It's remarkable, really. I think perhaps the most compelling thing about it is that it gives us the opportunity to ask and answer many evolutionary questions.

So you can end up with lots of endemics in a small area. That's what appears to have happened in Sequoia and King's Canyon.

We don't know how long they live, what kind of habitat they prefer, how many offspring they have, or how sensitive they are to human disturbance. There's still so much to learn.

Many of these species don't occur anywhere else. This is definitely a big deal.
