Evolutionary Competition as Religion
A Biological Perspective on Maori and Vaisnava Sahajiya Traditions
Exploring how religious traditions function as evolutionary adaptations through comparative case studies
The Unexpected Evolutionary Advantage of Faith
What if religion isn't just a matter of faith, but an evolutionary tool that helped certain human groups survive and prosper?
Imagine two seemingly unrelated traditions—the Maori of New Zealand and the Vaisnava Sahajiya of medieval India—both developing religious practices that gave them a competitive edge in the struggle for existence. This isn't about proving or disproving spiritual truths, but about understanding how religious behaviors might have functioned as survival strategies in human evolution. Recent research at the intersection of biology, anthropology, and religious studies suggests that certain religious traditions may have provided tangible advantages that enhanced their followers' evolutionary success 1 4 .
Group Cohesion
Religious practices strengthen social bonds and enhance cooperation within groups
Biological Fitness
Some religious practices may directly enhance reproductive success and survival
The Evolutionary Lens: Understanding Religion Through Biology
Adaptation or Accident? Science's Great Debate
Evolutionary scientists approach religion with a fundamental question: Why would a behavior that often involves significant costs—economic sacrifices, celibacy, dangerous rituals, or substantial time investment—persist and spread unless it provided some compensatory advantages? 1 This puzzle has led to several competing theories about religion's origins and persistence.
Adaptationist
Religion evolved because it conferred evolutionary advantages
By-product
Religious beliefs emerged accidentally from cognitive mechanisms
Cultural Meme
Religious ideas propagate like viruses regardless of biological benefit
Evolutionary Explanations for Religious Behavior
| Theory | Core Mechanism | Key Evidence | Primary Advocates |
|---|---|---|---|
| Adaptationist | Religion enhances group cooperation and survival | Longevity of religious communes; health benefits | David Sloan Wilson, Richard Sosis |
| By-product | Religious belief as accidental output of cognitive mechanisms | Hyperactive Agency Detection Device (HADD); Theory of Mind | Pascal Boyer, Justin Barrett |
| Cultural Meme | Ideas that spread like viruses regardless of biological benefit | Self-replicating nature of religious concepts | Richard Dawkins |
The Maori Worldview: Religion as Group Evolutionary Strategy
The Maori people of New Zealand developed a sophisticated religious worldview that served as a powerful mechanism for group cohesion and survival. In traditional Maori society, religion was inextricably woven into daily life, social structure, and environmental interaction. Their concept of whakapapa (genealogy) connected all living things—people, plants, animals, and even geographical features—in a vast web of relational ties that extended back to the gods themselves.
This intricate cosmological system provided what evolutionary biologists would recognize as adaptive advantages at multiple levels. The Maori understanding of tapu (sacredness) and mana (spiritual power) established behavioral codes that regulated resource use, social hierarchy, and intergroup relations. These religious concepts functioned similarly to what evolutionary psychologists call costly signaling—demonstrating commitment to the group through expensive behavioral investments that would be hard to fake 1 .

Vaisnava Sahajiya: Sexual Spirituality as Biological Strategy
Vaisnava art depicts divine relationships
While the Maori developed religion as a group survival mechanism, the Vaisnava Sahajiya tradition that flourished in Eastern India from the 16th to 19th centuries represents a fascinating case of religious evolution focused on individual biological fitness through spiritual practice 8 . This tantric Vaishnavism synthesized elements from Vajrayana Buddhism and Gaudiya Vaishnavism, creating a system that viewed sexual union as a path to divine realization.
The Vaisnava Sahajiyas worshipped Radha and Krishna not merely as external deities but as the inner cosmic forms present within all men and women 8 . They developed sophisticated sexual practices aimed at transforming ordinary desire (kama) into pure divine love (prema) .
Evolutionary Advantages of Vaisnava Sahajiya Practices
Enhanced Reproduction
Sacred sexual union encouraged reproductive behavior
Kin Network Expansion
Extended cooperation beyond immediate kinship
Energy Conservation
Control of sexual fluids believed to increase vitality
Gender Equity
Female gurus and balanced partnerships
The Commune Study: Testing Religion's Survival Value
One of the most compelling scientific investigations into religion's evolutionary advantages comes from researcher Richard Sosis, who conducted a systematic analysis of 200 utopian communes in 19th-century America 1 . This natural experiment provided ideal conditions for testing whether religious groups demonstrated greater resilience than their secular counterparts.
Methodology
Sosis and his team compared 88 religious communes with 112 secular communes, carefully tracking their longevity over decades. The researchers documented the specific requirements and sacrifices each community demanded from members, including economic contributions, behavioral restrictions, and participation in rituals.
Results and Analysis
The findings were striking: religious communes significantly outlasted secular ones. While only 6% of secular communes remained after 20 years, 39% of religious communes were still functioning 1 .
| Commune Type | Number Studied | Still Functioning After 20 Years | Percentage Surviving |
|---|---|---|---|
| Religious | 88 | 34 | 39% |
| Secular | 112 | 7 | 6% |
"The sacralization of rules and rituals made them more effective in religious contexts. When behaviors are framed as sacred obligations rather than practical choices, people adhere to them more consistently, strengthening group cohesion and resilience."
Toward a New Synthesis: Biology and Spirituality Intertwined
What emerges from examining both Maori and Vaisnava Sahajiya traditions is a compelling picture of religion as a multifaceted adaptive system. Rather than there being a single evolutionary explanation for religion, different aspects of these traditions may have provided distinct advantages through various mechanisms 1 4 .
Maori Tradition
The Maori example strongly supports the group adaptation hypothesis—their religious beliefs and practices enhanced social cohesion, resource management, and intergroup competition.
- Whakapapa connected all beings
- Tapu and mana regulated behavior
- Costly signaling strengthened commitment
Vaisnava Sahajiya
The Vaisnava Sahajiya case illustrates how religious practices could potentially enhance individual reproductive success and partnership stability while also creating broader cooperative networks.
- Sacred sexuality as spiritual path
- Energy conservation practices
- Gender-inclusive leadership
Essential Research Concepts in Evolutionary Study of Religion
| Concept | Function | Application in Current Analysis |
|---|---|---|
| Costly Signaling Theory | Explains how expensive rituals weed out free-riders and demonstrate commitment | Analyzes Maori tapu restrictions and Vaisnava sexual practices as costly signals |
| Cultural Group Selection | Examines how groups with more adaptive cultural traits outcompete others | Explains differential survival rates of religious vs. secular communes |
| Hyperactive Agency Detection Device (HADD) | Identifies cognitive tendency to perceive purposeful agents behind events | Helps explain origin of supernatural belief systems in both traditions |
Conclusion: The Future of Our Religio-Biological Heritage
The study of religion through evolutionary biology doesn't diminish spiritual experience any more than understanding optics diminishes our appreciation of a sunset.
Both the Maori and Vaisnava Sahajiya traditions, despite their dramatic differences, demonstrate how religious systems can create adaptive advantages at multiple levels—enhancing group cooperation, regulating resource use, promoting stable partnerships, and encouraging investment in future generations. Their endurance across centuries suggests they successfully addressed fundamental human challenges in ways that promoted the survival and flourishing of their adherents.
The Religio-Biological Model
Understanding religion not as a mere accident or evolutionary mistake, but as a potentially powerful force in human survival—one that may continue to shape our future as it has our past.
