New Homo naledi evidence supports intentional burial practices

Anthropologist Lee Berger and his team at the University of the Witwatersrand, working within the Rising Star cave system in South Africa, have published their most extensive evidence yet of deliberate burial by Homo naledi, a small brained hominin that walked the Earth with several current modern human cousins over 240,000 years ago.

It began with a Facebook call for short, skinny and fit anthropologists who “must not be claustrophobic.” There is a backstory to the beginning of course, but it is here in this Facebook advert for the smallest in stature and bravest of heart to drop everything and fly to South Africa where the team was assembled.

Their task: delve 30 meters down and explore an over 100 meter-long topography of a treacherous and at times impossibly narrow cave system.

The original announcement of the find in 2015 was met with amazement, some skepticism and a hint of controversy. Amazing because it was impossible to imagine the discovery of a new species of hominin, not by a single bone or fragmented skull, but by a trove of over 1,500 well-preserved fossilized bones from a minimum of 15 individuals, many articulated in place, buried in a cave that had been undisturbed for possibly more than 300,000 years.

With so many fossils awaiting excavation, the team dubbed the most concentrated area within the Dinaledi Chamber the “Puzzle Box.”

Back to Stick Figures: How Woke Warriors Destroyed Anthropology

Biological anthropology and archaeology are facing a censorship crisis. Censorship can be defined simply as the suppression of speech, public communication, or information, often because it is deemed harmful or offensive. It can be enforced by government agencies or private institutions. Even self-censorship is increasingly prevalent, such as when an author decides not to publish something due to fear of backlash from their colleagues, or the belief that their findings may cause harm.

In these fields, censorship is primarily driven by professional associations like the American Anthropological Association (AAA) and the California Society for Archaeology, academic journals (often produced by these associations) such as Bioarchaeology International, universities, and museums, including the Smithsonian National Museum of Natural History. The focus of this censorship largely involves the suppression of images—including X-rays and CT-scans—of human remains and funerary objects, which are artifacts found in graves.

Biological anthropologists, such as bioarchaeologists (who study human remains from the archaeological record), have historically used photos and X-rays of skeletal remains and mummies to explore disease patterns of past peoples, teach new methods of age estimation and sex identification, and attract new students to the field of biological anthropology. Archaeologists use photos of artifacts to facilitate comparisons with other artifacts, aid in reconstructing past cultures, and explore topics like the peopling of the Americas, prehistoric trade patterns, and the emergence of new technologies. These are just a few of the many ways images have been used in the field.

Yet, in recent years, the use of photos of human remains and artifacts has faced increasing censorship. For example, the guidelines of the Society for American Archaeology (SAA) and its journals state: “Out of respect for diverse cultural traditions, photographs of full or explicit human remains are not accepted for publication in any SAA journal.”

Additionally, they add that “line drawings or other renderings of human remains may be an acceptable substitute for photographs.” In other words, they also may not be acceptable! So, the photo on the left would definitely not be accepted in SAA journals, and the image on the right may or may not be accepted.

The Neo-Tribes of Anthropology

Anthropology’s main purpose is to teach us about others—other cultures and people from other times. The study of the other was meant to show us human diversity and similarities. This helps us figure out what stems from culture and what lies in our biology, often with a focus on the shared biology that makes us human.

Anthropology is a wondrous field with research that takes us from the depth of the Amazonian jungle, where Napoleon Chagnon conducted his groundbreaking research on the “fierce people” (the Yanomami), to the Siberian steppes, where anthropologists discovered tattooed ice mummies of the Iron Age buried with their horses. In order to draw conclusions about their discoveries, anthropologists integrate, form bonds with, and converse with those whom they are studying. They also practice archaeology, one of the four subfields of anthropology, which includes, in its data, structures as grand as the Giza pyramids in Egypt and the slender bone needle found in Idaho’s Buhl Burial, which is over 10,000 years old.

Archaeology is the science of what’s been left behind. Physical anthropologists, now often called biological anthropologists, look at fossils such as those of our nearly two-million-year ancestors Homo erectus to reconstruct past lives—the lives of those who couldn’t leave a written record. All of these aspects of traditional anthropology, and the many more I haven’t covered, are fascinating, data-driven, and reveal clearly why anthropology is a true social science.

Anthropologists have provided us with better ways to extract DNA from badly deteriorated human remains. Techniques used in Neanderthal studies are now employed in all sorts of fields, including forensics. Anthropologists have also helped us understand the origins of diseases, for example through their work on the prion diseases (like mad cow and Kuru) tied to cannibalism. Anthropologists have brought us together by figuring out adaptive purposes and other causes of human variation, thereby explaining away discriminatory myths about human differences.

Throughout the U.S., biological anthropology has been a popular choice for students looking to fulfill their science general-education requirement. Cultural anthropology and archaeology often fulfill other general-education requirements, too. Thus, in the U.S., many students of all majors take at least one anthropology class.

Rise of Archery in Andes Mountains Now Dated to 5,000 Years Ago

When did archery arise in the Americas? And what were the effects of this technology on society?

These questions have long been debated among anthropologists and archaeologists. But a study led by a University of California, Davis, anthropologist, published in Quaternary International is shining light on this mystery.

Focusing on the Lake Titicaca Basin in the Andes mountains, anthropologists found through analysis of 1,179 projectile points that the rise of archery technology dates to around 5,000 years ago. Previous research held that archery in the Andes emerged around 3,000 years ago.

The new research indicates that the adoption of bow-and-arrow technology coincided with both the expansion of exchange networks and the growing tendency for people to reside in villages.

“We think our paper is groundbreaking because it gives us a chance to see how society changed throughout the Andes throughout ancient times by presenting a huge number of artifacts from a vast area of South America,” said Luis Flores-Blanco, an anthropology doctoral student and corresponding author of the paper. “This is among the first instances in which Andean archaeologists have investigated social complexity through the quantitative analysis of stone tools.”

Researchers said increasing social complexity in the region is usually investigated through analysis of monumental architecture and ceramics rather than projectile points, which are historically linked to foraging communities.

SCIENTISTS ANALYZING ANCIENT SCYTHIAN ARTIFACTS HAVE MADE A GRUESOME DISCOVERY

Anthropologists studying a collection of ancient Scythian artifacts retrieved during excavations at sites in Ukraine have made a gruesome discovery, according to newly published research.

The multi-institutional team reports that two samples of the ancient Scythian artifacts in question, consisting of small bits of leather, were determined to be made from human skin. The findings, reported in PLOS ONE, confirm ancient accounts of the practices of Scythian warriors, namely those of the Greek historian Herodotus.

Largely a nomadic group who resided in the region now recognized as the Pontic-Caspian steppe between around 700 BCE and 300 BCE, the Scythians remain somewhat mysterious, despite the accounts left to history by Herodotus of their ferociousness in battle.

In The Persian Wars (book IV), the famed “Father of History” presents us with a grizzly account of the behavior of Scythian warriors regarding their fallen enemies.

“Many make themselves cloaks, like the sheepskins of our peasants,” Herodotus wrote, describing how Scythian warriors “make of the skin, which is stripped off with the nails hanging to it, a covering for their quivers.”

“Some even flay the entire body of their enemy, and, stretching it upon a frame, carry it about with them wherever they ride,” Herodotus explains. “Such are the Scythian customs with respect to scalps and skins.”

In their analysis, researchers Luise Ørsted Brandt, Meaghan Mackie, Marina Daragan, Matthew J. Collins, and Margarita Gleba sought evidence for the claims Herodotus made about the Scythians.

Study of Ancient Teeth Shows Single Native American Migration from Asia

The analysis of human teeth recovered during archaeological excavations has remained a standard means of investigating ancient migration patterns for the last five decades. In fact, this tried-and-true methodology has produced some important new results that shed light on the Native American migration from Asia to the Americas at least 16,000 years ago.

According to newly published research appearing in the American Journal of Biological Anthropology, those ancestors left eastern Asia in one gigantic mass movement of people. This Native American migration created a genetic (and dental) unity between different Native American groups that is a reflection of their common roots in that single mass migration.

Dental Anthropology Unlocks Secrets of Native American Migration

Amazingly, dental anthropologists have been able to discover many details about human migration from studying variations in the shapes of human teeth. The teeth in question often originate from individuals who lived in a bygone era, their sole legacy now confined to skeletal remnants left behind to be analyzed by scientists.

But dental anthropologists also study the teeth of modern humans, which helps them determine how teeth have evolved over the course of thousands of years. In the course of their work, these professionals make comparisons between modern and ancient teeth in order to detect ancestral connections between the old teeth and the new (and naturally between the people who possessed those teeth).

For the purposes of this latest analysis, an international team of dental anthropologists from Europe and the United States obtained access to a web-based application/database known as rASUDAS, which allows researchers to identify the ancestry of an unidentified person based on their tooth crown and root traits.

While this forensic application can be used to identify commonalities between the teeth of ancient and modern individuals, and therefore identify ancestry of the modern person, in this case it was used to identify the ancestry of prehistoric people whose teeth had been recovered from archaeological sites in different regions of the world.

Moroccan Cave Find Shows Ancient Humans Made Clothes 120,000 Years Ago

Researchers have announced the discovery of bone tools in a cave in Morocco that appear to have been used to carefully remove skins and fur from the bodies of dead animals. The skins recovered this way were apparently used to make clothing.

Such a find would not normally be considered remarkable. But these particular tools are approximately 120,000 years old, which pushes the timeframe for clothes-making practices farther back into the past than scientists would have once believed was possible. 

“These bone tools have shaping and use marks that indicate they were used for scraping hides to make leather and for scraping pelts to make fur,” anthropologist and research team leader Dr. Emily Hallett explained in a press release from science journal publisher Cell Press.

“At the same time, I found a pattern of cut marks on the carnivore bones from Contrebandiers Cave that suggested that humans were not processing carnivores for meat but were instead skinning them for their fur.”

The ancient fur and leather makers were early Homo Sapiens (modern humans), who at this point had yet to leave Africa to explore and colonize the rest of the planet. Even before the original great migration that scattered their populations across the globe, the earliest humans were showing a surprisingly sophisticated range of behaviors.

“Our study adds another piece to the long list of hallmark human behaviors that begin to appear in the archaeological record of Africa around 100,000 years ago,” stated Dr. Hallett, who along with most of the scientists involved in this research project is affiliated with the Max Planck Institute for the Science of Human History in Germany.

Conference cancels panel on biological sex in human skeletons over transphobia fears: Commits a ‘cardinal sin’

Anthropologists from the largest associations of anthropologists in the world canceled an event discussing the importance of biological sex in the context of studying the human skeleton while citing “transphobia” as the reason for the panel being cut. 

The American Anthropological Association (AAA) and The Canadian Anthropology Society (CASCA) were skewered for walking back their approval for a panel event at its 2023 conference discussing biological sex. The AAA and CASCA said that it was now tightening its review process to ensure such an event wouldn’t recur in the future. 

The event in question discussed “Sex identification whether an individual was male or female – using the skeleton is one of the most fundamental components in bioarchaeology and forensic anthropology.” 

One of the speakers who was slated to attend, Elizabeth Weiss, an anthropology professor at San José State University, said in an interview with FOX News Digital that the field has been nose-diving into an “off the rails” agenda, with activists pushing for some facts to be replaced with feelings. As anthropologists have developed more precise metrics to determine the sex of the human skeleton they study in the field, the more they get attacked for knowing and being able to determine those differences, she said.
