Voles are apparently impressed by the size of their personal equipment and don't really care if most of it is hardly used.
The Vole, of which the largest specimen was dug up in Redmond, sees the secret to success based on the size of their interface, according to scientists.
Boffins from Europe who were studying Volish interface to see how it managed to spread out through out the world and destroy other eco-systems so well.
According to Behavioural Ecology and Sociobiology, which we get for the "spot the todger" competition, found dominant Voles have wider penis bones, called baculum. They are also renowned for their unusual vocal behaviour and unusual dance steps.
A study of Volish equipment was conducted by Dr Jean-Francois Lemaitre from the University of Liverpool with colleagues in France and Switzerland.
Apparently such bones are not found in humans and no-one knows what the Vole uses them for. They are trident-shaped with a wide base, which sounds like it would make a Lady Vole's eyes water. Voles live for a maximum of 18 months and females give birth to four or five litters per year often shagging several different males in one go. A recent court case showed that this was normal volish behaviour during a sales conference.
Researchers think that competition has caused voles to develop larger todgers to improve males' chances of reproduction.
They collected wild voles from the UK and devided them between management and subordinate.
Pairs of males were then exposed to nesting material from a female and the scent mark patterns they made were recorded.
Those that had the strongest scent marks were classified as dominant and made more attempts to attract the female. Apparently it was not the length, but the width that attracted the lady voles.
The theory is that female voles require physical stimulation to release eggs, wider baculum bones may achieve this more often, leading to greater reproductive success.
