Notes on verification

Multiple independent, high-quality sources (National Geographic, Live Science, Science.org, CBC, Wikipedia) corroborate that Little Foot is classified as distinct from Australopithecus afarensis (Lucy's species), though the exact species designation (africanus, prometheus, or unnamed) remains debated among researchers.
