No, dhab ahaantii ay si fudud u leeyihiin awoowe caadi ah. In mustaqbalka, laan this u qaybsan yahay laba nooc oo gebi ahaanba kala duwan. Gaar ahaan, maxaa yeelay, kala duwanaanshaha iyo maroodi ah ay awoodaan si ay u noolaadaan, taasoo ka dhigeysa mid xigtadiisa ah ilaa hadda ka dambeeya.

Iyadoo la tixgelinayo inuu bareejeeyo ah oo dhogor, noocan agagaarka 200-300 kun muuqday. Years ka hor. Sida laga soo xigtay cilmi by paleontologists, dalkooda ahaa Siberia. Sidaa darteed, waa helaa Inta badan Muujinaysaan runta ku saabsan noloshooda ah, ayaa la dhigay in this qarkiisa adag. Si kastaba ha ahaatee, wakhtigaas, cimilada halkan ma joogo, dhaxan bay ahayd, oo khafiif ah, dhexdhexaad ah.

Sidee baad u xukumi karaa haddii qof kuwii dhintay dheer?

mammoths cadayni dhintay soo baxay waqti dheer ka hor. Si aad u noqoto more sax ah, wakiilka ugu dambeeyey ee noocyada this ku saabsan 4 kun oo dhintay. Years ka hor. Ma aha la yaab leh in dad badan oo ka shakisan yihiin in saynisyahano ah u soo gudbiso tilmaan faahfaahsan oo xayawaanka, iyo sidoo kale daaha ka mid ah qaababka ay dhaqanka. Ka dib oo dhan, sida lagu xukumi karaa walaxda, taas oo aan dunida oo dhan in ka badan 4 kun. Years?

Well, runta waa in saynisyahan ka dhigaysa sayniska sida paleontology. Waxa ay u ogolaataa iyaga si ay u eegaan fog galay soo dhaafay, ku salaysan oo keliya on hadhaagii xoolaha.

Intaa waxaa dheer, qaar ka mid ah iyaga ka mid ah waxaa si aad u wanaagsan sii raagayaan.

Tusaale ahaan, dhawaan in Taimyr waxaa laga helay oo dhogor bareejeeyo qaboojiyay in block a baraf. Sida laga soo xigtay saynisyahano, ayuu halkaas jiifsaday ugu yaraan 30 kun. Years. Sababo la baraf bakhtigii xayawaan aan giirte, oo sidaas daraaddeed, paleontologists hesho shaybaarka unugyada jilicsan fiican, iyo suufkayga, iyo xataa ku jira caloosha nuxurrada. Sayidka sayniska fursad u helay in ficil ahaan u muujiyo oo dhan qarsoon ee kooxda bakhtiyeen.

soocin kale oo muhiim ah noocyada this ayaa jubbadda qaro weyn, oo ka kooban jidhka oo dhan bahalka. Oo dhererkiisu waa kala duwanaayeen sanadka oo dhan, jidaynayey xayawaanka la qabsato Heerkulka ah. Laakiin xitaa xagaaga u buurbuur ku deldesheen oo ka dhinac ee bareejeeyo iyo mararka qaarkood gaadho 90 cm oo dherer ah. Sida for midabka, ka dibna bahal this lahaayeen timo madow brown iyo mararka qaar madow.

Waxa xiiso leh in, si ka duwan maroodi, bareejeeyo ah oo dhogor lahaa dhego yar. Taas macnaheedu waa in wakiilada casriga ah ee kooxdan ka heleen hadiyadda horumar ka dib markii eynu ee ehelkooda.

Features of bareejeeyo oo dhogor dhaqanka

Maanta, cilmi-waxay aaminsan yihiin in maroodi casri ah ay awoodaan in ay ka caawinto inay xaliyaan qarsoodiga dhaqanka mammoths.

Marka labaad, gudahood pack halkaas joogay madaxda adag ku salaysan matriarchy. Waxaa intaa dheer, inta badan koox bareejeeyo koobnayd oo kaliya carruurta iyo dhadig, halka labka doorbiday nololeed cidla ah.

fikrad kale oo xiiso, saynisyahano u hormarsataan, ku salaysan fataahadda xayawaanka. All mammoths waxay ahaayeen dogob gaaban, sidaas darteed, ma ay heli karto cuntada dhirta dhaadheer.

Iyo ugu khatarsan kuwa wakhtigaas ahaayeen yeyda, maxaa yeelay, waxay ugaadhsanayaan, waxay adhiga habaysan weeraray. Si kastaba ha ahaatee, xitaa iyagu ma ay dhicin inay ku degdegin inaad kulan weyn, iyo weli bahal gaajaysan ka adhi dhallinyarada ugaadhsado wiifto ah.

Laakiin ugaadhsade u cabsi badan ka sii ahaa nin. Fadilnaa sirdoonka, wuxuu ahaa awoodaan in ay jabiyaan cadowga kasta, oo ay ku jiraan sida weyn. A kaydka weyn ee hilibka iyo baruurta sameeyey awowayaashayo ka badan iyo inta ugu badan weeraraan kuwaas xayawaanka si nabad ah.

Sababaha ka lumay ee mammoths

eynu ee bareejeeyo ah oo dhogor - mawduuc ka wada hadleen dhowr sano, ama xataa tobanaan sano. Dhowr mala hormarsataan - ka isbedel heerkulka caalamka inay arrimo aadmiga. Tan iyo xayawaanka ayaa sidoo kale si dhakhso ah lagu dilay, saynisyahano ku jiido dib oo dhan aragtiyo la xidhiidha isbedelka cimilada si tartiib ah ama xasuuqa on qayb ka mid ah nin. Inta badan, sababta ka lumay ee noocyada this waxa uu noqday cudurka baahsaneyd ee ay sababeen la'aanta calcium in cunto xoolaha (tani waxaa daliil u ah natiijooyinka of paleontologists). Like this dhici karto sabab u tahay xaqiiqda ah in heerka biyaha dhulka ayaa si xad dhaaf dhacay, oo waxay iska daayeen inay keenaan dusha xaddiga saxda ah ee macdanta. Laakiin waxaa sidoo kale waa u dooda version ah oo kala duwan sida uu sheegay oo Rafaa dumay aafadaas awood - qaboojinta af badan sabab u ah barakaca of qolof ah dhulka ee.

Sidaas darteed, ku dhowaad dhammaan of mammoths noqday bakhtiyeen ku saabsan 10 kun. Years ka hor. marka laga reebo waxa uu ahaa dadka yar oo xoolaha nool on Wrangel Island. halkaas ayay degeen dhawr kun oo sano ka dheer dhigooda. Si kastaba ha ahaatee, xuduudaha dhulka keentay in xaqiiqda ah in pool hiddo xayawaanka waxaa si buuxda u daalan sababta oo ah isgaarsiinta la xiriira si dhow.
