A new analysis reveals that men are evolving at twice the rate of women, influenced by improved living conditions, including nutrition and healthcare. The study examines data from over 135,000 individuals across 62 countries, linking higher human development index (HDI) scores to increased male height and weight. For every 0.2 increase in HDI, men grew 1.5 inches and gained 14 pounds. This trend aligns with evolutionary theories, where male traits signal health and strength, impacting mate selection, while women's evolution seems less responsive to environmental factors.
The findings suggest men are evolving faster than women, with better living conditions leading to increased height and weight, affecting attractiveness and mate selection.
Researchers analyzed data from over 135,000 individuals across various countries, finding a direct correlation between improved living conditions and significant evolutionary changes in men.
