How do we evolve/survive?

At just 10 years old, Jo Nagai conducted an experiment that would surprise scientists around the world.

By raising and training swallowtail caterpillars at home, Jo demonstrated that butterflies can retain memories formed during their larval stage, even after undergoing complete metamorphosis. But what he discovered next was even more unexpected: those learned responses appeared to persist to the next generation.

This video explores Jo’s experiment, the scientific ideas behind it, and the simple question that started it all.
