The Why Files: Operation Podcast
Hosted by AJ Gentile
Written by a model from the transcript; not yet reviewed.
Historian Dan Flores discusses his 40-year career writing the biographies of North American wild animals, focusing on the remarkable resilience of coyotes and the historical war waged against predators by the federal government. He and the host explore the deep history of the American West, examining Pleistocene footprints at White Sands, the truth behind early American exploration and the Red River expedition, and the recent de-extinction work of Colossal Biosciences. Flores explains how coyotes outsmarted decades of eradication campaigns through a social adaptation called fish infusion, expanding their range across the continent while other species vanished.
The show opens with a brief AI-focused advertisement before introducing the episode’s guest.
Host announces Dan Flores, a historian who has written extensively on North American wildlife.
Dan explains why coyotes survived the Pleistocene extinction and became a central figure in Native American lore.
Dan recounts his first publication in Sports Afield and the impact it had on his career.
Dan describes a memorable 13‑year‑old experience spotting a fox and its influence on his interest in animals.
Dan explains how the Bureau of Biological Survey transitioned from scientific study to aggressive predator extermination.
Dan details how coyotes hybridize with eastern and red wolves, forming coy‑wolves, and the implications for conservation.
The conversation turns to the Murray brothers’ role in early 20th‑century predator eradication efforts.
The hosts discuss the use of strychnine poison baits and the cruelty involved in killing wolves and coyotes.
Dan recounts the massive scale of predator killings in the early 1900s and the long‑term effects on wildlife populations.
The discussion turns to the widespread use of poison baits to kill wolves and coyotes, highlighting the unintended deaths of many other species.
Ecologists like Aldo Leopold and Joseph Grinnell began to argue against mass extermination, insisting that predators should be preserved in national parks.
The Muri brothers conduct field studies in Yellowstone and the Grand Tetons, concluding that coyotes are largely beneficial and not a threat to wildlife.
Despite massive funding and millions of coyotes killed, the poison campaigns failed to eliminate the species, which continued to spread across the continent.
Coyotes’ individualistic behavior, rapid reproduction, and ability to avoid poison allow them to thrive and colonize new areas, including the eastern U.S. and the Darien Gap.
Coyotes are moving southward, crossing the Panama Canal, and may soon reach the Colombian side of the Darien Gap, potentially becoming the first mammals to bridge North and South America in millions of years.
The conversation shifts to 23,000‑year‑old footprints showing early humans interacting with megafauna, suggesting coastal migration rather than a land bridge.
Debate over whether human hunting, climate change, or disease caused the extinction of large Pleistocene animals, with emphasis on the lack of clear evidence for a global impact.
Discussion of why large mammals like horses and camels vanished in North America while surviving elsewhere, touching on pathogen introduction and genetic isolation.
The discussion opens with the evolutionary adaptations of pronghorns and their survival through Pleistocene predators.
Narration of Thomas Jefferson’s lesser-known southern expedition, its planning, and its ultimate failure.
The conversation turns to the historical status of bison and bald eagles as national symbols and conservation efforts.
First Magazine Salestory
The guest recounts selling his first piece about crows and ravens to Sports Afield as a college junior, receiving a $300 check and an instruction to buy a camera.
Decoding Human Foiblesinsight
The guest explains that Native American coyote stories use trickster plots to mirror human flaws like gluttony, narcissism, and vanity.
Mange as Weapondata
The guest details how the state of Montana passed an act in 1905 requiring state veterinarians to infect captured wolves and coyotes with sarcoptic mange.
Fish Infusion Adaptationstrategy
The guest explains how coyotes survive high-intensity culling by dispersing into singles and pairs, unlike wolves that stay in vulnerable packs.
The guest describes a 23,000-year-old footprint site at White Sands showing a teenager carrying a toddler, interacting with a rearing ground sloth.
Jeffersonian Southern Expeditionstory
The guest explains Thomas Jefferson's forgotten Red River expedition, which was twice as expensive as Lewis and Clark but turned back by Spanish troops.
De-Extinction via CRISPRstrategy
The guest explains how Colossal Biosciences used DNA extracted from 73,000-year-old dire wolf skulls and CRISPR to engineer modern genetic replicas.
“For most of the last century, the federal government tried to erase one animal from the continent with poison, bounties, and money from Congress.”
“A teenage girl, a toddler on her hip, a ground sloth rearing up when it catches her scent.”
“Take me back to your, you're a junior in college, you're meeting with your creative writing professor and something ends up in Sports Afield.”
“But the original check for that piece was $300.”
“The reason the coyote was picked is because it was seen as a survivor, and it was a survivor that lived by its wits.”
“The Wolves of North America. And it's basically a celebration of how we have wiped wolves off the face of the continent.”
“The only thing you can kind of argue is that, and you know, there's a very famous argument in about 2005, that maybe this is a possibility, that as humans arrive, they're bringing new pathogens with them that are infecting some of these animal populations.”
“10,000 years ago, when they were being pursued, really by fast hunting hyenas, and by American cheetahs.”
“Everyone's got a hard question about AI. Your job, your kids, where it's going.”
“Well, bison is the correct scientific name. But of course, I think what you're referring to is the fact that we think most of the animals that we manage to preserve do carry cattle genes.”
