Cultural Outreach: & # 39; Humpback Whales Learn New Songs Every Year (VIDEO)

Humpback whales, known for the sound, sound, and song pattern sing the songs for a few years, before they welcome them to make them harder. However, according to the research of the University of Queensland, after a few years, the whales change to simpler, simpler simplification, and show the ability to learn new materials.

The study, published on November 21 in the Proceedings magazine at the Royal Society B: Bio-Science Sciences, & # 39; Exploring the structure and complexity of songs taken by Australian flagship numbers of Australia for 13 years after each other. The crude whale songs were recorded annually from 2002 to 2014 on the south east coast of Queensland, Australia, using fixed wooden assaults, devolution records and boat-based recordings.

The researchers found that although the songs changed to gradually sing the whales each year, the whole of the whales replaced their songs with new ones – a few years in which researchers are called "cultural outreach".

Improved harmonization when songs came forward, followed more songs with more audio units, unit types and themes. After expansion, complexity decreased so that newer songs would be shorter and fewer units, units of units and subjects, "said the inspection.

"Usually, change these songs gradually, & maybe by singing singers," said Dr. Jenny Allen of the Cetacean Ecology and Acoustics Laboratory, Queensland University, is the main author of the report in the university press release on November 22.

"We believe that the authors allow a bull to stand out of their peers, very similar to teenagers who try to stand up, out of the crowd. But every few years the songs will be replaced – somewhat simpler – always suggest that the ability of the whales to learn new material, "explained Allen.

The study is a good model for cultural learning in animals, and Allen noted it, saying that the crude whale songs are spread over animal numbers and basins.

"This is a cultural subtraction on a scale that is similar to what we find in humans," she said.

"By learning more about culture and social learning in animal species such as solid whales, we can better understand what has evolved, and what is the patient's value. By & Responding to these questions in animals, we may be able to clarify why cultural and social development has become so special in humans, "she said.

Allen did not respond promptly to Sputnik's request for comment
