This comprehensive research report offers a rigorous, science-based framework for investigating the potential existence of a large bipedal primate species, such as Bigfoot or Yeti. Moving beyond anecdotal accounts, the analysis systematically applies established principles of comparative primatology, metabolic scaling, and conservation biology to determine the non-negotiable requirements for a large-bodied primate (estimated 150-350 kg) to maintain a viable population in North America and Eurasia.
Discover the essential criteria that must be met, including:
• Energetic Demands: Daily caloric needs of 7,000-11,250 kcal, supporting the need for a highly flexible, omnivorous diet.
• Habitat Criteria: The minimum requirement of 100,000-400,000 km² of contiguous, low-human-density habitat, with a focus on dense forest cover and topographic diversity.
• Population Dynamics: Analysis of Minimum Viable Population (MVP) theory, suggesting a census population of 1,500-2,500 individuals and extremely low population density (0.5-1.5 per 100 km²) in optimal conditions.
• Field Protocol: Detailed, science-based recommendations for field investigators, prioritizing long-term acoustic monitoring, eDNA collection, camera trap arrays, and systematic habitat suitability modeling.
By establishing these stringent biological and ecological baselines, this report provides scientists and researchers with the necessary guidelines to shift the search from speculation to a systematic, falsifiable, and empirically-evaluated investigation.
