Interesting new PNAS paper casts doubt on universal common ancestry

Universal common ancestry was a religion, really. Create a religion, birth a heretic…

Evolution Intelligent Design Origin Of Life

At BiorXiv: LUCA (Last Universal Common Ancestor) more complex than supposed

Note that last sentence: “Our results depict LUCA as likely to be a far more complex cell than has previously been proposed, challenging the evolutionary model of increased complexity through time in prokaryotes. Given current estimates for the emergence of LUCA we suggest that early life very rapidly evolved considerable cellular complexity.” Just an accident. Nothing to see here.
