New glowing molecule, invented by AI, would have taken 500 million years to evolve in nature, scientists say
An artificial intelligence model has created a new protein that researchers say would have taken 500 million years to evolve in nature — if nature were capable of producing such a thing.
"We've found that ESM3 learns fundamental biology, and can generate functional proteins outside the space explored by evolution," study co-author Alex Rives, co-founder and chief scientist of EvolutionaryScale, told Live Science in an email. However, she also noted that the researchers' claim of simulating 500 million years of evolution is focussed only on individual proteins and does not account for the many stages of natural selection that ultimately create life. "AI-driven protein engineering is intriguing, but I can't help feeling we might be overly confident in assuming we can outsmart the intricate processes honed by millions of years of natural selection," Taylor said.
