OOL researcher David Deamer disputes the new claim. “The mechanism is a far cry, he noted, from the complicated, multistep process by which modern cells divide.” But so? It’s the Narrative, right?
How they got there is apt to be a cause of speculation.
Financial Times: Wealthy investors are offering a $10m prize to the first scientific team that can create a genetic code from simple chemicals.
Well, this is interesting, for sure: “The findings show that this broad class of single-stranded DNA viruses, which infect all three cellular domains of life, have acquired their genetic components through complex evolutionary processes not traceable to a single ancestral event.” Maybe there wasn’t a “single ancestral event” for cells either. Also: The hope is to “resolve the question of how cell-based life came to co-exist with the planet’s staggering array of viruses (dubbed the virome).” One commonly heard hypothesis is that viruses are degraded cells. It will be interesting to hear alternative theses.
The theory has been resurrected in a paper in PNAS, of which Rob Sheldon says, “None of these steps is remotely likely. Not one.”
If there apparently isn’t and never has been life on Mars, why should we assume it exists elsewhere? If there is/has been life on Mars and it looks like it came from Earth, well, that’s a game-changer in itself. If it doesn’t look like it came from Earth, that opens up whole new, *non-speculative* vistas.
He writes, “It is time for a temporary time out. Why not admit what we cannot yet explain: the mass transfer of starting materials to the molecules needed for life; the origin of life’s code; the combinatorial complexities present in any living system; and the precise non-regular assembly of cellular components?”
World famous chemist James Tour explains.
Actually, the researchers are not so dumb when you consider that looking for chance events attracts the grants. Little else would.
Hugh Ross: The discovery of life in another planetary system would indicate another instance of such divine intervention, meaning our universe would contain not just one origin-of-life miracle, but two.
Bring your own snacks and pillow.
Clearly, we have come a long way in thinking up new ways to explore the origin of life problem.
Check out Science Uprising 3. In contemporary culture, we are asked to believe – in an impressive break with observed reality – that the code of life wrote itself: … mainstream studies are funded, some perhaps with tax money, on why so many people don’t “believe in” evolution (as the creation story of materialism). The […]
The history of life keeps changing on us. Much more stasis, much less Darwin. Where will we end up?
