Beth Shapiro’s work in ancient DNA and her move to Colossal
Joe welcomes Beth Shapiro back and frames Colossal’s work—especially the dire wolves—as groundbreaking and controversial. Beth introduces paleogenomics (ancient DNA), why it rewrites history, and why she left academia to become Colossal’s Chief Science Officer.
Academia’s scarcity mindset, gatekeeping, and why public communication matters
They discuss how academic incentives can foster negativity, territorial behavior, and resistance to outsiders or new approaches. Joe argues podcasts bypass traditional gatekeepers; Beth notes colleagues may resent her speaking on a platform like JRE.
From broadcast journalism to field science: the pivot that changed her life
Beth recounts starting in broadcast journalism (TV/radio) before realizing science offered the stories she wanted to tell. A nine-week field geology/archeology road program across North America hooked her on deep time, landscapes, and human impact.
How she got into ancient DNA: clean labs, contamination, and ‘go to Siberia’
Beth explains how meeting Alan Cooper in the late 1990s introduced her to the specialized clean-room labs needed for ancient DNA work. The core challenge is preventing modern contamination from overwhelming degraded fragments—plus the irresistible lure of fieldwork in Siberia.
Siberia and Arctic fieldwork stories: mosquitoes, boats, and survival logistics
Beth and Joe swap vivid stories about Siberia and Alaska field conditions, especially the extreme mosquito swarms and unpredictable infrastructure. Beth describes expeditions searching for mammoth material and how quickly conditions can become miserable or dangerous.
Taymyr expedition madness: helicopters, medical ethanol, and armed visitors
Beth recounts an especially chaotic Taymyr Peninsula expedition: malfunctioning helicopters, camping in a poorly chosen glaciated site, and coping with limited supplies. The story escalates when armed men appear at 2 a.m., later revealed to be local Dolgan reindeer herders investigating the helicopter sighting.
Subsistence cultures, happiness, and what modern life does to our bodies
Joe references Herzog’s ‘Happy People’ to explore why harsh subsistence lifestyles can still be fulfilling. Beth connects modern mismatch to obesity/diabetes, and they broaden into learning from uncontacted or traditional societies without destroying them.
Uncontacted tribes, Amazon archaeology, and disease-driven collapses
Joe describes stories from Amazon conservation work and the danger of contact, including lethal encounters and human rights abuses. They connect this to new evidence (LiDAR) showing large ancient Amazon civilizations and how disease and reforestation may erase traces.
Jurassic Park questions and the real origins of ancient DNA science
Beth explains that ancient DNA wasn’t born from Jurassic Park—Jurassic Park drew inspiration from real early work. She tells the famous contamination story where ‘dinosaur DNA’ matched chicken, likely due to fried-chicken handling, illustrating how the field learned rigor the hard way.
PCR, DNA decay, and how clean labs made Neanderthal/Denisovan genomes possible
They dig into the technical backbone of ancient DNA: PCR, fragment degradation, microbial mixtures, and strict contamination controls. Beth highlights the achievement of assembling Neanderthal genomes and the discovery of Denisovans from a tiny finger bone.
New human species finds, island dwarfism, and nature’s brutality (Komodo detour)
They riff on recent paleoanthropology headlines (large-skulled ‘Jularrenesis’), Flores ‘hobbits,’ and why hot climates destroy DNA. The conversation detours into Komodo dragons—feeding behavior, venom debates, and a notorious zoo attack story—before returning to evolutionary oddities like island dwarfism.
Dire wolves up close: awe, ethics, and the ‘are we playing God?’ reaction
Joe describes visiting Colossal’s dire wolves and the visceral sense they are ‘different’ from familiar wolves. Beth shares being present at Khaleesi’s birth and frames de-extinction as a rare source of public awe—while Joe voices ethical and ecological unease about reintroducing extinct predators.
From de-extinction to conservation: genetic rescue, red wolves, and fixing human-caused problems
Beth argues Colossal’s core value is building tools for biodiversity preservation, not just spectacle. She explains genetic rescue with the Florida panther example and outlines the red wolf project—using wild hybrid lineages and genome tools to restore lost diversity.
Invasive-species ‘solutions’ gone wrong: honey badgers, snails, and the hippo plan
They explore the recurring human mistake of introducing species to control other species, from Hawaii’s rosy wolf snail disaster to Florida’s python problem. Beth tells the wild 1910 ‘American hippo ranching’ proposal—importing hippos to eat invasive water plants and become meat—plus parallels like Colombia’s Escobar hippos and US feral pigs.
Species concepts, hybrids everywhere, and how DNA reshapes definitions (including ‘beefalo’ fraud)
Beth reframes the ‘not a real dire wolf’ critique as a misunderstanding of species concepts and how nature ignores our categories. They discuss hybridization (polar/brown bears; humans/Neanderthals), why names are tools not truths, and Beth shares her team’s recent genomic work showing many ‘beefalo’ are essentially just cattle.
