Hank Green’s video about how fish transitioned onto land is one of the most fascinating things I’ve encountered in years.

I would not have expected this but more oxygen is available in the air than in water. I don’t know why I thought otherwise. Just seems like water is denser and a lot of our o2 comes from marine plants anyway…

But yeah it’s kind of inevitable. There’s more energy here.
