When can we say AI made a scientific discovery?

In September 2026, Anthropic, an AI company, announced that its AI system, called Claude, had made a discovery in molecular biology.

The system operates within a lab where 950 AI agents analyze vast databases of DNA sequences to identify patterns that might lead to scientific breakthroughs.

For example, these agents might flag unusual sequences that could encode enzymes with useful properties.

Anthropic claimed that after 21 hours of analysis, the AI identified a repeating pattern around a known enzyme, a pattern Anthropic stated had not been catalogued before.

This pattern was described as being reminiscent of the structure that led to CRISPR, a revolutionary gene-editing technology.

However, the announcement sparked debate about whether this constituted a genuine scientific discovery or merely an assistive tool for human scientists.
