oxygen levels (and multicellular life)

Cell biology Evolution Intelligent Design

Researchers: Eukaryotes got started from a merger between bacteria and archaea, without oxygen

On the whole, it might be easier to conclude that the timing is somewhat off than that complex life started without oxygen. But symbiosis is an intriguing theory nonetheless.

Did low oxygen levels limit evolution for billions of years?

Probably. The researchers propose 800 mya as the point at which oxygen increased. That’s when other researchers say they can identify chromosomes. Sounds like a rollout…
