As a biology student I can tell you that you are most likely correct :-)<p>Behavioural studies in animals are a fascinating field. I can&#x27;t back it up with citations right now, but I&#x27;m pretty sure horses and dogs are not the only animals to read human facial expressions. Chimps, cats, parrots - you name it - if it&#x27;s been in close contact with humans for any length of time, I wouldn&#x27;t be surprised if it learnt how to read our emotions.
