Our species name is Homo sapiens. We share the Order Primates with various other animals, such as chimpanzees, gorillas, monkeys, lemurs and a few others.Our Classcontains all animals with hair including horses, bats, seals, dogs, cats, mice, deer and many others. At the level of our Phylumthe cast is larger and includes birds, amphibians, fish and reptiles and some lesser known animals.
