Male humpback whales go through a "cultural revolution" every few years, change the song 1 NEWS NOW


According to new research, populations of male humpback whales undergo a "cultural revolution" every few years when they change their song hymn.

A 13-year study by experts from the University of St Andrews and the University of Queensland in Australia concerned 95 humpbacks from eastern Australia, reports from the BBC.

They discovered that when a revolution occurs, a new song is always simpler than the previous one. They also found evidence that gradual changes to the song were caused by new sounds introduced by other whales, which were later learned by the rest of the group.

Humpback whales are famous for having "unique dialects" for different populations.

Groups of male whales have their own "hymns", and each member of the population sings the same sequence of the same sounds.
