What Ancient Humans Did When the Desert Was a Death Trap

Deserts have killed travelers for as long as humans have crossed them — yet ancient humans didn't just survive the world's harshest landscapes, they learned to read them. This video explores how early humans used timing, water logistics, shelter, clothing, and passed-down knowledge to turn one of Earth's deadliest environments into a place they could actually live in. From the "Green Sahara" to the biology of human sweat, here's the real story of how our ancestors beat the heat. Sources: 1.
