Kubatira Kurwara? Zvichida mhosva yenyu Neanderthal majini

Kana kudzivisa maruva emusango, Citrus michero, chocolate kana nzungu nokuda neutachiona, unotsamwira yenyu Neanderthal madzitateguru, kana kuti, majini avo.

Apo tine Neanderthal majini?

Zvinozivikanwa kuti Neanderthals uye Cro-Magnons denisovtsy (madzitateguru evanhu ano) - vari vatatu vakasiyana mhuka. Saka, nhasi, vamwe vanhu kuzviratidza kuva kana Neanderthal kana Denisovskoe majini?

The coexistence aya akasiyana kwemarudzi akanga pfupi zvikuru, asi achiri zvakakwana kugara pamwe chete nenharaunda. Mukuwedzera hondo uye pachedu kurwisana nyaya vakavhengana michato, uye vana vakaberekwa navo vakanga VaNefirimu - ivo vatakuri genome somunhu mumwe, uye vamwe. Pashure pakasvika Cro-Magnon uye Neanderthal Denisovskoe vanhu kunonyangarikawo kubva pachiso chenyika, achisiya murume ano 4% majini avo.

Chii ukama takaberekwa majini kuti haupindirani nezvimwe zvinhu?

Chisimbwa - maitiro of rokuzvidzivirira kuitika. Kana uine Kurwara, hazvirevi kuti iwe une simba rokuzvidzivirira, panzvimbo yaizvozvi. Ichi chikamu chiduku kubva genome, iwe nhaka Neanderthal tateguru, akaita wako zvirwere zviri vakasvinurira chaizvo uye achikurumidza mhirizhonga. Naizvozvo, zvazvinoita kwete chete kune nemavhairasi uye zvirwere, asi zvishoma dambudziko akafanana mukume uye yemishambangwena Zvinhu Zvisina Basa.

Munhu wese zvake ari Caucasian rudzi, nhaka kubva 1 kusvika 6% of genome pakati Neanderthal madzitateguru. Sei hakuna chinhu sema maitiro zvachose? Vanodzidza uye nyanzvi dzinoongorora dzakaratidza kuti Neanderthal murume zvirwere mhinduro kunge vakava nani zvikuru kupfuura Cro-Magnons. Neanderthal majini nhaka vanhu ano, rinonyatsooneka zvainoita Toll-zvakadai receptors, izvo kudzora tinozvarwa zvirwere muviri cellular Kupindura mikana yakawanda yokukurudzira uye. Nokudaro, kumusoro ari chikamu nhaka genome, chikuru mukana neutachiona.

Modern nemagene tsvakurudzo

In richangopfuura reShanduro American Journal of Human genetics, maviri akazvimirira uye chokuita mumwe zveBhaibheri vakasvika chete mhedziso; ari Neanderthal uye Denisovskoe majini zvikuru zvakasimba wakaratidzwa zvirwere.

Dr. Michael Dannemann yave kudzidza zvinokonzerwa yakatotsakatika zvemamiriro munhu DNA. Akasvika mhedziso kuti Toll-kufanana receptors vari vazhinji sei kubudikidza allele pamusoro genome pakati Neanderthals. Maererano nokutsvakurudza ake, 11 kusvika 51% vanhu vari hamuzi nhangemutange African, vane pane imwe allele of Neanderthal. Pamwero mukuru kubva muzana dzinosiyana-siyana zvichienderana rwevanhu.

A kudzidza yechipiri vakaperekedza Dr. Luis QUINTANA-Mursi. Kudzidza Toll-kufanana receptors chete chikamu basa rake, iro rinotarisira - kufunga shanduka majini anokonzera zvirwere kuvanhu gadziriro. Maererano naye, vakawanda vedu rokuzvidzivirira yave kuchinja mumakore 13.000 makore - munguva apo vanhu kuchinja zvishoma nezvishoma nzira zvokudya, uchifamba kubva kunovhima uye achiunganidza nokurima uye mhuka minda.
