Quadrumana (Quadrumana and Bimana form an obsolete division of the primates: the Quadrumana are primates with four hands (two attached to the arms and two attached to the legs), and the Bimana being those with two hands and two feet. The attempted division of "Quadrumana" from "Bimana" form a stage in the long campaign to find a secure way of distinguishing Homo sapiens from the rest of the great apes ... Quadrumana is Latin for "four-handed ones", which is a term used for apes since they do not have feet attached to their legs as humans do, but instead have hands, as both pairs of hands look almost alike (with the exception of the orangutan, whose hands look exactly the same) and operate exactly like hands. Bimana is Latin for "two-handed ones", which is a term used for humans, as humans have only two hands, but have two feet which apes do not.)
