Right handedness and survival

The whole issue of handedness has always interested me, perhaps because I am lefthanded. The findings of a recent article combine a large number of studies and propose that handedness is a common occurance in various species.

A recent article in Science Daily explore the issue of handedness and conclude that right handedness provide animals the ability to multitask specific feeding activities with predator monitoring. Chicks who have developed in the dark lose this brain lateralising behaviour and are quite good at picking seeds from pebbles until they have to monitor for predators. Then they do a poor job of both.
