Ocwaningweni olusha, ososayensi basebenzisa izinkulungwane zokulandelana kofuzo lomuntu. Imiphumela ishicilelwe kumagazini iSayensi.
Ososayensi benze isihlahla somndeni ukuze sonke isintu sifinyeze ukuthi bonke abantu abaphilayo namuhla bahlobana kanjani kanye nokhokho bethu basendulo. Ukuyakha, abacwaningi bahlunga izinkulungwane zokulandelana kofuzo oluqoqwe kubantu banamuhla nabasendulo. Basebenzisa nedatha evela ezihlotsheni zabantu zasendulo. Wonke ama-genomes avela kubantu abangu-215 abahlakazekile emhlabeni jikelele.
Besebenzisa i-algorithm yekhompiyutha, ososayensi bakhombe amaphethini ahlukene okuhlukahluka kofuzo ngokulandelana, begqamisa lapho agqagqana khona futhi ahluke. Ngokusekelwe kumaphethini, abacwaningi badwebe imigqa yetiyori yokwehla phakathi kwama-genome.
Ukuze kwakhiwe uhlu lozalo lwabantu oluhlangene, abacwaningi baqale bahlanganisa idatha evela kumasethi edatha amakhulu amaningi omphakathi, okuhlanganisa i-1000 Genomes Project, i-Human Genome Diversity Project, kanye ne-Simons Genome Diversity Project. Ukuthola idatha kubantu basendulo bekunzima kakhulu, kodwa ososayensi bathole i-hominin genomes yasendulo engu-8 ephezulu. Phakathi kwawo kukhona ama-genome amathathu e-Neanderthal, enye yawo eneminyaka engaphezu kuka-100,000 74,000 ubudala; I-Denisovan genome, iminyaka engu-82,000 kuya ku-4,600; kanye nezakhi zofuzo ezine ezivela emkhayeni wenuzi owawuhlala ezintabeni zase-Altai eRussia eminyakeni engaba ngu-XNUMX XNUMX edlule.
Ngemva kokuqoqa isihlahla somndeni, ososayensi benza ucwaningo lwendawo. Baqinisekise ukufuduka kwabantu e-Afrika futhi bathola nobufakazi obungaba khona bokusebenzelana phakathi kwama-Homo sapiens nama-hominin angasekho.
Qaphela: Umugqa ngamunye kulo mfanekiso umele ubudlelwano besizukulwane sedlozi ohlwini lozalo olusha lwezakhi zofuzo zesimanje nezakudala. Isithombe: Uhlu lozalo oluhlanganisiwe lwezakhi zofuzo zesimanje nezakudala, Isayensi (2022). I-Doi: 10.1126/science.abi8264
