Toe types. Research conducted for the U.S. Army indicated that larger feet may still have smaller arches, toe length, and toe-breadth. The human foot consists of multiple bones and soft tissues which support the weight of the upright human. Specifically, the toes assist the human while walking, providing balance, weight-bearing, and thrust during gait. A sprain or strain to the small interphalangeal joints of the toe is commonly called a stubbed toe. A sprain or strain where the toe joins to the foot is called turf toe. Long-term use of improperly sized shoes can cause misalignment of toes, as well as
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
