.

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.

I don't like to be dismissive of whales speaking possibilities. There is a pretty New Age-y, poorly thought set of ideas about this going around. I also think these animals benefit most from us staying out of their way. I think we learn the most by being as passive as we can, so those are my biases, and I'm sort of against it from that perspective.

Psychologists would say that the only two important forms of social learning are imitation and teaching, and they will spend time trying to figure out if animals imitate or teach. Sometimes they find they do; sometimes they find they don't. And so that's kind of the level of controversy there. Biologists would include imitation and teaching and a range of other kinds of social learning. So we would call that culture, whereas the psychologist wouldn't.

We believe we're seeing, in other animals, a process, or an attribute, that isn't fundamentally different from what we see in humans, so it seems to us to be spurious to call them different things. Now there are aspects of human culture that we don't find in animals, and that's really interesting, but there are also probably aspects of animal cultures that we don't find in humans, and that's really interesting.

I never thought of that one, that linguistics could be driving cultural things. There are some thoughts that that does happen in humans, that languages have different characteristics and that influences in some ways how different groups behave, and I suppose it might in whales.

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."
