Wahlala eminyakeni engama-6,000 XNUMX eyedlule esiqhingini esikude endaweni manje eyiDenmark futhi manje sesiyakwazi ukuthi kwakunjani. Wayenesikhumba esimnyama, izinwele ezimnyama nsundu, namehlo aluhlaza okwesibhakabhaka.
Akekho owaziyo ukuthi kwakungubani igama lakhe nokuthi wenzani, kepha ososayensi abakha kabusha ubuso bakhe bamnike igama: uLola.
U-Lola - indaba engakholeki yowesifazane we-Stone Age
Owesifazane we-Stone Age, i-physiognomy kaLola angaziwa ngenxa yemikhondo ye-DNA ayishiye "kushungamu", ucezu lwetiyela olwafakwa emlonyeni eminyakeni eyizinkulungwane edlule neyalondolozwa isikhathi eside ngokwanele ukuthola ikhodi yofuzo lwayo .
Ngokusho kwephephabhuku i-Nature Communications, lapho ucwaningo lwashicilelwa khona ngoDisemba 17, 2019, kwakungokokuqala ngqa ukuthi kukhishwe ufuzo lomuntu lwakudala entweni okungeyona eyethambo.
Ngokusho kososayensi besifundo esenziwa e-Hannes Schroeder base-University of Copenhagen, ucezu lwetiyela olwalusebenza njenge "chewing gum" luvele lwaba umthombo obaluleke kakhulu we-DNA yasendulo, ikakhulukazi ngezikhathi lapho kungekho khona izidumbu zomuntu itholakele.
"Kuyamangaza ukuthi ngithole ufuzo lomuntu lwakudala oluphelele kokunye okungelona ithambo," kusho abacwaningi.
Yavelaphi ngempela i-DNA?
I-DNA ibibhajwe esigaxeni se-pitch esinsundu esimnyama, esenziwe ukushisa ibark birch, ebisetshenziswa ngaleso sikhathi ukunamathisela amathuluzi wamatshe.
Ukuba khona kwezimpawu zamazinyo kusikisela ukuthi le nto yayihlafunwa, mhlawumbe ukuyenza ibelula, noma mhlawumbe ukuqeda izinyo noma ezinye izifo.
Yini eyaziwayo ngoLola?
Yonke ikhodi yofuzo yabesifazane, noma i-genome, yakhishwa futhi yasetshenziswa ukuthola ukuthi kungenzeka ukuthi injani.
ULola wayexhunyaniswe nezakhi zofuzo kakhulu kubazingeli-abaqoqi bezwekazi laseYurophu kunalabo ababehlala enkabeni yeScandinavia ngaleso sikhathi futhi, njengabo, wayenesikhumba esimnyama, izinwele ezimnyama nsundu namehlo aluhlaza okwesibhakabhaka.
Kungenzeka ukuthi wayevela kubantu ababehlala eNtshonalanga Yurophu ngemuva kokususwa kwamaqhwa.
Waphila kanjani uLola?
Iminonjana ye-DNA etholakala "kushungamu" ayigcinanga ngokunikeza imikhondo ngempilo kaLola, kodwa futhi nemikhondo ngempilo yaseSaltholm, isiqhingi saseDenmark oLwandle iBaltic lapho batholakala khona.
Ososayensi bakhombe amasampula ezakhi zofuzo we-hazelnut ne-mallard, bephakamisa ukuthi babeyingxenye yokudla ngaleso sikhathi.
"Yisiza esikhulu samatshe aseDenmark eDenmark kanti okutholwe yimivubukulo kusikisela ukuthi abantu ababehlala kule ndawo babesebenzisa kakhulu izinsizakusebenza zaseNeolithic, okuyisikhathi lapho kwethulwa khona okokuqala ezolimo nezilwane ezifuywayo eningizimu yeScandinavia," kusho uThis Jensen wase-University of Copenhagen.
Abaphenyi baphinde bakhipha i-DNA ezintweni ezincane ezivaleleke “kushungamu.” Bathola amagciwane abangela i-glandular fever ne-pneumonia, kanye namanye amagciwane amaningi kanye namagciwane akhona ngokwemvelo emlonyeni kodwa angabangeli izifo.
Imininingwane ngamagciwane asendulo
Abaphenyi bathole ukuthi imininingwane egcinwe ngale ndlela inikeza isithombe sezimpilo zabantu futhi inikezela ngolwazi ngozalo lwabo, indlela abaziphilisa ngayo kanye nempilo yabo.
I-DNA ekhishwe kushungamu iphinde inikeze ukuqonda kokuthi amagciwane omuntu aguquke kanjani eminyakeni edlule. Futhi lokho kusitshela okuthile ngokuthi zisabalale kanjani nokuthi zavela kanjani eminyakeni edlule.
