Geedkii ugu da'da weyn kordhaya on dhulkeenna

In 1997, Dzhuliya Hill dhigay rikoor ah tiirka on geedka. Sayidka ayay doonayay inaan ka dhaansado in dhibaatada ilaalinta kaynta dareenka dadweynaha. Sida ay u gaari goolkii this - waa aan la aqoon, laakiin geedka cas Rafaa ka hoos loo gooyay, ayay u suurtagashay in ay badbaadin. Waxaa xusid mudan og in dhirta ku aadan xanuunsado tan iyo cudurada da'da la xiriira, sida ka soo horjeeda dadka. Waqti ka, qayb ka mid ah u dhiman karo, oo tan kalena waxay - si ay u koraan qarniyo badan.

Waxaa laga yaabaa in qof kasta oo inaga mid ah ee carruurnimada ayaa u sheegay in qaar ka mid ah noocyada ay noolaan karaan in boqolaal sano. Si kastaba ha ahaatee, xitaa ma dadka waaweyn oo dhammuna waxay ogaan in geedkii ugu da'da weyn ayaa da 'ah oo ku saabsan 10,000 oo sano. In Sweden, Fuul gran buurta on koraa Old Tjikko, kuwaas oo da'da ayaa loo xisaabiyaa by saynisyahano. Marka ugu horaysa ee aad bilaabay hadalka ku saabsan, da geedka ahaa "kaliya" dhawr kun oo sano. Dabcan, ay jirridda sanad walba la cusbooneysiiyaa, laakiin xididada dhirta ka dhashay 100 qarniyo ka hor.

Su'aashu waxay culumadu waxay leeyihiin muddo dheer jawaabi kari waayeen sida geed dunida ugu da'da weyn ee ay wada qaadi karin si ay u noolaadaan oo dhan isbedelka cimilada ee dunida, laga helay ay sharaxaad ee xaqiiqda ah in Old Tjikko dhintay at muddo waqti go'an, oo ku hoos jira xaalad wanaagsan mar kale soo biqlo. Taasi waa waxa sababay yaqiin xukunka ugu horeysay ee saynisyahano ah oo da'doodu u gran.

Tan iyo afartameeyaha ee qarnigii labaatanaad, waxa uu ahaa jir ah in Wuu istaagay kulankii asalka ah ee Ereyada aan fara badan. Isla mar ahaantaana, isbedel wanaagsan ee xaaladaha cimilada ayaa keentay in xaqiiqda ah in geedka bilaabeen inay soo baxaan.

Ilaa wakhtigii sida in lagu qeexaa da'da saxda ah ee gran, geed dunida ugu da'da weyn la matalo geed Metushelax. Waxaa koraa Reserve Qaranka ee California, laakiin goobta saxda ah waxaa qarsoonna tan iyo dadweynaha. Waxaynu og nahay in uu korayo at sare ah oo ka badan saddex kun oo mitir heerka badda. Magaca warshadda ayaa loo magacaabay ka dib markii qof ee kitaabiga ah, kuwaas oo uu dumo safar of 969 sano. Currently, Metushelax waxaa loo arkaa shaqeeyo ugu da'da on neklonnirovannym meeraha Earth. Sida laga soo xigtay saynisyahano, naftiisa bilaabay in 2831 BC. e.

Qaar ka mid ah cilmibaadhayaasha, sida musharax u ah horyaalka ee "geedka ugu da'da weyn dhulka" riixdo geed intermountain Prometheus. Waxa uu korayo on Mount Wheeler Fiinta oo dalka Mareykanka ah. Ajnabiga warshad tani waxay ahayd in ka badan 5000 sano, laakiin da'da saxda ah oo uu ku hadhay wax qarsoon.

Dalbashada technology ee waqtiga, saynisyahano ayaa muujiyay in geedka ma aha in ka yar 3-4 kun oo sano. In 1964, D. Curry, iyadoo ogolaansho ka mid ah Service Forest Maraykanka (USFS), gooysaan oo geed geed a oo wuu qaybiyaa qaybo in ka dib ayaa loo diray laboratories kala duwan. Currently, qayb ka mid ah Prometheus loo arki karaa in matxafyada kala duwan American. Oo meeshii geedka ugu da'da weyn koray, haatan waxaa weli keliya jiridda ah. Waa maxay ujeedada ay u baabbi'in cilmiga ka qaatay dhirta oo dhan - waa aan la aqoon.
