How Evolutionary Biology Explains So Much of This Interesting Stuff

I've found so many parts of the book really interesting and one of those that you touched on and made me aware of things that I hadn't ever considered never mind known before about topics I'd heard was kind of two landmark events. Photosynthesis is the first one of the first kinds of metabolism that evolve on the planet and it gets going around to billion years ago or so or even more and what happens is oxygen. You get all these plants taking off photosynthesizing organisms i don't know if you even call them technically plants at that point because they're early in life's early stages, algae and that kind of thing. And now we have bacteria that can finally evolve that that can
