vaigyaanik naam

baaladaar gainde ka vaigyaanik naam 'seelodonta ainteekveetaatis​' (Coelodonta antiquitatis) hai. iske jeevavaijnyaaanik vansh (genus, jeenas) 'seelodonta' ka matlab 'khokhala daant' hota hai.[2]

vivran

saaiberiya mein thand se jame hue shavon aur gufaaon ki deevaaron par aadimaanavon dvaara banaai gayi tasveeron se baaladaar gaindon ka roop-rang gyaat hota hai.[3] sar-se-dum tak yeh 10-12 fut (3-4 meter) lamba hua karta tha aur iska vajn 2,700-3,200 kilo hota tha. iski ooainchaai 6.6 fut (2 meter) tak hoti thi. iske sir par do seeng hote the aur aage wala zyaada lamba tha. aage wala seeng 2 fut (61 seinteemeetar) tak lamba ho sakta tha.[4] iske kaan chhote, taange moti aur jism bhaari-bharakam hua karta tha. gufa-kala mein kabhi-kabhi aage aur peechhe ki taangon ke beech gaadhe rang ki ek dhaari dikhaai jaati hai lekin yeh gyaat naheen hai ki vaastav mein sabhi baaladaar gaindon mein yeh dhaari thi ki naheen. bada shareer aur ghane baal hone se yeh apne shareer mein barfeele haalaat mein bhi garamaahat banaae rakh sakta tha.[5]

jaati ka vinaash

vaigyaaniko ko sahi tarah gyaat naheen hai ki baaladaar gaindon ke khtm ho jaane ka kya kaaran tha. ek dhaarana hai ki jaise-jaise aadhunik maanav aur niandarathal maanav inka shikaar karne lage, dheere-dheere yeh vilupt ho gaye.[6] ek anya dhaarana hai ki jab poorv himyug samaapt hone laga to mausam garam hua aur yeh nae vaataavaran ki paristhitiyon mein jeevit na rah paae. ek teesari dhaarana yeh bhi hai ki is jaati mein ek aisi nai jaanleva beemaari fail gayi jisne poori jaati hi teji se khtm kar daali.[7] vivaad jaari hai.
