A five-year digital reconstruction of the 3.7 million-year-old face from South Africa's Sterkfontein Caves revealed features resembling eastern African Australopithecus fossils.
The skull, damaged after burial for about 3.67 million years, was digitally reassembled, but researchers say one specimen cannot yet confirm a new species.
Scientists plan to reconstruct more of the skull, especially the cranium, to clarify Little Foot's age, species classification and implications for early human and brain evolution.
Could this 3.7-million-year-old face, just revealed by technology, belong to an entirely new human ancestor?
What secrets of our brain's evolution might be unlocked next from this 3.7-million-year-old skull?
Little Foot Redefined: Evidence for a New 3.67-Million-Year-Old Hominin Species
Overview
In 2026, Dr. Jesse Martin and his team published a landmark study re-analyzing the nearly 3.67-million-year-old Little Foot skeleton, identifying unique anatomical features that clearly differentiate it from Australopithecus africanus and Australopithecus prometheus. These differences led researchers to conclude that Little Foot represents a new hominin species. After resolving previous dating controversies, a consensus now places Little Foot as one of the oldest hominins in southern Africa. This older age and distinct species status reveal that multiple hominin species coexisted around 3.67 million years ago, challenging linear evolution models and supporting a branching tree of human ancestry. Future research will focus on formally naming the species and exploring its ecology, locomotion, and evolutionary relationships.
