Why do black people have different hair? Science explains the genetics and evolution behind curly hair

Scientists reveal Afro-textured hair, common in African populations, is a genetic trait likely shaped by evolutionary adaptation. Research suggests its tightly coiled structure helped early humans regulate body temperature in hot climates by creating a cooling layer near the scalp. Recent studies further support this theory, highlighting its superior protection against solar heat, underscoring the rich genetic diversity of humanity.
