The narrative of North America’s earliest inhabitants has undergone a significant revision, thanks to an extraordinary discovery in the arid landscape of Oregon. Fossilized human feces, scientifically known as coprolites, unearthed from a cave system, have yielded compelling evidence pushing back the timeline of human presence on the continent by over a millennium. This groundbreaking find, meticulously analyzed by a team of researchers, suggests that humans thrived in North America as early as 14,340 years ago, challenging the long-held belief that the Clovis culture represented the continent’s first settlers. This article delves into the details of this remarkable discovery, its implications for our understanding of early human migration, and the insights it provides into the lives of these ancient North Americans.

Unearthing the Past: The Paisley Caves Discovery
The key to rewriting North American prehistory lies within the Paisley Caves, a series of eight caves located in the south-central Oregon desert. These caves, formed by wave action during the Pleistocene epoch, have long been of interest to archaeologists due to their potential to preserve organic materials over extended periods. In this arid environment, the dry conditions proved ideal for the preservation of coprolites, offering a unique window into the diet and DNA of early humans.
The discovery of these ancient feces was not accidental. Dr. Dennis L. Jenkins, an archaeologist at the University of Oregon, led a team that meticulously excavated the caves, carefully sifting through layers of sediment. It was during this painstaking process that the fossilized feces were discovered, their significance initially recognized by their unusual composition and location within the cave strata.
DNA: A Genetic Link to Siberia and East Asia
What makes these coprolites particularly remarkable is the presence of human DNA. The DNA extracted from the fossilized feces revealed a genetic signature closely related to populations in Siberia and East Asia. This finding strongly supports the widely accepted theory that the first inhabitants of North America migrated from Asia across the Bering Land Bridge, a now-submerged landmass that once connected Alaska and Siberia during periods of lower sea levels.
The genetic evidence provides crucial information about the origins of these early North Americans. It suggests that they were part of a larger migration wave that spread across the globe, eventually reaching the Americas. This discovery strengthens the connection between the ancient populations of North America and their Asian ancestors, providing a clearer picture of the complex human story of migration and adaptation.
A Glimpse into the Diet of Ancient Americans
Beyond DNA analysis, the coprolites offer a unique opportunity to reconstruct the diet of these early inhabitants. Microscopic examination of the fossilized feces revealed a diverse range of food sources, including bones of small mammals such as squirrels, bison hair, fish scales, bird protein, and even traces of canid (dog) remains. Plant remains, such as grass and sunflower seeds, were also identified, indicating a varied and adaptable diet.
This dietary information paints a vivid picture of the resourcefulness of these early North Americans. They were skilled hunters, capable of capturing a variety of animals, and they also utilized plant resources to supplement their diet. The presence of dog remains raises intriguing questions about the relationship between humans and canids at this early stage. Were dogs used for hunting, companionship, or even as a food source? Further research is needed to fully understand this complex relationship.
Challenging the Clovis Paradigm: A Pre-Clovis Presence
The most significant implication of this discovery is its challenge to the long-held belief that the Clovis culture represented the earliest human presence in North America. The Clovis culture, characterized by its distinctive fluted spear points, has been dated to between 13,200 and 12,900 years ago. For decades, the Clovis people were considered the ancestors of most Native American populations, and their arrival marked the beginning of human history in North America.
However, the Paisley Caves coprolites, dated to 14,340 years ago, provide irrefutable evidence of a human presence that predates the Clovis culture by more than a thousand years. This discovery fundamentally alters our understanding of the peopling of the Americas, suggesting that there were earlier migrations and populations that existed alongside or even before the Clovis people.
The Significance of 14,340 Years Ago
The dating of the oldest coprolite to 14,340 calendar years ago is crucial. This date was determined through radiocarbon dating, a reliable method for determining the age of organic materials. The consistency of the dates obtained from multiple coprolites further strengthens the validity of the findings. The meticulous dating process ensures that the evidence is robust and can withstand scientific scrutiny.
The 14,340-year-old date places these early North Americans within a critical period in Earth’s history. The last glacial maximum, a period of extreme cold and widespread glaciation, was coming to an end, and the climate was beginning to warm. This period of environmental change likely played a significant role in the migration patterns and adaptations of early human populations.
Implications and Future Research
The discovery of the Paisley Caves coprolites has far-reaching implications for the study of early human migration and adaptation. It opens up new avenues of research and challenges existing assumptions about the peopling of the Americas. Future research will focus on further analyzing the DNA from the coprolites to gain a more detailed understanding of the genetic relationships between these early North Americans and other populations around the world.
Archaeologists will also continue to excavate the Paisley Caves and other sites in North and South America to search for additional evidence of pre-Clovis human presence. The discovery of more artifacts, such as stone tools and other human remains, will provide further insights into the lives and cultures of these early inhabitants. The Poop fossil proves human habitation in North America 14,340 years ago find has invigorated the field of archaeology and promises to reveal even more about the fascinating story of human migration and adaptation in the Americas.
The Broader Context: Monte Verde and Other Pre-Clovis Sites
The Paisley Caves discovery is not an isolated finding. Evidence of pre-Clovis human presence has been found at other sites in the Americas, most notably at Monte Verde in southern Chile. Monte Verde, dated to around 14,500 years ago, has yielded a wealth of artifacts, including stone tools, plant remains, and even the remains of dwellings. These findings provide further support for the existence of pre-Clovis populations and suggest that the Americas were populated earlier and more diversely than previously thought.
The discovery of Poop fossil proves human habitation in North America 14,340 years ago and the pre-Clovis site of Monte Verde underscores the need for a reevaluation of the traditional Clovis-first model. The story of the peopling of the Americas is far more complex and nuanced than previously imagined, with multiple waves of migration and diverse populations contributing to the rich tapestry of Native American cultures. The evidence continues to mount, solidifying the presence of humans in North America well before the Clovis era, as Poop fossil proves human habitation in North America 14,340 years ago.
