Four years ago, while volunteering at the University of Montana Zoological Museum, we received an intriguing call from Montana Fish, Wildlife and Parks. A gray wolf had been hit by a car, and we were tasked with preparing it as a research specimen. This process, which included skinning and gutting, was filmed to demonstrate how museums transform road-killed animals into valuable research materials. Along the way, we encountered a humorous mishap involving a misdialed phone call, adding a light-hearted moment to our educational series. These videos allowed us to explore anatomy and physiology, but they only scratched the surface of the deeper questions surrounding wolves and their complex relationship with humans.
Wolves are among the most studied animals globally, with a rich and ancient relationship with humans. In the United States, we recognize gray wolves, eastern wolves, and red wolves as distinct types, alongside Mexican wolves, Arctic wolves, and Great Plains wolves as subspecies or populations of these three. The history of human-wolf conflict is long and complex, often described as “the longest and most relentless persecution one species has waged against another.” To many, wolves symbolize wilderness and environmental integrity, while to others, particularly ranchers, they represent a threat to livestock and livelihoods.
Before European settlers arrived, the land now known as the United States was home to diverse Native peoples and abundant wildlife, including an estimated 380,000 wolves. However, with the arrival of the Pilgrims in the early 1600s, efforts to eradicate wolves began, driven by fears rooted in Old World myths and the need to protect livestock. As settlers depleted the natural prey of wolves, such as bison and deer, conflicts intensified, leading to nearly four centuries of hunting, trapping, and poisoning.
By the mid-1960s, gray wolves were nearly extinct in the U.S. It wasn’t until the Endangered Species Act of 1973 that they received protection. Dr. Larry Heaney from The Field Museum noted that in the early 1970s, only about 200 wolves remained in the Great Lakes area. As wolves were eradicated, coyotes filled the ecological void, adapting to new habitats and avoiding persecution.
Following the Endangered Species Act, gray wolf populations began to recover, with individuals dispersing from southern Canada and Minnesota. Wolves employ a strategy called directional dispersal, moving away from their birth pack to establish new territories, sometimes traveling as far as 550 miles.
As new wolf packs spread, red and eastern wolves encountered coyotes, leading to hybridization. Recent research shows significant coyote DNA in these wolves, raising questions about their classification and conservation status. Genetic studies using museum specimens have provided insights into the evolutionary history of North American canids, with The Field Museum housing one of the largest collections of wolf skeletons.
In 2012, the U.S. Fish and Wildlife Service recognized the eastern wolf as a distinct species. However, a recent study found that red and eastern wolves are hybrids, complicating their conservation status. The Endangered Species Act lacks provisions for hybrids, posing challenges for their protection.
Despite these challenges, conservation efforts continue, including successful captive breeding programs for the Mexican wolf in Arizona and New Mexico. As of 2015, there were an estimated 5,500 wolves in the lower 48 states, far fewer than before their eradication. The complexities of hybridization and legal protections present significant challenges, but science aims to provide information to guide societal decisions on adapting laws to reflect the realities of nature.

Engage in a seminar where you will discuss the historical and current conservation efforts for wolves. Prepare a short presentation on a specific aspect of wolf conservation, such as the impact of the Endangered Species Act or the role of captive breeding programs. Collaborate with your peers to explore the challenges and successes of these efforts.
Participate in a role-playing debate where you will represent different stakeholders in the human-wolf conflict, such as ranchers, conservationists, and government officials. Develop arguments based on historical and contemporary perspectives, and engage in a structured debate to understand the complexities of this relationship.
Join a field trip to a nearby wildlife reserve or national park where wolves are present or have been reintroduced. Observe their natural habitat and behavior, and discuss with wildlife experts the ongoing conservation efforts and challenges faced in maintaining wolf populations.
Participate in a workshop focused on the genetic analysis of wolves and their hybridization with coyotes. Learn about the techniques used in genetic research and how these findings impact conservation strategies. Analyze genetic data to understand the evolutionary history and classification challenges of North American canids.
Attend a screening of a documentary about wolves, such as “The Rise of Wolves” or “Wolves: A Legend Returns to Yellowstone.” After the screening, engage in a guided discussion about the themes presented, including the ecological role of wolves, their cultural significance, and the future of their conservation.

So, four years ago, as a volunteer at the University of Montana Zoological Museum, we received a call from Montana Fish, Wildlife and Parks about a gray wolf that had been hit by a car. We filmed aspects of the preparation process, including skinning and gutting it. This was to show how museums turn road-killed animals into valuable research specimens. That series also included a humorous incident where I accidentally misdialed a local business, which became one of the funniest moments in the history of The Brain Scoop. Those videos allowed us to discuss anatomy and physiology, but we didn’t delve into the questions that the specimen could help us answer, nor did we explore the complex history of wolves and humans or the important role wolves play as top predators in their ecosystems.
Wolves are among the most studied animals on our planet, and their relationship with humans is ancient. There is a vast amount of information available, making it challenging to know where to start. For this video, we will recognize gray wolves, eastern wolves, and red wolves as distinct types in the U.S., along with Mexican wolves, Arctic wolves, and Great Plains wolves as populations or subspecies of those three.
The conflict between wolves and humans has been described as “the longest and most relentless persecution one species has waged against another.” In the book “Wolves,” the authors note that to many humans, wolves symbolize wilderness and environmental integrity, while to others, such as ranchers, they represent a threat to livestock and rural livelihoods.
The animals discussed in this episode are part of a larger, intricate narrative about American human and scientific history, ethics, endangered species, and the challenges of fitting the complexities of nature into legal frameworks.
Before European settlers arrived in what is now the United States, this land was home to diverse Native peoples and abundant wildlife, including wolves, with an estimated population of around 380,000 individuals. However, as soon as the Pilgrims arrived in the early 1600s, they began efforts to eradicate wolves, having previously exterminated them in England and Europe.
Human-wolf conflict is an ancient story. Depending on cultural perspectives, wolves have been viewed as symbols of strength or as creatures to be eliminated. The settlers’ fears, influenced by Old World myths, and the need to protect livestock justified their removal. As settlers depleted the natural prey of wolves, such as bison and deer, conflicts increased.
The hunting, trapping, and poisoning of wolves continued for nearly four hundred years, leading to the near extinction of gray wolves in the U.S. by the mid-1960s. It was not until the creation of the Endangered Species Act in 1973 that gray wolves received protection, being listed a year later.
Dr. Larry Heaney, a curator of mammals at The Field Museum, noted that in the early 1970s, there were only about 200 wolves in the Great Lakes area due to extensive eradication efforts. As wolves were eliminated, coyotes began to fill the void left by their absence, adapting to new habitats and avoiding persecution.
After the Endangered Species Act, gray wolf populations began to rise, with individuals dispersing from southern Canada and Minnesota. Wolves practice a strategy called directional dispersal, moving away from their birth pack to establish their own territory. Some wolves have been recorded traveling as far as 550 miles from their birthplace.
As these new packs spread, red wolves and eastern wolves encountered coyotes instead of other wolves, leading to hybridization. Recent research indicates that red and eastern wolves have significant coyote DNA, raising questions about their classification and conservation status.
Genetic studies using museum specimens provide valuable insights into the evolutionary history of North American canids. The Field Museum houses one of the largest collections of wolf skeletons, which have contributed to recent studies on the transformations of native dogs in North America.
In 2012, the U.S. Fish and Wildlife Service published a monograph detailing the different kinds of wolves in the U.S., confirming the eastern wolf as a distinct species. However, a recent study found that red and eastern wolves are hybrids, complicating their conservation status.
The Endangered Species Act does not have provisions for hybrids, leading to challenges in protecting these animals. The legal framework for protection is rigidly based on clear taxonomic lines, which can hinder conservation efforts.
Despite these challenges, conservation efforts continue, including captive breeding programs for the Mexican wolf, which have seen success in reestablishing populations in Arizona and New Mexico.
Today, there are still far fewer wolves in the U.S. than before their eradication, with an estimated 5,500 in the lower 48 states as of 2015. Conservation efforts are ongoing, but the complexities of hybridization and legal protections present significant challenges.
Science aims to provide information about these issues, and society must decide how to adapt laws to reflect the realities of nature.
