It wasn't possible to evolve complex life forms because there was not enough oxygen in the atmosphere, and there wasn't enough oxygen because complex plants hadn't evolved 6 only when land plants came about did we see a more significant rise in atmospheric oxygen," study co-author Timothy Lenton from the University of Exeter in the U.
