Whales able to learn from others
Date:4/25/2013

Humpback whales are able to pass on hunting techniques to each other, just as humans do, new research has found.

A team of researchers, led by the University of St Andrews, has discovered that a new feeding technique has spread to 40 per cent of a humpback whale population.

The findings are published today (Thursday 25 April) by the journal Science.

The community of humpback whales off New England, USA, was forced to find new prey after herring stocks their preferred food - crashed in the early 1980s.

The solution the whales devised hitting the water with their tails while hunting a different prey has now spread through the population by cultural transmission. By 2007, nearly 40 per cent of the population had been seen doing it.

Dr Luke Rendell, lecturer in the School of Biology at the University of St Andrews, said: "Our study really shows how vital cultural transmission is in humpback populations not only do they learn their famous songs from each other, they also learn feeding techniques that allow them to buffer the effects of changing ecology."

The team - also including Jenny Allen from the University of St Andrews, Mason Weinrich of the Whale Center of New England and Will Hoppitt from Anglia Ruskin University - used a new technique called network-based diffusion analysis to demonstrate that the pattern of spread followed the network of social relationships within the population, showing that the new behaviour had spread through cultural transmission, the same process that underlies the diversity of human culture.

The data were collected by naturalist observers aboard the many whale-watching vessels that patrol the waters of the Gulf of Maine each summer.

Dr Hoppitt said: "We can learn more about the forces that drive the evolution of culture by looking outside our own ancestral lineage and studying the occurrence of similar attributes in groups that have evolved in a
