Evolutionary disease-resistance target discovery
PrimaryFauna Bio's central causal theory is that mammals that evolved resistance to extreme stresses or diseases contain genomic and regulatory programs that can reveal therapeutic targets for human age-related disease. By comparing genetic and transcriptomic patterns across hibernating, regenerative, long-lived, or otherwise resilient species and integrating them with human disease genomics, the Convergence platform should identify targets that human-only datasets miss.
Testable predictions are that targets prioritized from conserved or convergent animal resilience traits will map onto human disease pathways, modulating those targets in human cells or models will reproduce protective phenotypes, and these targets will be enriched for effects in diseases such as heart failure, neurodegeneration, fibrosis, metabolic disease, and other age-related decline.

Premise plausibility7.0
The premise is credible: mammals carry conserved and lineage-specific regulatory programs, and extreme traits such as hibernation can point to biology relevant to human disease. The Zoonomia data make the core bet more than hand-waving: 240 placental mammal genomes found 332 million constrained human bases, about 10.7% of the genome, with much of that signal outside coding exons. The weak point is translation. A hibernator surviving metabolic suppression does not prove that the same regulatory program can treat human heart failure, fibrosis, or neurodegeneration. That bridge is plausible, but it still needs perturbation data in human systems.
Supporting evidence: Zoonomia aligned genomes from 240 placental mammals and identified conserved, constrained, and lineage-specific elements associated with exceptional traits such as hibernation.; At least 332 million bases, about 10.7% of the human genome, are unusually conserved across mammals.; Of 101 million significantly constrained single bases, 80% are outside protein-coding exons and half lack ENCODE functional annotations, leaving real regulatory biology outside standard human-centric maps.
Counter evidence: The theory assumes animal resilience traits are mechanistically informative for human age-related disease despite species differences.; The evidence context does not show that Fauna Bio has already converted a cross-species signal into a validated human therapeutic target.; RNA-seq and comparative transcriptomic findings can mislead if study design, sample size, tissue matching, and batch control are weak.
Explanatory power6.0
The theory explains why human-only datasets might miss targets: they usually sample disease variation inside one species, while comparative mammalian genomics can expose regulatory programs selected across deep evolutionary time. That is a real explanatory gain. Still, the current evidence mostly supports the search strategy, not the causal claim that these targets drive protection in human disease. Alternative explanations remain live: conserved elements may reflect basic viability, lineage signals may track unrelated ecology, and transcriptomic convergence may be a response marker rather than a protective mechanism.
Supporting evidence: Comparative genomics can identify mammalian elements linked to exceptional traits, including hibernation.; Large amounts of constrained mammalian sequence are noncoding and incompletely annotated, which gives cross-species analysis a clear reason to find signals missed by standard human annotation.; Perturbation and transcriptomic modeling can infer regulatory mechanisms and cellular responses rather than only observed expression changes.
Counter evidence: The evidence does not yet show that the Convergence platform explains human disease outcomes better than GWAS, human single-cell atlases, perturb-seq, or standard disease biology pipelines.; Conserved or convergent signatures may be correlated with resilient phenotypes without causing protection.; Cross-species mapping across orthologous genes and regulatory elements is an assumption, and regulatory function can shift across species.
Falsifiability8.0
This theory is testable in a clean Popperian sense. It predicts that prioritized animal-resilience targets will map to human disease pathways, that perturbing them in human cells or disease models will reproduce protective phenotypes, and that the target list will show enrichment in age-related disease areas such as heart failure, neurodegeneration, fibrosis, and metabolic disease. Those claims can fail. If prioritized targets do not validate above matched human-only or random baselines, the theory takes a direct hit.
Supporting evidence: The theory names specific validation steps: pathway mapping, target modulation, and protective phenotypes in human cells or disease models.; It predicts disease-area enrichment in heart failure, neurodegeneration, fibrosis, metabolic disease, and other age-related decline processes.; The causal claim can be tested by perturbing prioritized targets and measuring whether protective phenotypes appear.
Counter evidence: Some predictions remain broad unless the platform predefines target-ranking rules, comparator methods, disease models, effect sizes, and success thresholds.; A failed target could be dismissed as a model mismatch unless the theory commits to prospective validation criteria.; Disease-area enrichment is weaker than functional rescue because many genes map loosely onto common disease pathways.

Ashley Zehnder is Fauna Bio's co-founder and CEO, and the public materials attribute this theory directly to her. In the June 10, 2026 Decoding Longevity episode, she is described as explaining how animals that survive extreme biological states can reveal new therapies for heart disease, neurodegeneration, fibrosis, metabolic disorders, and age-related decline. The April 21, 2026 Saving Sapiens episode goes further and states that Fauna Bio layers comparative genomic data from extreme mammals onto human disease genomics to find targets that human-only datasets miss. Her own public post linking hibernation biology to longevity also aligns with the theory rather than merely mentioning it.

Comparative genomics of evolved disease resistance reveals human drug targets
PrimaryFauna Bio's core causal theory is that mammals with extreme natural phenotypes, such as hibernation, regeneration, obesity resistance, metabolic adaptation, muscle preservation, bone preservation, and radiation tolerance, contain evolved genetic and regulatory programs that causally protect tissues from disease-relevant stress. By comparing these species' genomes and disease-resistance states, then integrating the signals with human genomics, the Convergence platform should identify therapeutic targets whose modulation can reproduce protective animal biology in humans.
A testable prediction is that targets prioritized from conserved or convergently evolved mammalian disease-resistance programs will be enriched for causal human disease biology and will modify relevant disease phenotypes in preclinical models, including metabolic disease, muscle wasting, tissue injury, or radiation damage.

Premise plausibility7.0
The starting premise is credible: mammals do carry evolved adaptations to hibernation, tissue protection, metabolism, and stress tolerance, and comparative genomics can find conserved or lineage-specific elements linked to those traits. The strongest anchor is Zoonomia: 240 mammalian genomes, about 332 million constrained bases in the human genome, and trait-linked changes in genes and regulatory elements. The weaker step is translation. A hibernating squirrel's protective program may point to human biology, but it does not prove that a homologous human target can be modulated safely or strongly enough to copy the phenotype.
Supporting evidence: Zoonomia aligned genomes from 240 mammalian species and identified about 332 million evolutionarily constrained human bases, roughly 10.7% of the genome.; The same publication reports that changes in genes and regulatory elements are associated with exceptional mammalian traits such as hibernation.; Veterinary and human medical data can be analyzed together to find translational opportunities across species.
Counter evidence: The core translational assumption remains medium confidence: non-human disease-resistance states may not map cleanly onto human disease mechanisms.; The evidence supplied supports discovery of candidate genomic signals more directly than it supports druggable target modulation in humans.
Regenerative mammals reveal tissue repair programs
Fauna Bio's regeneration theory is that mammals with unusual regenerative capacity, such as spiny mice or tenrecs referenced in company-related materials, carry evolved programs for tissue repair that may be translated into therapies for degeneration, fibrosis, or injury. The causal claim is that comparative genomics can separate conserved mammalian repair mechanisms from species-specific noise and nominate druggable regulators of regeneration.
Testable predictions are that targets derived from regenerative species will enhance repair, reduce fibrosis, or improve functional recovery in human cell, organoid, or animal injury models.

Premise plausibility7.0
The starting premise is credible: some mammals do show unusual repair capacity, and comparative genomics can find conserved and divergent elements linked to exceptional traits. The weaker step is translation. The evidence supports the idea that repair biology can be compared across mammals, but it does not yet prove that the relevant programs are druggable in humans.
Supporting evidence: The theory names concrete source species, including spiny mice and tenrecs, rather than treating regeneration as a generic mammalian property.; The Zoonomia comparative genomics work aligned genomes from 240 mammalian species and found trait-associated changes in genes and regulatory elements.; The evidence context includes RNA-seq power analysis and perturbation modeling as tools that can support rigorous target discovery.
Counter evidence: The key human-translation assumption has no direct supporting publication in the supplied evidence.; Exceptional regeneration may depend on species-specific development, immune response, anatomy, or life-history traits that do not map cleanly onto drug targets.
Explanatory power5.0
The theory explains why regenerative mammals are useful discovery systems, but it only partly explains repair itself. Comparative genomics can nominate candidates; it does not by itself separate causal repair regulators from correlated evolutionary differences. Alternative explanations remain live: unusual regeneration could come from tissue architecture, injury ecology, immune tone, or developmental timing rather than a conserved druggable program.
Hibernation-linked radiation protection
Fauna Bio's RADIANCE theory is that hibernation may induce a physiological state that protects tissues from radiation damage. If hibernation-associated stress-response, metabolic, DNA-repair, or inflammatory programs reduce radiation injury, those mechanisms could be developed for spaceflight health risks and potentially broader age-related tissue damage contexts.
Testable predictions are that hibernation-state signatures or Fauna-prioritized targets will reduce radiation-induced cell death, DNA damage, inflammation, or functional tissue decline in relevant model systems.

Premise plausibility6.0
The premise is biologically credible but still underproven. Hibernation involves coordinated changes in metabolism, stress response, inflammation, and tissue maintenance, and comparative mammalian genomics can identify trait-linked genes and regulatory elements. The weak point is causality: the evidence supplied supports hibernation-linked biology and target discovery, but it does not yet show that those programs directly reduce radiation injury.
Supporting evidence: The theory names plausible mechanisms: stress-response, metabolic, DNA-repair, and inflammatory programs.; Zoonomia aligned genomes from 240 placental mammals and linked genes and regulatory elements to traits such as hibernation.; The evidence context rates the core premise as medium confidence and comparative genomics support as high confidence.
Counter evidence: The causal step is still an assumption: hibernation-associated programs may correlate with hibernation without protecting against radiation.; No supplied publication directly tests radiation exposure in hibernating tissue, hibernation-mimic states, or Fauna-prioritized targets.
Explanatory power4.0
The theory explains a possible route from hibernation biology to radiation protection, but the observed evidence does not yet need that explanation. Comparative genomics can nominate hibernation-linked targets, and perturbation modeling can help predict cellular responses, but those facts also fit weaker explanations: the targets may mark hibernation state, species adaptation, or transcriptional correlation without reducing radiation damage.
Hibernation preserves muscle and bone during disuse
Fauna Bio's space-health and healthspan theory is that hibernating animals resist muscle wasting and bone loss during prolonged inactivity, a phenotype directly relevant to sarcopenia, frailty, and disuse atrophy. The causal claim is that hibernation activates protective programs that suppress catabolism, preserve tissue structure, or enable rapid functional recovery despite long periods of low movement and altered metabolism.
Testable predictions are that hibernation-associated targets will reduce muscle atrophy or bone loss in disuse models, improve recovery after unloading, and overlap with pathways implicated in human frailty, sarcopenia, or spaceflight-associated tissue decline.

Premise plausibility7.0
The premise is biologically credible: hibernating mammals can remain inactive for long periods while avoiding the level of muscle and bone loss expected from ordinary disuse. The leap to human sarcopenia, frailty, and spaceflight decline is plausible but still partly hypothetical. The cited Zoonomia paper supports comparative genomics as a way to find trait-linked genes and regulatory elements, including hibernation-linked biology, but it does not by itself prove that those targets preserve human muscle or bone.
Supporting evidence: The evidence graph states that hibernating animals endure prolonged inactivity and altered metabolism while resisting muscle wasting and bone loss.; The Zoonomia publication reports that genes and regulatory elements can be associated with exceptional mammalian traits such as hibernation.; The theory names concrete tissue outcomes: muscle atrophy, bone loss, and recovery after unloading.
Counter evidence: The main cited publication is broad comparative genomics, not a direct disuse atrophy or bone preservation experiment.; The human translation claim depends on an assumption that hibernation programs overlap with frailty, sarcopenia, and spaceflight-associated tissue decline.
Metabolic flexibility for obesity and neuroprotection
Fauna Bio's metabolic theory is that hibernating mammals undergo extreme, reversible metabolic shifts, including switching fuel use and preserving organ function under low-energy conditions. These natural programs may expose targets that alter obesity-related metabolism or allow neurons and other tissues to tolerate reduced glucose availability by using alternative fuels such as ketones, fatty acids, or lactate.
Testable predictions are that targets discovered from hibernation metabolic signatures will shift cellular or organismal fuel use, improve obesity-relevant metabolic phenotypes, and protect human neuronal models under glucose deprivation or metabolic stress.

Premise plausibility7.0
The starting premise is credible: hibernating mammals do make large, reversible metabolic shifts while preserving organ function under low-energy conditions. The leap to human obesity and neuronal stress biology is plausible, but still partly speculative. The weak point is translation. A hibernation-linked gene or regulatory element can identify a useful biology node, but that does not prove the same node can be safely pushed in human adipose tissue, liver, muscle, or neurons.
Supporting evidence: The evidence context states that hibernating mammals undergo extreme, reversible metabolic shifts while preserving organ function under low-energy conditions.; The Zoonomia publication reports comparative genomic analysis across 240 mammalian species and links genes and regulatory elements to traits such as hibernation.; The theory makes a mechanistic bridge through fuel switching, low-energy tolerance, and alternative substrates such as ketones, fatty acids, or lactate.
Counter evidence: The central translatability assumption is rated only medium confidence in the reasoning graph.; No direct evidence is provided that Fauna Bio targets already shift fuel use in human cells or improve obesity phenotypes.; The neuronal alternative-fuel claim has no supporting publication listed in the supplied evidence.
Hibernation cardioprotection
Fauna Bio's hibernation-based cardiovascular theory is that species such as the 13-lined ground squirrel repeatedly tolerate ischemia-reperfusion-like stress during hibernation without lasting cardiac injury, implying an evolved protective program against tissue damage. If the regulatory networks active in hibernation can be mapped and translated into human biology, they may yield drug targets for heart failure or cardiopulmonary disease.
Testable predictions are that hibernation-derived gene signatures will protect cardiomyocytes or cardiac organoids from ischemia-reperfusion injury, modulating Fauna-prioritized targets will improve functional recovery after hypoxic or reperfusion stress, and the same target networks will overlap with human heart failure biology.

Premise plausibility7.0
The starting premise is credible: hibernating mammals such as the 13-lined ground squirrel do tolerate repeated cycles of low metabolic activity and reperfusion-like stress, and comparative mammalian genomics can flag trait-linked regulatory changes. The weak link is translation. A squirrel hibernation program may protect a squirrel heart inside a whole-body torpor state, with altered temperature, metabolism, autonomic tone, and fuel use. A human heart failure drug has to extract a usable part of that program without requiring the rest of the animal state. That is plausible, but still a large biological jump.
Supporting evidence: The evidence graph states that hibernating mammals repeatedly tolerate ischemia-reperfusion-like physiological stress without lasting cardiac injury.; Zoonomia aligned genomes from 240 placental mammals and linked changes in genes and regulatory elements to exceptional mammalian traits, including hibernation.; The theory names testable human-relevant systems: cardiomyocytes, cardiac organoids, hypoxic stress, reperfusion stress, and heart failure biology.
Counter evidence: The translation assumption is low-confidence in the evidence graph: protective mechanisms may be species-specific adaptations.; The cited support includes broad comparative genomics and perturbation-method papers, but no direct Fauna target, cardiac rescue assay, or human heart failure validation result.; Hibernation physiology is whole-organism biology, so cardiac protection may depend on systemic conditions that a drug cannot reproduce cleanly.
Hibernation-associated radiation protection
Project RADIANCE is described as studying the protective effects of hibernation against radiation. The causal theory is that hibernation biology produces a physiological state that limits radiation-induced damage, potentially through stress-resistance mechanisms that could be relevant to spaceflight and, by extension, tissue protection under genotoxic stress.
A testable prediction is that hibernation-associated molecular or metabolic states will reduce radiation-induced cellular damage, tissue dysfunction, or delayed degenerative effects compared with non-hibernating controls.

Premise plausibility6.0
The premise is biologically credible, but still thin. Hibernation is a real mammalian state with unusual metabolic and regulatory features, and the supplied evidence links hibernation-related traits to comparative genomics. The jump from hibernation biology to radiation protection is plausible because radiation injury can involve oxidative stress, DNA damage response, inflammation, and delayed tissue dysfunction. We do not yet have direct evidence here that a hibernation-associated state reduces radiation damage.
Supporting evidence: Project RADIANCE is described as testing whether hibernation protects against radiation-induced biological damage.; The Zoonomia publication reports that changes in genes and regulatory elements are associated with exceptional mammalian traits such as hibernation.; The theory makes a coherent causal claim: hibernation-associated molecular or metabolic states could reduce damage after genotoxic stress.
Counter evidence: The evidence context does not include direct radiation experiments in hibernating animals, induced hibernation-like states, tissues, or cells.; The mechanism is broad: stress resistance could mean DNA repair, antioxidant control, metabolic slowing, immune regulation, or several other processes.
Natural obesity resistance reveals anti-obesity targets
Fauna Bio's obesity collaboration with Eli Lilly is based on the theory that animal models with natural disease resistance or extreme metabolic adaptations contain causal genetic programs that can be mined for obesity drug targets. The Convergence platform is expected to connect mammalian comparative biology with human genomics to find targets that regulate weight, adiposity, or metabolic health.
A testable prediction is that targets identified through this cross-species resilience approach will alter obesity-relevant endpoints, such as fat accumulation, energy utilization, insulin sensitivity, or body-weight gain, in preclinical obesity models.

Premise plausibility7.0
The premise is biologically credible: mammals do show extreme metabolic adaptations, and comparative genomics can identify conserved or lineage-associated elements tied to exceptional traits. The weak link is causal translation. A genomic signal that helps a hibernator, desert mammal, or disease-resistant species survive its niche may not regulate human obesity in a druggable way.
Supporting evidence: The Zoonomia resource aligned genomes from 240 placental mammal species and identified 332 million constrained bases, about 10.7% of the human genome.; The evidence context states that changes in genes and regulatory elements are associated with exceptional mammalian traits such as hibernation.; The theory includes a plausible bridge from comparative mammalian biology to human genomics, rather than relying on animal traits alone.
Counter evidence: The provided evidence does not show Fauna Bio target validation in obesity models.; The assumption that non-human resilience programs are conserved enough to matter in human obesity is marked only medium confidence.; The platform's ability to separate causal obesity programs from correlated evolutionary signals is explicitly low confidence.
Hibernation-like metabolism preserves muscle and systemic health
Fauna Bio's space and hibernation programs imply that metabolic shifts used during torpor can protect animals from muscle loss, metabolic dysfunction, and other deterioration that would normally accompany inactivity or extreme stress. The proposed mechanism is not a single pathway in the supplied material, but a coordinated hibernation state involving altered fuel use and tissue-protective gene regulation.
A testable prediction is that inducing selected hibernation-associated metabolic programs in human cells, organoids, or animal models will preserve muscle mass or improve metabolic resilience during inactivity, obesity, or other stress states.

Premise plausibility6.0
The starting premise is credible: hibernating mammals do tolerate prolonged inactivity and physiological stress in ways that ordinary non-hibernating animals usually do not. The weak point is translation. The supplied material supports hibernation as a rich biological model, but it does not show that a selected subset of hibernation programs can be induced cleanly in human systems or that those programs will preserve muscle and systemic health without tradeoffs.
Supporting evidence: The evidence context states that hibernation and torpor are coordinated metabolic states linked to tolerance of prolonged inactivity or extreme physiological stress.; The Zoonomia comparative genomics paper reports genetic and regulatory changes associated with exceptional mammalian traits, including hibernation.
Counter evidence: The mechanism is broad: altered fuel use plus tissue-protective gene regulation, without a named causal pathway.; The assumption that hibernation-associated programs can be selectively induced in human cells, organoids, or non-hibernating animal models is marked low confidence.
Hibernation protects against ischemia-reperfusion injury
Fauna Bio appears to use hibernating mammals, especially ground squirrels, as models for natural tolerance to repeated ischemia-reperfusion-like stress. The causal claim is that hibernation induces coordinated molecular programs that preserve cardiac and other tissue function despite repeated metabolic suppression and rewarming cycles, and that reproducing parts of those programs could treat human heart failure or other age-related injury states.
A testable prediction is that genes or pathways active in hibernation cycles will reduce cell death, inflammation, fibrosis, or functional decline in human cardiac models exposed to ischemia-reperfusion stress.

The premise is credible: hibernating mammals do survive repeated cycles of metabolic suppression and rewarming, and comparative genomics can flag genes and regulatory elements linked to traits such as hibernation. The weak point is the disease model bridge. Hibernation resembles ischemia-reperfusion stress in some metabolic features, but the evidence here does not prove that the same injury mechanisms dominate in human heart failure.
Supporting evidence: The theory starts from a concrete biological phenotype: hibernating mammals tolerate repeated suppression and rewarming cycles.; The Zoonomia publication reports that genomic changes can be associated with exceptional mammalian traits, including hibernation.; The theory names a plausible causal layer: coordinated molecular programs, rather than a single vague protective factor.
Counter evidence: The similarity between hibernation cycles and human ischemia-reperfusion injury is still an assumption in the provided evidence.; No direct human cardiac perturbation data are provided showing that hibernation-linked pathways protect tissue under ischemia-reperfusion stress.
Hibernation-associated stress responses protect against radiation injury
Project RADIANCE is based on the theory that hibernation produces a physiological state that protects tissues from radiation exposure, potentially through coordinated DNA damage response, metabolic suppression, inflammation control, oxidative-stress resistance, or tissue-preservation mechanisms. Identifying and reproducing these hibernation-associated protective pathways could reduce radiation injury in humans exposed to space radiation or other radiation stressors.
A testable prediction is that hibernation-linked targets or gene programs will reduce radiation-induced cellular damage, tissue injury, functional decline, or mortality in experimental models compared with non-modulated controls.

The premise is biologically credible but still under-specified. Hibernation changes metabolism, inflammation, oxidative stress handling, and tissue maintenance, so radiation protection is a reasonable hypothesis. The weak point is causality: the supplied evidence supports comparative discovery of hibernation-linked genes and regulatory elements, but it does not show that those programs protect irradiated tissue when moved outside natural hibernation.
Supporting evidence: The theory names plausible mechanisms: DNA damage response, metabolic suppression, inflammation control, oxidative-stress resistance, and tissue preservation.; The Zoonomia publication reports that changes in genes and regulatory elements are associated with exceptional mammalian traits such as hibernation, which may inform therapeutic development.; The reasoning graph explicitly predicts reduced cellular damage, tissue injury, functional decline, or mortality after modulation of hibernation-linked targets.
Counter evidence: No supplied publication directly shows that hibernation protects tissues from radiation exposure.; The theory assumes that hibernation-associated pathways can be reproduced outside natural hibernation.; The theory also assumes that hibernation-linked targets are causal protectors rather than correlated markers of the hibernation state.
Hibernation-like programs preserve muscle and bone during disuse
Fauna Bio's space-focused programs imply a causal theory that hibernating mammals resist the usual consequences of prolonged immobility, including muscle loss and bone loss, by activating protective physiological and molecular programs. Replicating those programs in humans could reduce disuse-related wasting during spaceflight and potentially in terrestrial age-related or disease-related frailty contexts.
A testable prediction is that genes or pathways induced during hibernation will preserve muscle mass, muscle function, bone density, or tissue repair capacity under unloading, immobility, or other catabolic stress models.

The starting premise is credible: hibernating mammals can remain immobile for long periods without the level of muscle and bone loss expected from ordinary disuse. The mechanistic step is weaker. Zoonomia supports the idea that comparative mammalian genomics can point to genetic and regulatory changes linked to traits like hibernation, but it does not show that any specific hibernation-induced pathway can preserve human muscle or bone under unloading.
Supporting evidence: The evidence graph states with medium confidence that hibernating mammals resist some usual consequences of prolonged immobility, including muscle loss and bone loss.; Zoonomia aligned genomes from 240 mammalian species and reported genetic and regulatory changes associated with exceptional traits such as hibernation.; The theory has no internal contradiction: a protective disuse program in hibernators could, in principle, be tested in unloading or catabolic stress models.
Counter evidence: The transfer-to-human assumption is low confidence in the provided evidence.; The evidence does not identify a named gene, pathway, dose, tissue, or intervention that already preserves human muscle or bone.; Natural hibernation bundles reduced metabolism, temperature shifts, endocrine changes, feeding state, and seasonal physiology, so the causal component may not be a single portable program.
Hibernation biology can protect against metabolic and obesity-related disease
Fauna Bio's obesity collaboration appears to rest on the theory that hibernating or metabolically extreme mammals undergo large, reversible shifts in energy balance, fat storage, insulin sensitivity, and fuel use without developing the same chronic pathology seen in human obesity and metabolic disease. If the molecular switches enabling these adaptive metabolic states are identified, drugging analogous pathways in humans could improve obesity or related metabolic dysfunction.
A testable prediction is that Convergence-prioritized obesity targets will alter body weight, adiposity, energy expenditure, appetite, glucose handling, or lipid metabolism in preclinical models, and that these effects will map back to protective metabolic programs observed in extreme mammalian models.

The stronger claim, that humans can be drugged into selected parts of that program without harmful tradeoffs, is still a hypothesis. The evidence supports target discovery more clearly than therapeutic safety.
Supporting evidence: Zoonomia aligned genomes from 240 mammalian species and linked conserved or changed genomic elements to exceptional traits, including hibernation.; The theory rests on a real biological observation: some mammals tolerate seasonal fat gain and metabolic switching without the chronic disease pattern seen in human obesity.
