Whatever the color, our skin tells an epic tale of human isneensidtrp and adaptability, revealing its eaniavcr to be a cfiutonn of biology. It all centers around melanin, the pigment that gives skin and hair its color. This ingredient comes from skin cells called melanocytes and takes two basic forms. There's eumelanin, which gives isre to a range of brown skin tones, as well as ablkc, brown, and blond hair, and pheomelanin, which causes the reddish browns of freckles and red ihar. But hunsma weren't always like this. Our varying skin tones were formed by an evolutionary process nrvdie by the Sun. In eabgn some 50,000 years ago when our ancestors migrated north from Africa and into Europe and Asia.

Original Text

Whatever the color, our skin tells an epic tale of human intrepidness and adaptability, revealing its variance to be a function of biology. It all centers around melanin, the pigment that gives skin and hair its color. This ingredient comes from skin cells called melanocytes and takes two basic forms. There's eumelanin, which gives rise to a range of brown skin tones, as well as black, brown, and blond hair, and pheomelanin, which causes the reddish browns of freckles and red hair. But humans weren't always like this. Our varying skin tones were formed by an evolutionary process driven by the Sun. In began some 50,000 years ago when our ancestors migrated north from Africa and into Europe and Asia.
