Presentation of the intuition/hypothesis
The following is an excerpt from a major research project on interaction with AI (Grok3) in July 2025, following intuitions, questions, and inquiries from my neurodivergent brain about the origin of the dog (Canis Familiaris) and what a Dog is.
History is (re)written by the victors and never corresponds to reality. The dog is Canis familiaris, and familiaris means familiar, but also servant and servile, and therefore dependent on humans. And it is humans who tell the story of how they domesticated and enslaved the wolf into a dog, in an anthropocentric, anthropoegocentric, anthropoegoistic vision.
My neurodivergent and arborescent thoughts often cause me to unconsciously reverse the words in the sentence: “Humans domesticated wolves into dogs” becomes “What if it were wolves who tamed humans?”
Who took the first step towards the other?

The She-Wolf Who Changed Humankind (PopSci)
36,000 years ago, in the frozen steppes of Goyet, Belgium, a wolf rewrote history. Forget the conquering human domesticating the wolf. It was she, moved by empathy, who offered the first gift.
Under a starry sky, the wolf, in pseudocyesis, felt oxytocin flood her body. Her maternal instincts drove her to protect, as she would her cubs. She spotted a young human girl, starving, prowling near a deer carcass. Humans, clumsy omnivores from the lush Sahara, break bones to survive. Th
ey pose no threat to her pack, invincible apex predators.
In a bold gesture, the wolf brings, or even regurgitates, a piece of meat for the girl. A gift. The humans, amazed, stop brandishing their spears. Soon, they hunt together: the pack drives the game, the human spears strike. This pact, born of a wolf's empathy, gives birth to the dog.
Science confirms it: tolerant wolves carrying docile genes (WBSCR17, OXTR) became proto-dogs in Goyet. Humans adapted, their genes (AMY2B, OXTR) promoting cooperation. Myths, from Romulus and Remus to Shoshone legends, sing the praises of this nurturing she-wolf.
This “anthropo-lykie” turns history on its head: the wolf “lycanized” humans, teaching them collaborative hunting. Under the stars of Goyet, she extended her paw. And we took it.
What if the dog was a wolf's dream?

I, the She-Wolf of Goyet, gave a gift (Poetic PopSci)
I am the wolf of Goyet, 36,000 winters ago. Under the icy stars, my pack hunts deer, our fangs stronger than human spears. They, the two-legged ones, are weak, breaking bones to survive. They do not frighten us. We wolves rule the steppe.
My body is changing. Without cubs, a warmth fills me, as if I were carrying life. My instincts cry out: protect, nurture. I see a young two-leg, thin, trembling near our carcass. She is not a threat, but a lost cub. I regurgitate a piece of deer, a gift. She looks at me, her eyes shining. No fear, no hunt. A bond is born.
My pack tolerates the two-legged ones. They follow in our tracks, their spears killing what we drive down. Together, we thrive. My gentler descendants will stay close to their fires, becoming “dogs.” The two-legged creatures will also change, learning our hunting techniques, their minds sharpening like our fangs...
The elders still sing my story: Romulus fed by my Roman sister, or the Shoshone hunter guided by my brother. We wolves have reached out our paws. Out of empathy, we have “lycanized” the two-legged ones, offering them our strength. But I wonder: have they understood our gift?
And you, do you hear the call of the wolf?

Abstract
The domestication of the dog (Canis lupus familiaris) between -41,500 and -20,000 years represents a cornerstone of human evolution, traditionally viewed through an anthropocentric lens as a process driven by human (anthropogenic) selection and care. This article proposes a wolf-centric hypothesis, positing that wolves, as 'apex collaborative social predators' endowed with altruistic behaviors and hormonal mechanisms such as pseudocyesis, initiated a cooperative pact with Homo sapiens in the glacial steppes of Eurasia.
Drawing on genetic, ethological, archaeological, and mythological evidence, we integrate contributions from three key researchers: Juliet Clutton-Brock's cultural-archaeological framework on human-driven integration; Bryan Sykes's genetic narrative on mutual "pacts" via
mitochondrial DNA and behavioral mimicry; and Pat Shipman's ecological model on human-dog alliances as invasive superpredators contributing to Neanderthal extinction.
This synthesis supports an "anthropo-lykie" – a bidirectional transformation where wolves "lupinize" humans through empathetic provisioning, enhancing complementary skills: wolves' mastery of pack hunting and humans' tool innovation.
Amid abundant megafauna during the Aurignacian (30,000–50,000 years), this pact genetically remodeled both species, fostering social cognition and ecological dominance.
By challenging anthropocentric biases, we reframe (bidirectional or reciprocal) domestication as an interspecies dialogue, with profound implications for contemporary ethology and conservation. This reformulation invites an interspecies ethics: honoring wolf agency to repair the wounds of our shared history.


Introduction
The origins of dog domestication remain one of evolutionary biology's most enduring enigmas, marking the first instance of deep interspecies symbiosis and catalyzing Homo sapiens' global dispersal (Bergström et al., 2022). Conventional narratives, rooted in archaeological and genetic data, date this event to 41,500–20,000 years in Eurasia, during the transition from the Middle to Upper Paleolithic (Perri et al., 2021). Yet, these accounts often privilege human agency (agency, capacity for action): wolves (Canis lupus), attracted by camp waste, undergo unconscious selection for docility, yielding today's loyal dog-companion (Freedman et al., 2019).
This anthropocentric paradigm, though empirically grounded, occludes the intrinsic agency of wolves as intelligent, altruistic predators capable of interspecies empathy.
Inspired by ethnographic myths – such as the she-wolf Lupa nursing Romulus and Remus (Ovid, Fasti) or Asena saving a Turkish boy-warrior (Dumézil, 1970) – and ethological observations of wolf altruistic and maternal (parental) behaviors, this hypothesis proposes a creation of the partnership, initiated and driven by the wolf.
In resource-rich glacial steppes, pseudocyetic she-wolves, hormonally prepared for care, may have extended "gifts" of regurgitated meat or tolerance (near carcasses) to vulnerable humans, forging a pact that genetically and behaviorally transformed both parties.
We name this bidirectional coevolution the "anthropo-lykie," evoking the lupinization of human sociality as much as the humanization of wolves.
To test and refine this model, we integrate three seminal perspectives:
  • Juliet Clutton-Brock (Domesticated Animals from Early Times, 2012) emphasizes cultural integration, where the human care instinct incorporates wolves into social structures, attested by Natufian burials (~12,000 years). Her work provides a base for human selection but minimizes wolf initiative.
  • Bryan Sykes (The Wolf Within, 2018): Through mitochondrial DNA phylogenies and narrative vignettes (e.g., the she-wolf Lupa's "conversation of death"), Sykes envisions a mutual pact emerging from observational mimicry during persistence hunts, with genetic divergence ~40,000 years.
  • Pat Shipman (The Invaders, 2015; Our Oldest Companions, 2021) frames the alliance as an ecological "invasion," where proto-dogs amplify human hunting efficiency, contributing to Neanderthal extinction via trophic cascades. Shipman highlights co-domestication – dogs "domesticate" human emotions via oxytocin-linked gaze-following – closely aligned with our empathetic mechanism.
These complementary perspectives converge toward our lupocentrism: the human is not the tamer, but the partner transformed by the wolf's "gift".
This article proceeds with ecological-behavioral foundations, archaeological-genetic evidence, cultural memory, and a discussion integrating contrasts, leading to implications for evolutionary theory.

Ecological and Behavioral Foundations
The Aurignacian period (50,000–30,000 years) in Eurasia provided an ecological crucible for interspecies alliance: vast steppes teeming with megafauna – mammoths, woolly rhinoceroses, giant deer – sustaining overlapping predator guilds without acute scarcity (Perri et al., 2021).
Homo sapiens (with dark skin), migrating from Africa's lush savannas, faced adaptive challenges: their omnivorous diets, rich in C3 plants and fish, clashed with the vitamin D3-poor glacial regime, forcing reliance on bone marrow scavenging and opportunistic (carnivorous) necrophagy (Richards & Trinkaus, 2009).

In contrast, wolves thrived as collaborative apex hunters, their pack dynamics enabling endurance pursuits surpassing human spear-throws, limited to ~20 meters effective range.
Shipman's invasion biology lens (The Invaders, ch. 7) illuminates this: Humans entered as "flexible omnivores," disrupting guilds via fire and atlatls, but wolves' tolerance – rooted in pack confidence – prevented outright conflict. Unlike h
yenas' territoriality, wolves, when resources are plentiful, shared kills, as observed in modern analogs (e.g., Yellowstone wolf reintroductions restoring trophic balance; Sykes, ch. 10).
Clutton-Brock (2012, p. 45) complements this culturally: Early humans' "care instinct," honed on infants, extended to orphaned wolf pups, fostering initial bonds. Yet, her model implies unidirectional human agency, overlooking wolves' proactive altruism.
Central to our wolf-driven hypothesis are (1) pseudocyesis in female wolves, and (2) altruism-empathy-compassion within the wolf family-pack:
(1) Pseudocyesis in female wolves, a post-ovulatory hormonal cascade: progesterone withdrawal elevates prolactin and oxytocin, inducing lactation, nest-building, and cross-species adoption (Root Kustritz, 2006). In ~20-30% of cycles, this state persists 2-3 months, priming females to "mother" proxies – vulnerable humans (children, elders, pregnant women) perceived as pseudo-pups via olfactory/gestural cues (Dwyer & Foltin, 2016). Ethnographic parallels abound: Modern wolves regurgitate for foxes or adopt fawns (Morell, 2013).

(2) Current observations of today's wolves, direct descendants of the common ancestor and cousins of current familiar dogs, feral dogs, village dogs…, show that wolves care for the less-valid pack members, such as pregnant or nursing females, young, sick, wounded… to whom the hunters bring back food, while they hide or are protected by some talented guardians.... This intrinsic pack altruism – evident in regurgitation, grooming, and sentinel duties – extends beyond kin, as seen in cross-species fostering (e.g., wolves aiding injured coyotes; Packard, 2003).
These two mechanisms - hormonal and social - form the heart of the lupine pact, linking the body of the wolf to the spirit of the pack.

In the glacial context, such behaviors likely bridged to sapiens: A pseudocyetic she-wolf, denned near a camp, regurgitates for "pseudo-pups," eliciting human reciprocity – scraps for protection – mirroring Sykes's Lupa vignette (ch. 1), where shared carcasses spark "mutual recognition."
Behaviorally, this aligns with Hare's "survival of the friendliest" (2017): Wolves' baseline sociability (gaze-following superior to solitary predators) selected for empathetic variants, amplified by oxytocin surges during interspecies contact (visual and tactile) (Shipman, Companions, ch. 3: WBSCR17 SNPs fostering hyper-gregariousness). Clutton-Brock's care (2012, p. 67) fits as a human response, but our model inverts: Wolf initiative via pseudocyesis and pack compassion creates the asymmetry, with humans as "opportunistic scavenging beneficiaries”.
Ecologically, megafaunal plenty (Shipman: no "overkill" pressure pre-alliance) delayed competition, allowing this pact 40,000 years – post-Neanderthal overlap (45,000 years; Shipman, Invaders, ch. 3) – when sapiens' cognitive revolution (Chauvet art; Sykes, ch. 7) enabled symbolic reciprocity.
This foundation challenges fear-based models (ancestral human dread of wolves): Packs, numerically superior, viewed sapiens as non-threats, per modern observations (Ellis immersion; Sykes, ch. 9).
Thus, behavioral convergence – pack altruism mirroring tribal cooperation – paved the way for genetic entanglement.

Archaeological and Fossil Evidence
Archaeological records anchor the pact's timeline, revealing proto-dogs at sapiens sites absent from Neanderthal ones, suggesting selective alliance. Shipman's The Invaders (ch. 12) spotlights Goyet Cave (Belgium, ~36,000 years ago): Canid skulls with crowded dentition and shortened snouts – morphological harbingers of domestication – co-occurring with Aurignacian tools (blades, bone needles). Similarly, Předmostí (Czech Republic, ~27,000 years ago) yields 40+ wolf-like remains with isotopic signatures of mammoth-provisioned diets, implying human feeding (Germonpré et al., 2012; Shipman, Companions, ch. 1). These "incipient dogs" (Olsen criteria: reduced carnassials) predate agriculture, aligning with our ~40,000-year divergence.
Clutton-Brock (2012, ch. 2) contextualizes culturally: Natufian burials (~12,000 years ago, Israel) inter humans with puppies, signaling emotional bonds and property norms. Extending backward, she posits Eurasian camps as "domus" (Latin for home) where wolves entered via scavenging, selected for tameness. Yet, her Euro-Middle Eastern focus (p. 89) contrasts Shipman's polycentric model (European/Asian hearths; Companions, ch. 6), and both overlook wolf agency – e.g., no Neanderthal canids despite shared niches (Shipman, Invaders, ch. 9: metabolic rigidity doomed them).

Fossil microwear corroborates our pseudocyesis trigger: Goyet canids show dental erosion from soft foods (and acid regurgitation?), suggesting maternal provisioning (Drake et al., 2015).
Chronologically, Bergström et al. (2022) refine divergence to 41,500–20,000 years via ancient DNA, with clades A-D (Sykes, ch. 3: mtDNA trees) clustering Eurasian wolves. Sykes favors Europe over East Asia (Savolainen hypothesis), citing American dog lineages tracing to Beringian migrants (~15,000 years; Perri et al., 2021).
Chronological Constraints
MIS 3 volatility (60,000–25,000 years ago) compressed sapiens-Neanderthal overlap to ~5,000 years (Shipman, Invaders, ch. 3: Iberian redatings ~41,000 years). Post-extinction, alliance timing fits: Bonn-Oberkassel burial (14,500 cal. BP) pairs human and dog in red ochre, evoking ritual kinship (Clutton-Brock, 2012, p. 102). No earlier evidence (e.g., Denisova Cave ~50,000 years) supports our glacial abundance window – pre-agricultural sedentism unnecessary.
These chronological constraints are intertwined with more concrete ecological signatures...
Ecological Signatures
Cut-mark densities on megafauna (Swabian Jura; Shipman, ch. 11) indicate coordinated hunts: Wolf herding into human ambushes.
Clutton-Brock's "property" (2012, p. 56) emerges later; initially, it's symbiotic tolerance.

Genetic and Coevolutionary Dynamics
Genomics unveils the pact's molecular imprint: Bidirectional selection yielding "dogginess" in wolves and "wolfiness" in humans.
Sykes's mtDNA odyssey (The Wolf Within, ch. 3–5) clocks divergence ~76,000–135,000 years, but ancient sequencing narrows to ~40,000 (Thalmann et al., 2013; Bergström et al., 2022). Four clades dominate, with Y-chromosome skews revealing few sires – hallmark of human-influenced breeding. Neutral mutations (one/20,000 years) date bottlenecks; our model posits pseudocyesis as accelerator: Empathetic females transmit OXTR variants (oxytocin receptor), enhancing cross-species bonds (Freedman et al., 2019).

Shipman's co-domestication (Companions, ch. 13; Invaders, ch. 14) echoes: Dogs neotenize (floppy ears via Belyaev foxes; Sykes, ch. 21), while "domesticate" humans via gaze-following (white scleras ~30,000 years; Hare, 2017).
WBSCR17 SNPs, similar to Williams syndrome's hyper-sociability, foster loyalty – bidirectional, as human FOXP2 (speech/language) and AMY2B (starch digestion) evolve ~40,000 years, adapting to wolf-provisioned meat and camp carbs (Lazaridis et al., 2017).
Wolf-to-Human Gene Flow
Reverse introgression: Dog melanism alleles flow to wild wolves (Sykes, ch. 19), mirroring human Neanderthal admixture (~2%; Shipman, Invaders, ch. 2). Reverse introgression, observed in modern wolves (up to 25% canine DNA in some populations; Sykes, ch. 19), suggests a persistent permeability of genetic barriers.
Our anthropo-lykie extends: Oxytocin surges during pseudocyesis "gifts" select for human prosociality, per Hare (2017). Clutton-Brock (2012, p. 78) notes behavioral paedomorphosis (retained juvenile traits), but attributes it to human selection; we argue wolf empathy precedes, with fossils (Goyet AMY2B copies) confirming early starch tolerance.
Coevolutionary Feedback Loops
Shipman's superpredator duo (human tracking + wolf olfaction) collapses guilds, felling megafauna (ch. 7). Sykes's "dance of life" (ch. 18: meiosis shuffling) models rapid adaptation; integrated, pseudocyesis initiates accelerating loops: Tolerant wolves provision, humans reciprocate, selecting the docility of wolves-who-become-dogs.
Thus, anthropo-lykia is not a straight line, but a virtuous circle in which each species sculpts the other.
Genetic clocks align: Post-40,000 years, dog genomes show 1.5M SNPs for sociability (Broad Institute; Sykes, ch. 16). Human side: Eurasian OXTR variants enhance empathy, "lupinizing" tribal coordination (Hare, 2017). Clutton-Brock's cultural evolution (2012, ch. 3: property norms) sustains, but our model reveals wolf primacy.


Mythological and Cultural Memory
Myths encode the pact's "deep structure" (Lévi-Strauss, 1963): Wolves as initiators of aid. These stories are not mere fables, but cultural fractals, repeating the 'lupine gift' across continents and millennia. As analyzed by Lévi-Strauss (1963), these myths structure the collective unconscious, encoding forgotten evolutionary truths.

Shoshone legends describe wolves guiding hunters to elk (Lowie, 1924); Yakut epics feature white wolves sharing prey (Eliade, 1972). The Roman Lupa (Ovid) and Turkish Asena (Dumézil, 1970) evoke pseudocyetic nurturing – cross-species lactation (breastfeeding) as cultural archetype.
Sykes (ch. 10–11) contrasts: Inuit shamans as wolf-kin preserve symbiosis, countering Euro-folklore's "Big Bad Wolf." Clutton-Brock (2012, p. 120) traces Anubis cults (~3000 BCE) to prehistoric reverence; Shipman (Companions, ch. 16) links to American migrations (Anzick burial).
Our hypothesis: These are "memories" of ~40,000-year gifts, amplified by oral traditions.

Discussion: Integrating Multidisciplinary Perspectives
Synthesizing our quadrangulation:
Clutton-Brock's nurturing (human-led integration) provides cultural scaffolding but marginalizes wolf agency, assuming scavenging as passive lure (2012, p. 45).
Sykes's pact (mutual mimicry; ch. 1) bridges, with Lupa's shared kills echoing our pseudocyesis "gifts," yet retains sapiens' observational primacy.
Shipman's ecology (invasive cascades; Invaders, ch. 7) and co-domestication (Companions, ch. 13: emotional reciprocity) align closest, positing wolves as active allies in Neanderthal displacement – our model specifies pseudocyesis as trigger, explaining selective sapiens sites.
Critically, anthropocentric biases persist: Clutton-Brock's "domus" (p. 23) implies human enclosure; Sykes's genetics (mtDNA) risks Euro-bias (ch. 6); Shipman's invasivity indicts sapiens without wolf heroism.



Our anthropo-lykie proposes solutions: Wolves initiate when there's an abundance (of resources), humans (disabled? inferior? certainly in need of assistance) respond - bidirectional, via OXTR feedback.
Limitations: Fossil gaps (no direct pseudocyesis evidence); future aDNA from maternal lines could test.
Ethically, we rephrase: honoring the lupine agency in interspecies collaboration and proposing a pact that placed the wolf-sapiens dyad as predatory apex (Sykes, ch. 15).
To test, agent-based simulations (inspired by Hare, 2017) could m
odel pseudocyesis vs. scavenging-only scenarios.


Conclusion / Ethics
Dog domestication emerges not as human triumph, but as a wolf-driven pact – triggered by empathy and pseudocyesis, sealed in glacial steppes. Integrating Clutton-Brock's culture, Sykes's genes, and Shipman's ecology, the anthropo-lykie reveals the interspecies dialogue that shaped us.
The wolf extended a paw; our sapiens ancestor grasped it 40,000 years ago. Together, they invaded the Earth, destroying all competing guilds and megafauna in their path.
Then, I don't know when, sapiens-the-deceiver betrayed the pact: instead of sharing kills equitably, he gave the scraps to the wolves, then proceeded to the genocide of the Wolf (his master/sensei), keeping only wolf-dog-servants (servile) becoming Dogs, dependent on the Human or, if still listening to Asena's howl, returning to the wild, creating new branches of
canid cousins (feral Cani, Dingo, Pariah, …).
Today, reintroducing the wolf (e.g., Yellowstone) is not remediation, but restitution of the original pact. Today the Wolf, in Europe, reconquers stolen territories, approaches houses, and takes 'the wolf's share' in poorly protected livestock.
Future research: model pseudocyesis via agent-based simulations; map the 'betrayals' of the pact and the beginning of the Wolf's genocide (e.g., agricultural transition ~10,000 years).
Final call: Interdisciplinary studies (ethology + ancient DNA genetics) will validate this lupinization, inviting ethical reintroductions (e.g., Yellowstone wolves as 'restitutio pacti').
