Jamestown colonists brought donkeys, not just horses, to North America, old bones reveal

2025-10-07
(Press-News.org) A new study published in Science Advances about centuries-old horse and donkey bones, unearthed in Jamestown, Virginia, is rewriting the story of how these animals first arrived in North America.

While written records from the earliest English explorers show that horses were among the animals brought to Virginia, the new zooarchaeological analysis of animal remains found at Jamestown is the first to show that colonists also brought donkeys to the New World.

The study also reveals a dark ending to these equids in the colony: The horses and donkeys were likely butchered and eaten during Jamestown’s infamous winter of starvation.

“There are no written records of donkeys on ship manifests and reports, yet evidence suggests they were valued as dependable work animals,” said John Krigbaum, Ph.D., professor and chair anthropology at the University of Florida. Krigbaum served as the senior author on this study alongside lead author William Taylor, Ph.D., at the University of Colorado Boulder.

The team’s work is a testament to the vast amount of information researchers can glean from just a small collection of centuries-old animal bones. With their preliminary tests, archaeologists linked the earliest parts of the settlement to the "Starving Time" winter of 1609-1610, a connection later confirmed by radiocarbon dating. The study provides an early glimpse into how and why horses and donkeys were transported and managed and how they were able to spread and establish wild populations across the continent.

Assisting Krigbaum with both the research and writing were George Kamenov, Ph.D., a senior associate in the Department of Geological Sciences, UF doctoral student Diana Quintero-Bisono and Nicolas Delsol, a former postdoctoral student at the Florida Museum of Natural History who currently works at Université Laval in Quebec.

With the species and timeframe confirmed, further tests unveiled new insights into how these animals once lived. Wear and tear on the bones showed evidence of bridling, suggesting their use as work animals. Ancient DNA and bone chemistry analysis of the isotopes in tooth enamel suggested that the donkey did not originate in Great Britain but was picked up by settlers along the route of their transatlantic journey.

“Ancient DNA points to Iberia or West Africa, which is consistent with its isotope signature, but the isotopic evidence is also consistent with Trinidad and Tobago, which is not far off the route sailed,” said Krigbaum. 

Examining the wear and tear on the samples also revealed a tragic end for many of these animals. Faced with hunger during the Starving Time and having soured their relationships with nearby indigenous people, settlers were forced to eat their animals and, in the direst situations, their dead. While we have records that horses were consumed during this time, this can also be observed with other samples, including donkey remains. “They show that adult horses were eaten, butchered and cooked or boiled, with most elements split open to extract even the minutest nutritional resources including dental pulp,” the team wrote in their study.

For Krigbaum and his colleagues, the Jamestown assemblage is just the beginning. Their next project will examine horse remains from the 16th century Spanish settlement of Puerto Real, in the Caribbean, to uncover further evidence of how horses and donkeys helped shape the earliest chapters of American history.

FIU cybersecurity researchers develop midflight defense against drone hijacking

2025-10-07
MIAMI (Oct. 7, 2025) – As drones become increasingly common in U.S. skies – delivering packages, inspecting bridges, even monitoring crops – the danger of cyberattacks has grown too. A drone hijacked by hackers could suddenly veer off course, speed up, stall in midair, or crash. Once compromised, the machine is useless, often left as little more than expensive junk. Florida International University researchers have found a way to fight back. At the IEEE International Conference on Dependable Systems and Networks, FIU computer scientists unveiled SHIELD, a defensive system that can detect and neutralize ...

Kennesaw State researcher aims to discover how ideas spread in the digital age

2025-10-07
From viral videos to debates over new products, ideas move faster than ever in today’s digital age. Mehmet Aktas, an associate professor of data science and analytics, is leading National Science Foundation-funded research that looks into how those ideas spread, evolve, and shape communities. Funded through a collaborative NSF grant, Aktas is working with colleagues from Georgia State University and Georgia Gwinnett College to explore new ways of modeling information diffusion. Aktas’s project studies how information flows within networks of people. Traditional approaches treat communication like a chain of one-to-one interactions, ...

Next-generation perovskite solar cells are closer to commercial use

2025-10-07
As renewable energy technologies advance, researchers aim to make solar power more efficient, affordable, and durable. Scientists from Kaunas University of Technology (KTU), Lithuania, in collaboration with international partners, have achieved one of the highest efficiencies ever reported for fully inorganic perovskite solar cells. They have also demonstrated for the first time that these cells can operate stably for hundreds of hours, approaching the reliability of commercial silicon solar cells. “Perovskite solar cells are one of the fastest-growing solar technologies in the world – they can be lightweight, thin-film, and flexible, and most importantly, they are ...

Sleep patterns linked to variation in health, cognition, lifestyle, and brain organization

2025-10-07
Researchers led by Aurore Perrault at Concordia University, Canada and Valeria Kebets at McGill University, Canada, have used a complex data-driven analysis to uncover relationships among multiple aspects of sleep and individual variation in health, cognition, and lifestyle. Published on October 7th in the open-access journal PLOS Biology, the study reveals five sleep-biopsychosocial profiles and their associated patterns of functional connectivity among brain-regions. Most studies of sleep focus on a single aspect, such as duration, and examine how it relates to a ...

The world’s snow leopards are very similar genetically. That doesn’t bode well for their future

2025-10-07
There are relatively few snow leopards in the world, and it has likely been that way for a long time, a new study indicates. This situation increases their risk of extinction in a changing environment. The Stanford-led research, published in Proceedings of the National Academy of Sciences, found very low genetic diversity among the elusive big cats, who have an estimated population of less than 8,000. They are also highly specialized to their habitat in the arid, mountainous regions of 12 Asian countries, including Russia, Afghanistan, Nepal, and Tibet. “Snow ...

Researchers find key to stopping deadly infection

2025-10-07
Rotavirus causes severe dehydrating diarrhea in infants and young children, contributing to more than 128,500 deaths per year globally despite widespread vaccination efforts. Although rotavirus is more prevalent in developing countries, declining vaccination uptake in the United States has resulted in increasing cases in recent years. New research from Washington University School of Medicine in St. Louis has identified a key step that enables rotavirus to infect cells. The researchers found that disabling the process in tissue culture ...

Leafcutter ants have blind spots, just like truck drivers

2025-10-07
We have all been in that situation: the moving boxes are large and heavy, but we are determined to carry them all in one trip, even if that means we can’t see where we’re going. In the tropics, some leaf-cutter ants face a similar challenge: carrying a load that is several times their body weight. To make matters even more difficult, scientists at the Smithsonian Tropical Research Institute (STRI) in Panama recently discovered that carrying oversized weights may create “blind spots” when leafcutter ants transport ...
