- Whale calls reveal cultural evolution
Scientists observed sperm whales in the Mediterranean developing a distinct vocal dialect over 20 years, with groups near the Hellenic Trench off Crete using a faster version of a coda while occasionally reverting to an older dialect. The study highlights cultural evolution in real time and suggests a west-to-east population spread of sperm whales in the region.
