Chimpanzees Recognize Each Other Through Their Butts

Scientists have discovered that chimpanzees have an interesting ability to recognize not only faces but also each other's butts. The talents and abilities of many primate species have been measured by how well they are able to perform human skills. However, this new finding is a skill that not many humans can and will do. Though face recognition has been recorded, tested, and studied in animals for a very long time, this is one of the first major breakthroughs about it.
