Mock Rock band Spinal Tap probably never expected that the lyrics of their song 'Big Bottom' would be the subject of a science paper, but its true.
The song - which deals with how much more sexually satisfying a large bottom on a woman can be - has been the corner stone of studies into trends in sexual diversity amongst the animal kingdom.
Scientists concluded that large bottoms are in fact 'sweeter' for the 'pushin'. They studied the mating habits of baboons and discover that females with huge arse were twice as likely to attract male attention than those with more svelte physiques.
Members of Spinal Tap reacted favourably to the results.
Nigel Tufnell said it was "Cool, yeah, man", while David St Hubbins wanted to see photographs of what the 'baboon chicks ass was like'.
