Ka lilemo tse 'maloa, Daniella Fenton, mofuputsi le mongoli, o' nile a etsa lipatlisiso tse tebileng ka tšimoloho ea pele ea moloko oa batho le ho potlakisa ha eona ka tšohanyetso khōlong ea boko haufi le lilemo tse 800,000 tse fetileng; mosebetsi oa hae o hlahisitse tšenolo e kholo:
Homo sapiens ke litloholo tsa bo-ramahlale ba khale ba tlileng lilemo tse 780,000 tse fetileng ka lesoba la seboko ho tsoa Sehlopha sa linaleli sa Pleiades.
Mofuputsi oa Australia, setsebi sa mali a lipere le polelo ea liphatsa tsa lefutso o ile a sibolla liphetoho tse ngata tsa liphatsa tsa lefutso tse khethollang batho ho mefuta ea hona joale ea litšoene, tseo tse ling tsa tsona e leng tse tsotehang hoo li ka hlalosoang feela ke boenjiniere bo tsoetseng pele ba liphatsa tsa lefutso.
Buka ea Daniella Fenton, 'Batho ba Hybrid: Bopaki ba Saense ba Lefa la Rona la Bojaki la Lilemo Tse 800,000,' e hlalosa ka tatellano ea liphetoho tse ngata liphatseng tsa lefutso tse amanang le khōlo ea boko, kaho ea methapo ea kutlo, le ho lokisa litaba. Liphatsa tsa lefutso tse hlahang ka tšohanyetso li entsoe ka ho feletseng ho seo ho thoeng ke "DNA e se nang thuso" 'me likaroloana tsa liphatsa tsa lefutso tse ntšitsoeng, tsa kopitsoa, 'me tsa kenngoa hape ke mehlala ea liphetoho tsena.
Fenton o bona kopanyo e ke keng ea hlalosoa ea Chromosome-2 hoo e ka bang lilemo tse 780,000 tse fetileng, ka nako e le 'ngoe le liphetoho tsena tse ling, e le bopaki bo bongata ba ho qhekella ha linaha tse ling. Kopano ena e etsahala mefuteng eohle ea batho ba nang le bokooa bo boholo, ho kenyeletsoa Neanderthals le Denisovans, empa eseng mefuteng e meng ea litšoene.
O pheha khang ea hore ho kopanngoa ha chromosome-2 e ka be e bile phoso ea nako e le 'ngoe e neng e tla fela molokong o latelang, kapa e ka be e bakile sechaba se senyenyane sa batho ba nang le li-chromosome tse 46 har'a palo e kholo ea batho ba 48. Ho e-na le hoo, phetoho ena e ile ea bonoa ho batho bohle lilemong tse 780,000 XNUMX tse fetileng.
Sena, ho ea ka Fenton, se fana ka maikutlo a ka ho hlaka hore ho kopanngoa ho bile le molemo o moholo le hore ho hlahile ka tšohanyetso ho palo e kholo ea batho (ka boomo), ho lumella chromosome-2 hore e be tšobotsi e sa feleng le e hlaheletseng. Sena ha se tsamaellane le liphetoho leha e le life tse tsejoang tsa tlhaho liphatseng tsa lefutso tsa motho.
"Motho e mong o ile a hlahisa moloko oohle oa balekane ba tsoalisang ba nang le motsoako oa chromosome-2," Fenton oa hlalosa. "Phetoho ea chromosomal e ka ba le phello khōlong ea boko, tsamaiso ea 'mele ea ho itšireletsa mafung le mesebetsing ea pelehi."
Batho le bona ba na le liphetoho tse ikhethang gene FOXP2, e fetotseng likhokahano tsa synaptic le ho ntlafatsa bokhoni ba rona ba ho fetola liphihlelo tse ncha hore e be mekhoa e tloaelehileng; sena se bile le tšusumetso e khōlō bokhoning ba rōna ba ho bua puo e nang le moelelo.
Ho ea ka Fenton, phetoho ena ha e e-s'o bonoe ho litšoene tse ling, 'me e fana ka maikutlo a hore baqapi ba rona ba rerile hore re khone ho fumana mekhoa e mecha ea kamehla, haholo-holo tšebeliso ea puo.
“Hase feela liphetoho tsa liphatsa tsa lefutso lilemong tse 780,000 XNUMX tse fetileng tse re bolellang hore Homo sapiens ke mofuta o entsoeng ke libōpuoa tse sa tloaelehang; re boetse re hloaile lintho tse bonahalang tse siiloeng ke batho bana ba linaleli, e leng lisebelisoa tsa nako e tšoanang ka nako,” Fenton o boletse.
