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.
