Mumbai: Research has proved that humans have the largest penises in the primate world.
According to a report in the Daily Mail, human penis may have grown so long in order to attract potential partner. In addition to this, it also serves as a mean to keeping the body cool.
Evolutionary biologist, Professor Darren Curnoe said, ‘Amazingly the size of the reproductive organs, especially the testicles, are a reflection of how the apes are organised socially.’
