c. 30-20 Million BCE: Evolution of Advanced C4 Photosynthesis in Plants

Advanced C4 photosynthesis, an evolutionary adaptation in plants, emerged 30-20 million years ago in response to decreasing atmospheric CO2 levels, enabling more efficient CO2 fixation, especially in hot, dry environments, and playing a crucial role [...]
