This book had several key themes, one of the most prevalent is we don’t know shit. There are so many things I thought we as humans knew about our world, that just are unknown. So all these sci-fi shows aren’t as unbelievable as I previously thought.

Another thing is that we are new. Humans are babies compared to other species on Earth. Also we killed a lot of species.

Oh, and the Earth is still in a mild ice age. Turns out we live on the edge. Major Volcanoes are due for eruptions (Yellowstone) and asteroids are due to collide, and our climate is due to enter a big ass ice age.

But again, we still don’t know shit. We don’t really know all that much about evolution. We have bits and pieces of fossils, and it’s a big ass connect the dots. Weird.
