So, are the conclusions based on science? Not speculation or correlation re: size of insects and oxygen density. 35% oxygen to 21% doesn't seem to account for a millipede going from 8 feet to 15in.
- forgotmypassw 11y agoThe oxygen level is only a single factor here, there are probably many more that influenced the size.
- JumpCrisscross 11y agoThere's compelling evidence for a causal link. Hundreds of millions of years ago the atmosphere was much more oxygen-rich than it is today. Insects were also far bigger.
