WHAT DID NEANDERTHA­LS MAKE?

We know that the Neandertha­ls were talented makers. They used a sophistica­ted array of scrapers and blades, which they fashioned out of stone and other materials. And though Neandertha­ls were once portrayed as basic and brutish, scientists are now stressing a new narrative: This species was in its way as innovative and creative as our own ancestors. Here’s a look at what Neandertha­ls could make.

STONE TOOLS: It’s no secret that Neandertha­ls fashioned sophistica­ted stone “flakes,” tools with flat faces and thin, sharp sides. To form these flakes, they selected small chunks of stone, also called cores, and trimmed their sides until they took the shape of tortoise shells — flat on one

side and spherical on the other. They then smashed the tops of the trimmed stones with a single blow, spitting out sharpened flakes of a standard shape and size, perfect for cutting, carving, and scraping.

Studies say that the toolmaking practices associated with the Neandertha­ls

included the shaping of over 60 forms of flakes, all fit for specific functions. And though the species wielded some of these tools without any additional shaping and sharpening, they also modified many others into more sophistica­ted, more specialize­d implements, including saws and spear points. Some Neandertha­l tools were actually set into handles and secured with ties and adhesives.

BONE TOOLS: Sharpened stones weren’t alone in the Neandertha­l toolbox. A 2023 study in PLOS ONE found that Neandertha­ls also fashioned implements out of bone, once seen as a solely H. sapiens skill, for the purpose of butchering animals and preparing hides. Evidence for this has arisen from several Neandertha­l sites of note, such as the Chagyrskav­a Cave in the Altai Mountains in Siberia, where about 1,200 bone tools were recently revealed. Researcher­s theorize that some 50,000 to 60,000 years ago, Neandertha­ls used the site to process a wide range of animals, including reindeer, horses, and bison, during the cold season.

As they cleaned off bones harvested from the large-hoofed animals, Neandertha­ls fashioned them into tools, including a large number of retouchers, to sharpen or shape stone implements, and at least one rounded tool similar to a present-day leatherwor­king instrument. This would have come in handy while processing hides.

CLOTHING: The creation of tools for preparing and piercing holes in hides indicates, according to some studies, that the Neandertha­ls made clothing. Adding to this assertion are recent finds of Neandertha­l fiber technology. In 2020, researcher­s published a paper in Scientific Reports about a single strand of twisted tree frass from a Neandertha­l site in France. Though the 50,000-year-old strand only amounts to a three-ply tangle of fibers, the team says that the twine may indicate a broader industry of string-making. “Twisted fibers provide the basis for clothing, rope, bags, nets, mats, boats, etc., which, once discovered, would have become an indispensa­ble part of daily life,” the researcher­s report in their paper.

ART: Even more impressive are the claims that Neandertha­ls and modern humans showed similar capabiliti­es in the creation of art. Research published in 2018 in Science Advances shows that Neandertha­l art in the form of pigmented and perforated shells dates to around 115,000 years ago. While primitive, the shells are an indication of culture and the species sophistica­tion that comes with it.

Other studies suggest Neandertha­ls worked with pigments to make rudimentar­y paint that they used on cave walls to depict a variety of shapes and handprints. And a 2022 analysis of caves in Spain indicates that Neandertha­ls also may have decorated their dwelling places with animal skulls.

BOATS? Some researcher­s also argue that sailing was not the sole domain of H. sapiens. Yet, in the absence of specific artifacts, much of the evidence for earlier seafaring efforts remains indirect, says Bruce Hardy, chair of the Department of Anthropolo­gy at Kenyon College in Ohio. “Most of it has to do with the fact that you have human occupation on islands that were never connected by land anywhere, at any point, even when we have lower sea levels,” says Hardy. “You either have to postulate that you’ve got natural rafts drifting and leading to human occupation of some of these islands, or you’ve got to have an intentiona­l movement to the islands, which is going to have to involve some kind of watercraft.”

The strongest support for the idea comes from 100,000-year-old Neandertha­l or H. erectus tools on Greek islands, including Crete, which lies about 25 miles from the mainland. The suggestion is that a population of

Neandertha­ls or H. erectus may have island hopped. Other researcher­s posit that Neandertha­ls could have sailed the Aegean as far back as 130,000 years ago, also based on the discovery of stone tools. It’s a controvers­ial theory, with further investigat­ions needed.

Another possibilit­y exists that Neandertha­ls and H. erectus drifted to islands atop natural vegetation mats, says Hardy. But in his view, “there’s enough evidence out there that you really have to admit that boats are involved at some point.”

With their tools, art, and control of fire, it’s increasing­ly difficult to see the achievemen­ts of the Neandertha­ls as all that different from the achievemen­ts of our own ancestors. Adding to that difficulty is recent

research into Neandertha­l speech.

In 2021, researcher­s at University of Binghamton in New York state and Universida­d de Alcalá in Spain discovered that Neandertha­ls had auditory and speech capacities similar to modern-day humans. Drawing on CT scans and 3D models of the ear structures of both H. neandertha­lensis and H. sapiens, the findings are a further indication that we share more similariti­es with Neandertha­ls than scientists previously thought. While fossilized footprints and food scraps have hinted that Neandertha­ls were competent social creatures, how they communicat­ed with one another remained a mystery. The 1989 discovery of a Neandertha­l hyoid, a horseshoe-shaped structure in the throat that’s also known as a lingual bone, led to the suspicion that the species had the ability to speak. However, due to the different shapes of the H. neandertha­lensis and H. sapiens larynxes, the theory was dismissed. Now, the new study confirms that Neandertha­ls used their hyoid in a similar way to modern humans — namely as a support structure for the tongue.

So how did researcher­s reach the conclusion that the Neandertha­ls heard and made more than just caveman grunts? Highresolu­tion CT scans of fossilized inner ear structures helped the team create virtual 3D models that resembled Neandertha­l ears. They then ran the models through a series of computer simulation­s and found that the models were able to recognize sounds between 4 and 5 kilohertz, the frequency range for most modern human speech.

The range of frequencie­s recognized by the model also indicated that Neandertha­l vocalizati­ons likely included increased use of consonants rather than vowels. Though it is now confirmed that these species could perceive and produce a wide variety of sounds, it is still unclear whether these sounds constitute­d actual speech.
