Recent research challenges the traditional view of early human diets in the Andes, suggesting a shift from “hunter-gatherers” to “gatherer-hunters.” The study, analyzing remains from the Wilamaya Patjxa and Soro Mik’aya Patjxa sites in Peru, reveals an 80 percent plant-based and 20 percent meat diet among early Andeans. This finding, based on isotope chemistry and statistical modeling, contradicts previous beliefs and influences current perceptions of diets such as the Paleodiet. It also indicates a need to reassess archaeological frameworks globally.

The commonly used term “hunter-gatherers” for describing early humans should be revised to “gatherer-hunters” in the context of the Andes in South America, suggests groundbreaking new research led by an archaeologist from the University of Wyoming.
Archaeologists long thought that early human diets were meat-based. However, Assistant Professor Randy Haas’ analysis of the remains of 24 individuals from the Wilamaya Patjxa and Soro Mik’aya Patjxa burial sites in Peru shows that early human diets in the Andes Mountains were composed of 80 percent plant matter and 20 percent meat.
The study was recently published in the peer-reviewed journal PLOS ONE. It applies methods in isotope chemistry and statistical modeling to unveil a surprising twist in early Andean societies and traditional hunter-gatherer narratives.
“Conventional wisdom holds that early human economies focused on hunting — an idea that has led to a number of high-protein dietary fads such as the Paleodiet,” Haas says. “Our analysis shows that the diets were composed of 80 percent plant matter and 20 percent meat.”
Evidence of Plant-Dominant Diets
For these early humans of the Andes, spanning from 9,000 to 6,500 years ago, there is indeed evidence that hunting of large mammals provided some of their diets. But the new analysis of the isotopic composition of the human bones shows that plant foods made up the majority of individual diets, with meat playing a secondary role.

Additionally, burnt plant remains from the sites and distinct dental-wear patterns on the individuals’ upper incisors indicate that tubers — or plants that grow underground, such as potatoes — likely were the most prominent subsistence resource.
Multidisciplinary Research and Student Involvement
“Our combination of isotope chemistry, paleoethnobotanical, and zooarchaeological methods offers the clearest and most accurate picture of early Andean diets to date,” Haas says. “These findings update our understanding of earliest forager economies and the pathway to agricultural economies in the Andean highlands.”
Joining Haas in the study were researchers from Penn State University, the University of California-Merced, the University of California-Davis, Binghamton University, the University of Arizona, and the National Register of Peruvian Archaeologists.
Undergraduate students also had the opportunity to conduct research during the initial 2018 excavations at the Wilamaya Patjxa burial site.
Currently a Ph.D. student in anthropology at Penn State University, Jennifer Chen, the journal article’s lead author and a former undergraduate student in Haas’ research lab, performed the isotope lab work and much of the isotope analysis following the excavations.
“Food is incredibly important and crucial for survival, especially in high-altitude environments like the Andes,” Chen says. “A lot of archaeological frameworks on hunter-gatherers, or foragers, center on hunting and meat-heavy diets — but we are finding that early hunter-gatherers in the Andes were mostly eating plant foods like wild tubers.”
Haas notes that archaeologists now have the tools to understand early human diets, and their results are not what they anticipated. This case study demonstrates for the first time that early human economies, in at least one part of the world, were plant-based.
“Given that archaeological biases have long misled archaeologists — myself included — in the Andes, it is likely that future isotopic research in other parts of the world will similarly show that archaeologists have also gotten it wrong elsewhere,” he says.
Haas investigates human behavior in forager societies of the past to better understand human behavior in the present. He leads archaeological excavations and survey projects in the Andes and mountain regions of western North America.

Vegan Cave Man Ping!...................
Given the state of Science! and peer reviews I am going to dismiss this out of hand as another piece of sponsored Science! to support the narrative.
More about what the funding entity wants than any actual science.
We are deep into a new dark age where science is a tool of the elite and the scientific method has been raped.
there wuz no buffalos downn there in Peru but there was upn the Great Plains...these ghuys are morons.
...another surprising finding from the research: early humans also spend most of their time in their parent’s basement in their pajama’s...
And, by the way, EAT THE BUGS!
This is what happens when you allow vegans to become paleontologists. I wonder what all those spears and arrow heads were for.
It does not. Just a courtesy reading of the study shows that it does not say that but like "Black English were more likely to die of the Black Death because of Systemic Racism" they will lie and lie and lie and trust that you don't read the rest of what they say.
Not even reading this. Don’t believe it. Gates and Soris probabky paid for the study.
Because plants are easier to catch than animals.
“Rewriting History”
As we continue on the path to outlaw meat, particularly beef, we can expect more and more of these articles. And, like ‘Climate Change’, there will be no room for deniers.
(who would have guessed that we would wind up being the Soviet Union, after winning the Cold War)
They are basing this stupid study on a single population IN THE ANDES!! WHAT KIND OF LARGE ANIMALS LIVE IN THE ANDES?? The indigenous population there raised GUINEA PIGS for protein!! Stupid study!!!
‘vegetarian’......old Indian word for ‘Piss Poor Hunter’............
After a lifetime of eating grass they invented the SPEAR, spear thrower, and bow and arrow. Meat is good!
Genesis says man was to eat nothing but plants until Noah left the ark, then God said both plants and animals were ok to eat.
The body only cares about getting the nutrition. It doesn’t care about the source. It certainly would have been less work to grow a plant than to traverse hundreds of miles to capture a deer.
The only disadvantage of eating plants is that they are light in calories, so you will have to eat a lot more often to obtain the necessary calories.
“Not even reading this. Don’t believe it. Gates and Soros probably paid for the study”
$$$$$$$$$$$$$$$$$$$
Oh, believe it. But also believe that their average life span was about 27 years”.
Yeah, if you reclassify gorillas and early humans...
