(PhysOrg.com) -- According to Oxford University's professor of evolutionary anthropology, Robin Dunbar, after you have amassed 150 friends on Facebook, any more are meaningless because the human brain can only remember 150 meaningful relationships anyway. Professor Dunbar says this number applies to different societies and has remained unchanged throughout history.
