Origin of Life Problem Solved

This event is believed to have taken place possibly 4billion years ago, at a time when a young earth was a hostile place with a volcanic activity and an atmosphere that had yet to contain oxygen. RNA, said Durand, was hardy and would have survived these kinds of conditions.

"This probably would have happened along the shoreline, in pools of water, although some people believe it might have even happened on clay," Durand said.

Francis Thackeray, of the Institute for Human Evolution at Wits, said that surprisingly what Durand and Dhar had discovered was suggested by Charles Darwin 146 years ago.

The article doesn't live up to the title. At all. As is usual for shitty popular-press articles. :coffee:

Indeed, it's but one piece in the puzzle - how to develop larger self-replicating and self-ligating RNAs from smaller units.

I thought most of the relevant scientists were thinking more along the lines of life starting around something like those Deep Sea Hydrothermal Vents, the black and white smokers at the mid-ocean ridges? There's a ton of energy available and no UV to worry about.

A somewhat related question, is it generally thought that there is more biomass in rock than on the surface and in oceans? It's been found pretty deep, like over a kilometer, maybe over 2-3 Km, and everywhere, if I remember correctly.

As snappy as the title is,

Molecular trade-offs in RNA ligases affected the modular emergence of complex ribozymes at the origin of life


...might not grab the public imagination.

Just my opinion though.

Maybe the public should focus less on imagination and more on facts and knowledge. It's 2017, ffs.

Sure, but the popular press is less interested in science than in selling copy, by appealling to the public's imagination.
