Note that cultural transmission of humpback whale song is well-known and studied. Here's an example article on movement of songs across Pacific ocean populations in the span of ~2 years: https://royalsocietypublishing.org/doi/epdf/10.1098/rsos.220158 https://royalsocietypublishing.org/doi/epdf/10.1098/rsos.220... (ed - in other words, cultural transmission of humpback whale song isn't part of the claims of the paper. The result is the Zipf distribution, and they hypothesize that the Zipf-law is emerging because of the cultural component.)
