This source explores the evolutionary history of human skin, arguing that dark pigmentation was the original and essential biological default for our species. Approximately 1.2 to 2 million years ago, ancient humans lost their protective fur to develop a sophisticated sweating system that allowed for elite endurance hunting in intense heat. To shield bare skin from lethal UV radiation and protect vital nutrients like folate, our ancestors evolved melanin-rich skin as a necessary survival mechanism. Research into the MC1R gene suggests that every human was dark-skinned for nearly 99% of our history, making lighter tones a very recent adaptation to northern climates. Ultimately, the text illustrates that dark skin served as the foundational keystone that enabled the development of the modern human body and its unique capabilities.
