For nearly a century, scientists have been puzzling over fossils from a strange and robust-looking distant relative of early humans: Paranthropus robustus. It walked upright, and was built for heavy chewing with relatively massive jaws, and huge teeth with thick dental enamel. It’s thought to have lived between 2.25 million and 1.7 million years ago.
Humans today have a diverse array of hominin distant relatives and ancestors from millions of years ago. The South African fossil record ranges from early hominins such as Australopithecus prometheus, A. africanus (Taung child), A. sediba and P. robustus, to early members of the genus Homo (H. erectus/ergaster, H. habilis), to later hominins such as H. naledi and Homo sapiens (humans).
Fossils show how these early relatives evolved from as far back as A. africanus, 3.67 million years ago. They also document milestones in evolution, including the transition to walking on two legs, tool making and increased brain development. Ultimately, our species – Homo sapiens – appeared in South Africa 153,000 years ago.
