That's what waterproofing oils from their anal glands are constantly being lathered onto to keep them as sleek and waterproof as possible. But below that, you get more into some more downy, dense layers that are even softer. And so that is what's kind of right up against their body. The fur is so dense. I've heard it. One stat I seem to recall is like 23,000 hairs per square centimeter.

And so you can imagine a square centimeter. That is not large, but that is a ton of hairs in that area.

And so that density is probably about 25% of the beaver's insulation through the winter. And so even all that hair, because they're in the water so much, doesn't do all their needs to stay insulated. And that's why they rely so much on their fat stores as well to accommodate the rest of their insulation. But it is incredibly dense fur and it is in the interior very soft. Yeah.

So that varies. The tail, I think, was definitely relied on at certain times in certain people that live in climates where that was needed throughout human evolution. They have certainly relied on beaver tail as a fat source. And beaver meat as well is something that has a lot of importance in certain times of human evolution.

I can't really speak to what the first listener was talking about, about wrecking the world. I think that would be a little bit extreme. Beavers, like I said, wanted to start here that for seven and a half million odd years, they've been on this continent shaping and transforming it in different ways. And We, at one point, had between 100 and 400 million beavers across North America.

And in the course of about three centuries, in about the 1600s through the early 1900s, that winnowed down to about 100,000 beavers.

And so we are very lucky that they didn't become extinct or endangered. But their populations at this point are very patchy, dispersed, and in many places recovering. But beavers do not need us to keep them kind of their populations in control. I mean, they for all those years, they have had
