Abstract

 Every human being is proficient in face recognition. However,the reason for and the manner in which humans have attained such an ability remain unknown. These questions can be best answered-through comparative studies of face recognition in non-human animals. Studies in both primates and non-primates show that not only primates,but also non-primates possess the ability to extract information from their conspecifics and from human experimenters. Neural specialization for face recognition is shared with mammals in distant taxa,suggesting that face recognition evolved earlier than the emergence of mammals. A recent study indicated that a social insect,the golden paper wasp,can distinguish their conspecific faces,whereas a closely related species,which has a less complex social lifestyle with just one queen ruling a nest of underlings,did not show strong face recognition for their conspecifics. Social complexity and the need to differentiate between one another likely led humans to evolve their face recognition abilities.
