Vishu Choudhary
Due to natural selection, people who lived in areas of intense sunlight developed dark skin colouration to protect against ultraviolet (UV) light, mainly to protect their body from folate depletion. Evolutionary pigmentation of the skin was caused by ultraviolet radiation of the sun. 🤓👍

बहुत सारे कारण है अफ्रीका के लोगों के काले होने के एक तो वहां बहुत ज्यादा गर्मी पड़ती है और जिसके कारण उनका रंग काला पड़ जाता है और दूसरा सूर्य की पराबैंगनी किरणों के कारण स्क्रीन का पिगमेंटेशन होता है जिससे उनका रंग काला पड़ जाता है और नेचुरल साइड इफेक्ट

You are right that there is very hot environment in Africa but you missed this point…..due to excess exposure in sunlight, the secretion of melatonin is increased in them, .
