Biofluorescence: A Neon World Hidden in Plain Sight

The video explores biofluorescence, a trait found in various organisms, including fish, amphibians, and even flying squirrels. It explains how fluorescence differs from pigmentation, involving the emission of new light. The evolution of fluorescent proteins is discussed, with theories on convergent evolution and gene transfer. Fluorescence serves various functions, such as camouflage, communication, and UV protection. While plants also fluoresce, it may not always be beneficial. The potential of fluorescence as a bio-signature for detecting life in the universe is also considered.
