AI Has Successfully Imitated Human Evolution—and Might Do It Even Better
Artificial intelligence is a master of imitation. Every time scientists design an AI—whether to mimic human language or master a game like chess—it either matches or far exceeds the capabilities of its biological creators. Now, AI has proven that it can even master the art of biology itself.
Researchers at the University of California-San Francisco, the University of California-Berkeley, and Salesforce Research, a science arm of the SF-based software company, developed an AI capable of copying evolution itself. This doesn’t mean the AI created some sort of evolutionary superior superhuman (yet), but instead, the AI designed sequences of 20 amino acids that make up proteins. When compared to nature’s handiwork, some of the sequences worked just as well as ones generated over millions of years of evolution. The researchers published their findings in the journal Nature Biotechnology.
Interestingly, scientists didn’t design an AI from scratch, but rather, repurposed one from an unlikely field: a language model. Researchers used Salesforce’s ProGen natural language-processing abilities and focused on the “sentences” of biological proteins—essentially a language of amino acids.
“In the same way that words are strung together one-by-one to form text sentences, amino acids are strung together one-by-one to make proteins,” Nikhil Naik, the Director of AI Research at Salesforce Research, told Motherboard.“Building on this insight, we apply neural language modeling to proteins for generating realistic, yet novel protein sequences.”
