Chinese scientists have discovered dozens of human fossils dating back 300,000 years, which are the earliest ones found in East Asia in terms of the evolution process towards Homo sapiens, the species to which all modern human beings belong.
The human fossils, along with a large number of fossilized animal bones and stone tools, have been unearthed at the Hualongdong site in Dongzhi County, east China’s Anhui Province.
Chinese researchers reported their latest discoveries and studies concerning the Hualongdong ancient human site at an academic conference held in Dongzhi County from Friday to Sunday this week. Nearly 100 researchers and scholars, including over a dozen international experts, attended the event.
Discovered in late 1988, the Hualongdong site has yielded remarkable findings during continuous excavations since 2013. Approximately 20 individual ancient human fossils, including a relatively complete skull, over 400 stone artifacts, numerous bone fragments with evidence of artificial cutting and chopping, and more than 80 vertebrate fossils have been unearthed at this site.
From April to November 2024, an archaeological team conducted a new round of excavations, covering an area of 40 square meters. A total of 11 human fossils were unearthed, including one well-preserved foot metatarsal bone, one broken frontal bone, one middle femur fragment and eight skull fragments.
Wu Xiujie, a researcher at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences (CAS), and leader of the Hualongdong excavation team, said these discoveries show that a large family of more than 20 individuals lived at the site.
“They had a ‘dining hall’ where they cut, chopped and processed food. A karst cave was probably their bedroom for hiding from wild beasts at night, but it has collapsed and we have not yet excavated it. We hope to discover more fossils in the future,” Wu added.
She also explained that the human fossils at Huanlongdong belong to ancient humans with physical characteristics between the Homo erectus and modern human stages – which is unlike any other premodern human fossil ever found.
A skull fossil unearthed in 2015 is one of the most important discoveries made at Hualongdong to date. Researchers inferred that the skull belonged to a girl of 13 or 14 years old.
“The fossil displays a unique blend of primitive and modern characteristics,” Wu noted. “The facial structure and mandible show early evolution toward modern humans, including a flat face, high eye sockets, slender skull, and a jawbone that displays the early development of a chin – a defining feature of modern humans.”
“She already looked very similar to us, but still retained some ancient features,” Wu said.
The foot metatarsal bone found this year is the only one unearthed in China, and it could provide important information in studying both how the ancients walked and their height, Wu said.
In addition, the finely crafted stone tools found at Hualongdong show the relatively high technical level of the Hualongdong cave people 300,000 years ago. They were very intelligent, and had evolved towards the stage of Homo sapiens, according to Wu.
“The Hualongdong humans were the earliest ancient humans in East Asia who exhibited the most characteristics of Homo sapiens and were at a key turning point in the evolution from ancient humans towards modern humans. The Hualongdong site will provide a wealth of information on how modern humans evolved,” said Liu Wu, another researcher with the IVPP, who has conducted excavations at the site for more than a decade.
