The Sea Slug That Looks Like A Sesame Seed

追加: 2026-06-03

[00:00:00]One in every five animals in the sea has a shell it did not make. For a century, taxonomy meant the eye. A human looked at a speckled translucent body the size of a rice grain under a microscope. The eye saw a slug. The eye could not see the difference. The old approach could not read the animal. A machine scanned the slug's DNA. Not the shape, not the color, the sequence. It matched the sequence against every known mollusk genome. The match was not there. The AI returned a new branch on the tree, a species no human had ever named. The slug was discovered in Taiwanese tide pools. The AI had already seen what the eye could not. The machine now knows millions of such sequences. It is not waiting for the eye to catch up.
