Marc Bates, MPH, announces the release of his latest YouTube video presenting archaeological evidence that contradicts the widely accepted belief that humans evolved as omnivores. The research reveals what Bates terms "the 1.5 million year carnivore gap" in human evolutionary history.

The video examines archaeological data showing meat-processing tools appeared 1.5 million years before plant-processing technology emerged. This timeline suggests humans functioned as facultative carnivores for the majority of their evolutionary development.

"When I first encountered the archaeological data showing that meat-processing tools appeared over 1.5 million years before plant-processing technology, my immediate reaction was one of profound confirmation," Bates stated. "Humans are not just opportunistic omnivores - we are biologically optimized for meat."

The research highlights isotopic analysis revealing early humans possessed nitrogen signatures similar to top predators. Additional evidence includes anatomical features such as high stomach acidity and small colons optimized for animal food digestion rather than fiber fermentation.

Bates connects these evolutionary findings to modern metabolic health challenges. He argues that current dietary guidelines have inverted the ancestral nutritional model by promoting grain-based diets over animal-based nutrition.

"Modern dietary guidelines treat the last 10,000 years of agriculture as the default for human nutrition, while ignoring the 2.5+ million years during which our physiology was shaped by a radically different, animal-based diet," Bates explained.

The video addresses implications for contemporary health outcomes and metabolic dysfunction. Bates suggests that understanding human evolutionary diet patterns provides insights for addressing chronic health conditions including obesity and diabetes.
