Scientists Create Molecules that can Follow Darwinian Evolution - by PaulMattSutter
that is capable of self-reproduction and is subject to Darwinian evolution. By storing information, interacting with its environment, and making copies of itself, life can do all the interesting things that life likes to do, and evolve into more efficient processes that continue doing those things.Speaking very broadly, modern life uses three sets of molecules to accomplish the business of being alive. DNA stores the information and generates RNA.
However, scientists have had difficulty finding which RNA sequences might survive in the harsh conditions of the early Earth. But the University of Tokyo researchers have found something interesting, according to“We found that the single RNA species evolved into a complex replication system: a replicator network comprising five types of RNAs with diverse interactions, supporting the plausibility of a long-envisioned evolutionary transition scenario,” said Mizuuchi.
This was the first time that a laboratory experiment found a set of RNA molecules that could do all the basic functions required for life.
