Accessory nail of the fifth toe Accessory nail of the fifth toe The accessory nail of the fifth toe is a physical trait of the small toe, where a minuscule "sixth toenail" is present in the outer corner of the nail situated on the smallest toe. The trait can be observed on either one or both feet, where there is a separation of the toenail situated on the smallest toe. The separated part of the nail forms a smaller "sixth toenail" on the corner of the larger, or "main" section of the toenail, on the outermost side of the foot, which protrudes outwards from the corner
Names for the human species "Homo", e.g. "Homo paniscus", "Homo sylvestris", or "Homo arboreus". An alternative philosophy suggests that the term "Homo sapiens" is the misnomer and that humans should be reclassified as "Pan sapiens". In either case, a name change of the genus would have implications on the taxonomy of extinct species closely related to humans, including "Australopithecus". A taxonomic name given to the species of the last common ancestors of humans and chimpanzees is "Pan prior". The following names mimick binomial nomenclature, mostly consisting of "Homo" followed by a Latin adjective characterizing human nature. Most of them were coined since the mid 20th
