A University of Queensland-led study has found humpback whales can learn incredibly complex songs from whales from other regions.

The study looked closely at the song patterns of male humpback whales from each region between 2009 and 2015, to examine how culture transmits between the populations. Dr Allen said the complexity of the songs was determined by measuring ...
