A recent study has highlighted that over the past century, men have experienced a more significant increase in height and weight compared to women, influenced by improved living conditions. By analyzing various data sources, researchers found that for every 0.2 point rise in the Human Development Index (HDI), men's height increased by an average of 4cm while women's only increased by 1.7cm. This trend emphasizes the impacts of sexual selection and environmental conditions on physical development, resulting in a notable disparity in body metrics between genders.
The study shows that men have gained height and weight more rapidly than women over the last century, suggesting significant changes in sexual selection.
In terms of improved living conditions, the analysis indicated men's average height increased 4% compared to women's 1.9%, highlighting growing differences between sexes.
