Yeah, I mean, I might sound like it's generalizing too much, but just the sheer feat of existence is really amazing to me. And in the fact that I mean that we talked about winter already and how they survive in these really cold is just a very fascinating thing to me. The fact that, again, they have winnowed down from 33 different genera of beavers to this one genus that survives today.
