mattrussell2319, Basically, eukaryotes may have been around a lot earlier than we thought. People took the absence of eukaryote-specific sterols in the fossil record to mean eukaryotes weren’t there. But if you look for sterol precursors, there are lots of them. So maybe eukaryotes were around, they were just using the precursors instead of the sterols.
