Woese's progenote hypothesis

Isn't it all quite analogeous to the situation in cosmology?Extrapolation via current physics leads to (explains adequately) Big Bang/Expanding Universe cosmology but breaks down near the "beginning" where physics were wholy different.Extrapolation via current understanding of descent with modification and natural selection leads to (explains adequately) common descent but breaks down near the "beginning" where other processes were going on because 'life' was closer to pure chemistry.What is the problem here? Is cosmology and/or the current understanding of physics maybe total bollocks because of what we don't know for sure yet about the very beginning?

So what? What in the world is so shocking about this? What is so threatening for the whole common descent concept? It is completely expected since no evolution adherent envisions a perfect hereditary mechanism with completely functional DNA and a natural selection 'routine' to just pop out of nothing. There exists necessarily a grey area from simple self-replicating chemicals to the more complex routine that we observe in function now.Again, claiming that it invalidates common descent (not necessarily universal common descent) is not much different from claiming that the expanding universe cosmology is a myth, just because it is acknowledged that our current physics don't hold during the first tentothepowerminusquadrillion seconds.In both cases science is aware of the 'problem', and in both cases it does not affect the validity of the general principles that are observed to be in place from a certain moment onwards.Sure 'special creation' can also fit the data. It would also fit any other possible data, and thus it is useless.

Exactly my point... There's absolutely nothing revolutionary or unexpected about this. Only some sort of special instant creation assumption would make it possible to uphold the current "form of evolution" down to the absolute beginning. Any hypothesis of gradual evolution from simple self-replicating molecules to the kind of life that we see now, will necessarilly go through a phase that can not be anything else but quite different from the current mechanisms. Nothing shocking there.
