Sahara mein kabhi hariyali thi? DNA analysis se pata chala!
Aaj kal ke barren Sahara desert mein kabhi lush green savannah thi, yeh sunke aapko vishwas nahi hoga. Lekin 7000 saal purane DNA analysis se yeh sach samne aaya hai. Is analysis se African humid period ke bare mein pata chalta hai, jab North Africa ke log pastoralism karte the. Matlab, woh log animals ko palte the aur ghumantu jeevan vyatit karte the. DNA analysis se un logon ke ancestry ke bare mein bhi pata chala hai.
DNA analysis kya batata hai?
Yeh DNA Sahara desert mein paye gaye remains se extract kiya gaya tha. Isse pata chala ki wahan kabhi greenery thi aur log wahan rehte the. Yeh analysis ek breakthrough hai kyunki isse hum North Africa ke itihaas ke bare mein aur jaan sakte hain.
Kya tha African humid period?
African humid period ek aisa time tha jab Sahara desert mein zyada rainfall hota tha aur wahan greenery thi. Yeh period kareeb 11,000 saal pehle shuru hua tha aur 5,000 saal pehle khatam ho gaya tha. Is period mein North Africa mein kai lakes aur rivers the, jahan aaj barren land hai.
Pastoralism kya hai?
Pastoralism ek aisa lifestyle hai jismein log animals ko palte hain aur unke saath ghumte hain. Yeh log apna khaana, kapda aur rehne ke liye animals par nirbhar rehte hain. African humid period ke दौरान North Africa mein pastoralism kaafi common tha.
Aage kya?
Yeh research bahut important hai kyunki isse hum climate change aur human migration ke bare mein aur jaan sakte hain. Scientists aage bhi research karenge taki hum is period ke bare mein aur zyada information hasil kar sakein. Isse humein future ke liye better prepare karne mein madad milegi.
