A new study has dated South Africa’s famous Taung Child fossil to about 3 million years ago, raising questions about how early human species evolved and lived alongside one another.
Published in npj Palaeoecosystems, the research estimates that the fossil is between 2.96 million and 3.03 million years old. The findings suggest that southern Africa may have supported more early human species than scientists previously believed. Professor Gabriele Macho of Vrije Universiteit Brussel in Belgium led the international research team.
Taung Child fossil challenges century-old assumptions
Discovered in South Africa in 1924, the Taung Child transformed scientific understanding of human origins. The fossil provided important early evidence that human ancestors evolved in Africa, challenging widely accepted theories at the time.
The discovery helped establish Africa’s central role in human evolution, a subject that continues to attract attention as new fossil discoveries raise questions about the origins of early human ancestors. The specimen became the defining example of Australopithecus africanus, an extinct early human relative. However, researchers say scientists never established clear criteria for assigning other fossils to the same species.
Fossil comparisons suggest multiple early human species
Researchers examined tooth structure, dental growth, and brain development patterns. Their comparisons revealed differences between the Taung Child and adult fossils traditionally placed in the same species. The findings suggest that fossils from the Sterkfontein region may represent several distinct early human species that lived during the same period or at different times.

Previous research has also revised the ages of Australopithecus fossils from the Sterkfontein caves, highlighting the region’s importance in understanding human evolution.
Ancient climate shifts may explain early human diversity
Researchers believe shifting climate conditions helped drive this diversity. Millions of years ago, southern Africa experienced repeated wet and dry periods that changed its landscape. As habitats expanded and shrank, early human populations may have become separated before re-establishing contact. Researchers suggest these encounters could have encouraged interbreeding and adaptation.
Other discoveries have also revealed how different early human species followed separate evolutionary paths in South Africa. Fossilized pollen provides further clues about the Taung Child’s ancient environment. The evidence suggests that the region once supported wetter conditions and more trees than it does today.
Some of the identified tree species now grow hundreds of kilometers northeast of the fossil site. This points to major environmental changes over millions of years.
New dating evidence reshapes human evolutionary history
Researchers estimated the fossil’s age using geological evidence, including the dating of a mineral layer above the fossil-bearing deposits. The findings challenge the traditional view of human evolution as a simple progression from one species to another. Instead, researchers suggest that changing environments helped shape a complex history of early human populations.
More recent fossil discoveries in Morocco have also offered clues about the evolutionary history of the human lineage. A century after its discovery, the Taung Child continues to offer new evidence about the origins and diversity of ancient human relatives.
