Body ( Aristotle ) : The physical or material frame or structure of humans or any other animal; the whole material organism viewed as an organic entity. Aristotle used the term in this sense; see translation by Thompson (1910, Book 1), also see Oxford English Dictionary (1989, definition 1). All bodies have an age in the life cycle and a sex (female, male, mixed). In taxonomy, only the physical characteristics common to a taxon (like species) are considered, not the variable physical characteristics of individuals; see Simpson (1961, p. 18).
