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.
Yes, the ham sandwich was invented that way too. It started without any ham…
According to the new thesis, the erosion of mountains provided nutrients that were hitherto unavailable, that helped life forms get started. Sounds like a rollout, actually.
It’s probably not anywhere near as simple and certain as Catherine Jessus is making out. Viruses don’t likely do enough to create placentas. But the main point is, this definitely isn’t yer old biology teacher’s Split-the-Desk Rant for Darwin!!! Stay tuned.
The last eukaryotic common ancestor (LECA) seems to have been pretty complex. So when and where does all that random assembly of vital equipment for life from free-floating chemicals actually happen?
Already complex? No intermediate forms? Where have we heard that before?
No wonder these fields tend to be marked by a lack of progress.
Also, here’s a 2017 Abstract from Nature, noting that “Our results expand the known repertoire of ‘eukaryote-specific’ proteins in Archaea, indicating that the archaeal host cell already contained many key components that govern eukaryotic cellular complexity.” Thus they had that complexity back then. Not so good for Darwinism unless Darwinism is magic.
