The real controversy comes with anthropologists - not all, but some - who see themselves as studying culture, and they then see culture from the perspective of humans, which is what they study. From their perspective, or, from some of their perspectives, it's sort of heresy to even talk about culture in any other animal. Others would say, "Yeah, you can talk about it, but our definitions of culture are so utterly different from yours and include things like values, and so on, which you've never shown to exist in any of these other creatures."

Studying the behavior of large whales has been likened to astronomy. The observer glimpses his subjects, often at long range; he cannot do experiments, and he must continually try to infer from data that are usually inadequate.

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.

I don't think in biology it's very controversial at all. Whether certain behavior is culture or is not culture is argued. I think virtually all biologists would agree that some animal behavior is culture. Bird song is a good example.

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.

Culture is not usually one of the criterion for personhood, but it has been argued that culture is sort of a medium for a lot of these criteria, such as empathy, and so on.
