Perfectly Preserved Woolly Rhino Emerges from Melting Siberian Permafrost
Tasawwur karein ke aap waqt mein hazaron saal peechay safar kar ke Ice Age mein pohanch gaye hain. Siberia ki pighalti hui barf (permafrost) ne science ki duniya ke liye bilkul yahi mumkin bana diya hai. Haal hi mein, Russian scientists ne Yakutia ke ilaqay mein ek naujawan (juvenile) woolly rhinoceros (baalon wala gainda) ki laash daryaft ki hai jo is qadar mukammal halat mein hai ke dekhne walay dang reh gaye. Yeh barf mein jama janwar na sirf ek anokhi daryaft hai, balke yeh humein Ice Age ki duniya mein jhaanknay ka ek be-misaal mauqa faraham karta hai.
A Discovery Frozen in Time (Waqt Mein Munjamid Ek Daryaft)
Yeh hairat angez daryaft Siberia ke darya Tirekhtyakh ke qareeb hui, jahan climate change ki wajah se musalsal pighalnay wali zameen ne is qadeem raaz se parda uthaya. Scientists ke mutabiq, yeh rhino 20,000 se 32,000 saal purana hai. Iski hifazat (preservation) ka aalam yeh hai ke iske jism par uski narm, bhuri oon (fur), khaal (skin), khur (hooves), aur yahan tak ke jism ke androoni aza (internal organs) jaise ke aantain (intestines) bhi kaafi had tak mehfooz hain. Yeh ek intehai nayab (rare) mauqa hai kyunke narm tissues (soft tissues) waqt ke sath ghul jaate hain aur fossils mein sirf haddiyan baaqi rehti hain.
The Story of a Young Rhino (Ek Naujawan Gainday Ki Kahani)
Mahireen (experts) ne is barf mein jama janwar ki kahani ko jornay ki koshish ki hai. Unka andaza hai ke is rhino ki umar maut ke waqt 3 se 4 saal ke darmiyan thi. Sab se qawi imkaan (strongest possibility) yeh hai ke yeh bechara ghalti se kisi darya ya daldal mein doob gaya hoga. Siberia ki shadeed sardi ne iske jism ko foran baraf mein munjamid (freeze) kar diya, jiski wajah se yeh hazaron saal tak galnay sadnay se mehfooz raha. Kuch shawahid (evidence) is taraf bhi ishara karte hain ke iske jism ko Ice Age ke deegar shikaari janwaron ne thora bohat khaya bhi tha, jo iski zindagi ke aakhri lamhaat ki ek jhalak faraham karta hai.
Climate Change: A Double-Edged Sword (Climate Change: Ek Do-Dhari Talwar)
Yeh daryaft aur is jaisi deegar daryaftein (jaise woolly mammoths, ghaar ke reechh, aur sher ke bachay) darasal climate change se nikalnay walay fossils hain. Jese jese Arctic ki baraf pighal rahi hai, yeh qadeem “time capsules” samne aa rahe hain. Yeh ek do-dhari talwar hai: ek taraf, climate change hamari zameen ke liye ek sangeen khatra hai, lekin doosri taraf, iski wajah se humein apne maazi (past) ke baray mein aisi anmol maloomat mil rahi hain jo pehle kabhi mumkin nahi theen.
A Window to the Ice Age (Ice Age Mein Jhaanknay Ki Khirki)
Yeh woolly rhino sirf ek janwar ki laash nahi, balke Pleistocene دور (epoch) ke ecosystems ko samajhne ke liye ek khirki hai. Is daryaft se scientists ko us daur ke mahol, rhino ki biology, uski ghiza, aur uske khatmay (extinction) ki wajuhaat ke baray mein qeemti maloomat milengi. Iske DNA par ki jaane wali genetic analysis humein evolution ke amal ko behtar taur par samajhne mein madad degi. Har naya barf mein jama janwar jo is tarah milta hai, woh hamari zameen ki tareekh ke puzzle ka ek naya tukra hota hai.
