Scientists have found the impact of tickling in animals

Researchers conducted a study to learn how animals react to tickling.

An employee of the reserve for the animals in the county of Kent, Phil Regis found that 19 -year-old gorilla, Amy can not resist a happy snorting when she tickled. In addition, Regis said he had not once seen as a gorilla in the game tickle each other.
In a study published in the journal Current Biology, researchers compared the sounds of apes when they are tickled with human laughter, reports BBC BBC.
It was noted a lot of acoustic parallels that led to the conclusion that apes the evolutionary source of laughter equal to men, and it probably indicates a common ancestor, who laughed when tickled.
A few years ago Dzhaak Panksepp, who works now in the College of Veterinary Medicine at the University of Washington, decided to find out how rats respond to tickling.
The researchers found that rodents with high- tickling emit a squeak, not perceived by the human ear. The same sounds rats published by playing with other rats.
The scientist claims that an increasing number of animal behavior researchers are turning to the internet, because there they have access to a huge number of amateur videos, which are then categorized and analyzed.
Quick search finds a large number of animals - such as owls, dogs, meerkats, penguins, and even camels and dolphins that make sounds when tickled.
