Human Evolution News - Human Cultural and Technological Evolution in Northern China, 40,000 Years Ago

Archaeologists Discover Innovative 40,000-Year-Old Culture in China | Max Planck Institute for the Science of Human History

Of course, they never could have guessed it, so the people who were leaving these remains 40,000 years ago would have been oblivious of the fact that their activities as discovered by modern archaeologist, have utterly refuted the ideas that were to emerge in another part of the world some 37,000 years later.

The fact is, however that this is exactly what they have done insofar as the primitive Bronze Age origins myths of a bunch of Middle Eastern nomadic pastoralists and hill farmers are concerned, because these people who made up these camp-fire tales or elaborated on earlier ones, had no inkling that there had been people much like them around in what is now Northern China, some 37,000 years earlier.

The tales these simple people had been handed down had their origins in a part of the world where people believed Earth was very small and only a couple of thousand years old and had been created just for them by magic beings who lived above the sky-dome and who directed the affairs of man.

For these people, the entire world was a circle bounded by the Eastern Mediterranean to the west, the Black Sea and the Caucasus Mountains to the north, the Arabian desert to the south and the flood plains of Mesopotamia and the Iranian Plateau to the east. These were the tales that eventually got written down and incorporated into the state religion of a desperate, increasingly autocratic, dying Roman Empire and are now, almost unbelievably, still regarded as historical truths by some number of people alive today, albeit a decreasing proportion of the developed world's people.

Sadly for these deluded people, evidence of human habitation and cultural/technological progress in Northern China 40,000 years ago, utterly refutes their primitive beliefs which include a global genocidal flood just 6000 years ago, which, had it really happened, would have swept away the archaeological evidence of this culture, as it does the notion that the entire planet has been repopulated by the descendants of a handful of survivors of this flood.

The findings by an international group of archaeologists including scientists from the Chinese Academy of Science and the Max Planck Institute for the Science of Human History, were published recently in Nature. The artifacts are from a period in Eurasian hominin history when Homo sapiens was coming into contact with the Neanderthals and Denisovans, the descendants of an earlier migration by an archaic hominin such as H. erectus, and interbreeding with them and no doubt sharing ideas and technologies.

The main conclusion was that the pattern of finds does not fit in with the idea of a wave of expansion with a fully formed culture and a set of adaptations that fitted them to live in all the different conditions they encountered. Instead, it supports the idea of a process of continual adaptation to the local conditions, adopting and adapting local traditions and technologies as the need arose.

We should expect to see, therefore, a mosaic of innovation patterns with the intermixing of earlier innovations and inventions with persistent local traditions, and the invention of new practices, all taking place in a transitional phase. In other words, cultural and biological co-evolution; a very different thing to that described in the Hebrew Origin myths, where there was little or no record of technological change or cultural development over time.

The accompanying press release from the Max Planck Institute explains the significance of this paper:
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.

Xiamabei stands apart from any other known archaeological site in China, as it possesses a novel set of cultural characteristics at an early date.

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 by 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 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. The finds at Xiamabei are helping us to understand these adaptations and their potential role in human migration.

A new article published in the journal 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 north-eastern 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.

One of the significant cultural features found at Xiamabei is the extensive use of ochre, as shown by artefacts used to process large quantities of pigment. The artefacts 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 impregnated 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
Our findings show that current evolutionary scenarios are too simple, 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.

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 which 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.
