When did populations of Homo sapiens first arrive in China and what happened when they encountered the Denisovans or Neanderthals who lived there? A new study in Nature by an international team of researchers opens a window into hunter-gatherer lifestyles 40,000 years ago. Archaeological excavations at the site of Xiamabei in the Nihewan Basin of northern China have revealed the presence of innovative behaviors and unique toolkits.
The discovery of a new culture suggests processes of innovation and cultural diversification occurring in Eastern Asia during a period of genetic and cultural hybridization. Although previous studies have established that Homo sapiens arrived in northern Asia about 40,000 years ago, much about the lives and cultural adaptations of these early peoples, and their possible interactions with archaic groups, remains unknown. In the search for answers, the Nihewan Basin in northern China, with a wealth of archaeological sites ranging in age from 2 million to 10,000 years ago, provides one of the best opportunities for understanding the evolution of cultural behavior in northeastern Asia.
The article published in Nature describes a unique 40,000-year-old culture at the site of Xiamabei in the Nihewan Basin. With the earliest known evidence of ochre processing in Eastern Asia and a set of distinct blade-like stone tools, Xiamabei contains cultural expressions and features that are unique or exceedingly rare in northeastern Asia. Through the collaboration of an international team of scholars, analysis of the finds offers important new insights into cultural innovation during the expansion of Homo sapiens populations.
“Xiamabei stands apart from any other known archaeological site in China, as it possesses a novel set of cultural characteristics at an early date,” says Dr. Fa-Gang Wang of the Hebei Provincial Institute of Cultural Relics and Archaeology, whose team first excavated the site.
Cultural adaptations at Xiamabei
“The ability of hominins to live in northern latitudes, with cold and highly seasonal environments, was likely facilitated by the evolution of culture in the form of economic, social and symbolic adaptations,” says Dr. Shixia Yang, researcher with the Chinese Academy of Sciences and the Max Planck Institute for the Science of Human History, in Jena, Germany. “The finds at Xiamabei are helping us to understand these adaptations and their potential role in human migration.”

One of the significant cultural features found at Xiamabei is the extensive use of ochre, as shown by artifacts used to process large quantities of pigment. The artifacts include two pieces of ochre with different mineral compositions and an elongated limestone slab with smoothed areas bearing ochre stains, all on a surface of red-stained sediment. Analysis by researchers from the University of Bordeaux, led by Prof. Francesco d’Errico, indicates that different types of ochre were brought to Xiamabei and processed through pounding and abrasion to produce powders of different color and consistency, the use of which stained the habitation floor. Ochre production at Xiamabei represents the earliest known example of this practice in Eastern Asia.
The stone tools at Xiamabei represent a novel cultural adaptation for northern China 40,000 years ago. Because little is known about stone tool industries in Eastern Asia until microblades became the dominant technology about 29,000 years ago, the Xiamabei finds provide important insights into toolmaking industries during a key transition period. The blade-like stone tools at Xiamabei were unique for the region, with the large majority of tools being miniaturized, more than half measuring less than 20 millimeters. Seven of the stone tools showed clear evidence of hafting to a handle, and functional and residue analysis suggests tools were used for boring, hide scraping, whittling plant material and cutting soft animal matter. The site inhabitants made hafted and multipurpose tools, demonstrative of a complex technical system for transforming raw materials not seen at older or slightly younger sites.
A complex history of innovation
The record emerging from Eastern Asia shows that a variety of adaptations were taking place as modern humans entered the region roughly 40,000 years ago. Although no hominin remains were found at Xiamabei, the presence of modern human fossils at the contemporary site of Tianyuandong and the slightly younger sites of Salkhit and Zhoukoudian Upper Cave, suggests that the visitors to Xiamabei were Homo sapiens. A varied lithic technology and the presence of some innovations—such as hafted tools and ochre processing, but not other innovations, such as formal bone tools or ornaments—may reflect an early colonization attempt by modern humans. This colonization period may have included genetic and cultural exchanges with archaic groups, such as the Denisovans, before ultimately being replaced by later waves of Homo sapiens using microblade technologies.

Given the unique nature of Xiamabei, the authors of the new paper argue that the archaeological record does not fit with the idea of continuous cultural innovation, or of a fully formed set of adaptations that enabled early humans to expand out of Africa and around the world. Instead, the authors argue that we should expect to find a mosaic of innovation patterns, with the spread of earlier innovations, the persistence of local traditions, and the local invention of new practices all taking place in a transitional phase.
“Our findings show that current evolutionary scenarios are too simple,” says Professor Michael Petraglia of the Max Planck Institute in Jena, “and that modern humans, and our culture, emerged through repeated but differing episodes of genetic and social exchanges over large geographic areas, rather than as a single, rapid dispersal wave across Asia.”

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.
Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.
She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.
Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.
“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.
It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.
Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.
Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.
Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.
“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.
He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.
Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.
TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.
Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.
Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.
The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.
The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.
It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.
Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.
Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.
Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.
Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.
Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.
The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.
Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”
Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.
“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.
B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.
Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.
Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.
Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.
“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”
Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”
“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.
Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.
“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
This report by The Canadian Press was first published Sept. 9, 2024.
