New glowing molecule, invented by AI, would have taken 500 million years to evolve in nature

An artificial intelligence (AI) model has simulated half a billion years of molecular evolution to create the code for a previously unknown protein, according to a new study. The glowing protein, which is similar to those found in jellyfish and corals, may help in the development of new medicines, researchers say.

The sequence of letters that spell out the instructions to make esmGFP is only 58% similar to the closest known fluorescent protein, which is a human-modified version of a protein found in bubble-tip sea anemones (Entacmaea quadricolor) — colorful sea creatures that look like they have bubbles on the ends of their tentacles. The rest of the sequence is unique, and would require a total of 96 different genetic mutations to evolve. These changes would have taken more than 500 million years to evolve naturally, according to the study.
