Claim: Complex cells started without oxygen

A way to bridge the gap:

Since the 1960s, many experts have argued that the emergence of eukaryotes (cells containing a clearly defined nucleus) happened in response to the oxygenation of Earth’s surface environment.

But a team led by the universities of Stanford and Exeter say recent advances in the Earth and life sciences challenge this view.

Their review says these breakthroughs “decouple” the emergence of eukaryotes (known as eukaryogenesis) from rising oxygen levels, and suggest eukaryotes in fact emerged in an anoxic (no-oxygen) environment in the ocean.

Yes, the ham sandwich was invented that way too. It started without any ham…

    This is just not good science. The presence, or lack of, oxygen does not explain the origin of a cell’s nucleus.

    Actually (heh) the ham sandwich probably started with ham. In most cultures the combination of bread and meat started by dipping meat or lard in coarsely ground grain. The envelope form is more universal than the two-slices form.

    There are many eukaryotic organisms that can revert/resort to anaerobic if necessary.

    Saying “the emergence of eukaryotes happened in response to the oxygenation of Earth’s surface”, is like saying, “the emergence of airplanes happened in response to the arrival of humans on Earth”. It may be true but tells you nothing about HOW it happened. Some scientists like to dance around the margins of evolution without addressing any actual natural processes. Then they pretend that they have added to our knowledge about evolution. (“evolution” is used here as changes in lifeforms over mega-years, rather than as “natural, Darwinian-like processes”.)
