Dumont and Rifkind recently proposed that the New World monkey, the sloth and the bat have evolved only a rudimentary form of thoracic duct because these animals hang upside down from trees1. Whether or not this proposition is correct, it seems to me that the authors have reached their interesting conclusion by a devious and sometimes misleading argument.
