Evolution & Plant Life
3.8 billion years of life on Earth, the mechanism that drives it, and the photosynthesis that made everything else possible.
Evolution is the unifying theory of all biology. Everything else — cell biology, ecology, human anatomy, microbiology, even modern genetic engineering — makes sense only in the context of natural selection working over billions of years.
