ANCESTRAL & EVOLUTIONARY BIOLOGY

Modern Life vs Ancient Genes.

The mismatch between our 2-million-year-old genome and our 50-year-old environment is the root of virtually every modern chronic disease. This domain explores how returning to ancestral patterns of movement, light, food, and community resolves biological conflict.

Sedentary Sickness and the Movement Requirement: Why Modern Ergonomics Cannot Replace Ancestral Physical Variability

Human physiology is designed for constant, low-intensity movement punctuated by brief bouts of high intensity. This article explains why 'the gym' is a poor substitute for ancestral movement and how chronic sitting fundamentally alters our metabolic health.
