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.
A researcher from the National Research Tomsk State University devised a new "sniff test" that proves man's best friend is actually self-aware.
Can certain species of fish – especially specias that all seem to look alike – distinguish between friend from a foe? Apparantly so, say surprised reaserchers who say recongition comes down to small but distinct facial coloring patterns.
