Live Science weekend news roundup

Little Foot is a near-complete Australopithecus skeleton — the most complete ever discovered — from South Africa. Researchers first unveiled the small ancient human in 2017, but precisely where it sits on our family tree has been the subject of scientific debate.

Some have proposed that Little Foot is a previously unknown species and should be given the name Australopithecus prometheus. However, A. prometheus is a recycled name that was initially meant for another South African fossil discovered in 1948, but fell out of favour after researchers decided that the fossil was likely from the known species Australopithecus africanus. Another possibility was that Little Foot was also A. africanus.

The new claims derive from a study published last month in the American Journal of Biological Anthropology. Here, the research team argues that neither A. prometheus nor A. africanus is an appropriate classification for Little Foot.

The classification of human fossils is often contested, so I’m keen to see how other anthropologists react to the new study and will follow up with more information as it emerges.
