"Zinj" is an ancient Arabic word for the East African coast; "anthropus" refers to the fossil's humanlike characteristics; and "boisei" refers to Charles Watson Boise, who had been making financial contributions to the Leakeys' work since 1948.This classification was eventually revised to "Paranthropus boisei", though this remains a matter of contention since the genus "Paranthropus" is disputed because of morphological similarities to "Australopithecus".
