Tlhahlobo e fana ka maikutlo a hore mohlomong moholo-holo ea tšoanang oa lipuo tsa Indo-European, tse kenyelletsang Senyesemane le Sanskrit, e kanna ea ba e ne e buuoa lilemong tse 8,100 tse fetileng.
Bo-rasaense, ho akarelletsa le ba Max Planck Institute for Evolutionary Anthropology, Jeremane, ba boletse hore lipatlisiso tsa bona ke “katleho e khōlō” ea ho utloisisa qaleho ea lipuo tsa Indo-European, e leng phehisano e ileng ea tsoela pele ka lilemo tse ka bang makholo a mabeli.
Ho ’nile ha hlahisoa likhopolo tse peli bakeng sa ho hlalosa tšimoloho ea lelapa la lipuo tse sebelisoang hona joale ke hoo e ka bang halofo ea baahi ba lefatše.
Khopolo ea Steppe e fana ka maikutlo a hore qaleho ea sena e ka saloa morao ho ea sebakeng sa Pontic-Caspian Steppe hoo e ka bang lilemo tse 6,000 tse fetileng.
Khopolo ea "Anatolian" kapa "temo" e fana ka maikutlo a hore tšimoloho ea ntho e amana le ho qala ha temo lilemong tse ka bang 9,000 tse fetileng.
Leha ho le joalo, lipatlisiso tsa pejana mabapi le lelapa la puo ea Indo-European li hlahisitse liphetho tse fapaneng ka lebaka la ho se nepahale le ho se lumellane ho itseng ka har'a data e sebelisitsoeng.
Bakeng sa ho sebetsana le likhaello tsena, sehlopha sa litsebi tsa lipuo tse 80+ ho tsoa lefats'eng ka bophara li ile tsa bokella mantsoe a mantlha ho tsoa lipuong tse 161 tsa Indo-European, tse kenyelletsang lipuo tse 52 tsa khale kapa tsa nalane.
Tlhahlobo ea morao tjena, e hlahang ho Science, e ile ea batlisisa hore na lipuo tsa khale tse ngotsoeng, tse kang Selatine sa Classical le Vedic Sanskrit, ke tsona tse tlang pele ho lipuo tsa kajeno tsa Romance le Indic, ka ho latellana.
Bafuputsi ba entse tlhahlobo ea tšimoloho e arolelanoang ea lexicon ea mantlha ka lipuo tse 100 tsa hajoale le lipuo tse 51 tsa khale.
Ho bonahala, ho latela lipatlisiso, hore lelapa la puo ea Indo-European le bile teng ka lilemo tse 8,100 le hore lilemong tse 7,000 tse fetileng, makala a mahlano a maholo a ne a se a arotsoe ho lona.
Ho ea ka sengoli-'moho Russell Gray, tatellano ea liketsahalo tsa thuto e ntse e le matla ha e lekoa khahlanong le mefuta e sa tšoaneng ea phylogenetic le tlhahlobo ea kutloisiso.
Ngaka Gray o ile a tiisa hore motsoako oa DNA ea khale le phylogenetics ea puo e ka fana ka karabo ho enigma ea khale ea Indo-European, e leng motsoako oa temo le menahano ea Steppe.
Ho ipapisitsoe le lipatlisiso tsa morao-rao, ho hlahisitsoe khopolo-taba e nyalisitsoeng bakeng sa ho qala lipuo tsa Indo-European. E fana ka naha ea mantlha e ka boroa ho Caucasus le lehae la bobeli ho Steppe, moo lipuo tse ling tsa Indo-European li fihlileng Europe ka ho falla ha batho ba Yamnaya le Corded Ware.
Paul Heggarty, motlatsi oa thuto, o boletse hore lintlha tsa morao-rao tsa DNA tsa khale li supa lekala la Anatolian la Indo-European le tsoang kae-kae haufi le arc e ka leboea ea Fertile Crescent, ho fapana le Steppe.
Dr. Heggarty o ile a etsa tlhahiso ea hore topology ea lelapa la puo le matsatsi a ho arohana ha meloko a supe makala a mang a ka 'nang a ata ho tloha sebakeng seo ka ho toba, eseng ka Steppe.
