Scientists in the Natural History Museum have aided date the Broken Hill skull, a key ancient human found Africa from the 1920s.

The study headed by Professor Rainer Grün in the Griffith University, Australia, estimates the skull is involving 274,000 and 324,000 years old, which is a lot younger than previously believed.

Scientists in the Natural History Museum have aided date the Broken Hill skull, a key ancient human found Africa from the 1920s. The study headed by Professor Rainer Grün in the Griffith University, Australia, estimates the skull is involving 274,000 and 324,000 years old, which is a lot younger than previously believed.

Discovered at 1921 from miners at Zambia, that the Broken Hill skull is among the best-preserved fossils of the ancient human species Homo heidelbergensis and has been estimated to be approximately 500,000 years old. The fossil was contributed to the Natural History Museum at the 1920s and is presently on screen in the Museum’s Human Evolution gallery.

Due into the chance discovery of the remains and the subsequent destruction of the first website by mining, historically it’s been rather tricky to ascertain the age of their skull. The study group employed radiometric dating methods on the skull and substance recovered close to the cranium, in addition to other finds from the website. The researchers also used sediment scraped right from the skull at the 1920therefore, which was discovered from the collections of those Natural History Museum.

The Natural History Museum’therefore Professor Chris Stringer stated: “Through years of painstaking work for example direct relationship of the skull and other substances located around the Broken Hill website, I, geochronologist Rainer Grün, along with other colleagues have generated a best age estimate of approximately 299,000 years to its Broken Hill skull. This is amazingly youthful, as a fossil about 300,000 years will be anticipated to show intermediate characteristics between H. heidelbergensis and H. sapiens, however Broken Hill reveals no substantial attributes of our species”.

The research also indicates that human development Africa about 300,000 years back was a far more intricate procedure, together with the co-existence of distinct human lineages.

Professor Stringer proceeds: “Previously, that the Broken Hill skull has been seen as a member of a slow and prevalent evolutionary sequence in Africa from primitive humans to modern people. But today it seems as though the primitive species Homo naledi lived in southern Africa, H. heidelbergensis was in south-central Africa, and ancient types of those species existed in areas like Morocco and Ethiopia”.
