Why did curly hair evolve?
They suggest that either environmental or sexual selective pressure began acting on hair after humans began dispersing out of Africa, helping shape the wide range of human hair types present today. The limited evidence points to temperature as a factor. Curly hair may help keep the head cool in warm climates.
