MunaNovember 2013, masayendisiti akawana imwe yeDNA yekare kudarika yepasi rose, ine humbowo hwemhando isingazivikanwi, kubva pamapfupa echidya ane makore 400,000. DNA kubva kumadzitateguru evanhu aya ane mazana ezviuru zvemakore anoratidza maitiro akaoma ekushanduka-shanduka mumavambo eNeanderthals uye vanhu vemazuva ano. Pfupa nderemunhu, asi rine 'ALIEN DNA'. Kuwana uku kunoshamisa kwakaita kuti masayendisiti asava nechokwadi nezvose zvaanoziva nezvokushanduka-shanduka kwevanhu.
Iyo 400,000-year-old genetic material inobva kumapfupa akave akabatanidzwa neNeanderthals muSpain - asi siginicha yaro inonyanya kufanana neyevanhu vekare vakasiyana kubva kuSiberia, inozivikanwa seDenisovans.
Anopfuura zviuru zvitanhatu zvisaririra zvevanhu, zvinomiririra vanhu makumi maviri nevasere, zvakatorwa kubva panzvimbo yeSima de los Huesos, imba yakaoma-kusvika-kubako iri makiromita makumi matatu pasi pedenga kuchamhembe kweSpain. Zvisaririra zvacho zvaiita sedzakanyatsochengetedzwa, tichitenda chimwe chikamu chetembiricha yebako iri isina kukanganiswa nguva dzose uye mwando mukuru.
Vatsvakurudzi vakaita ongororo vakati zvavakawana zvinoratidza "chisungo chisingatarisirwi" pakati pemhando mbiri dzehama dzedu dzakatsakatika. Kuwanikwa uku kwaigona kupaza chakavanzika - kwete chete kune vanhu vekutanga vaigara mubako rinozivikanwa seSima de los Huesos (chiSpanish che "Gomba reMabhonzo"), asi kune vamwe vasinganzwisisike vagari vemo. Pleistocene epoch.
Ongororo yapfuura yemapfupa kubva mubako yakaita kuti vatsvakurudzi vafunge kuti vanhu veSima de los Huesos vaiva nehukama hwepedyo neNeanderthals pamusana pemaitiro avo emakumbo. Asi iyo mitochondrial DNA yakanga yakanyanya kufanana neiyo yeDenisovans, vanhu vepakutanga vaifungidzirwa kuti vakaparadzana kubva kuNeanderthals makore anosvika 640,000 apfuura.
Masayendisiti akawanazve kuti 1 muzana yeDenisovan genome yakabva kune imwe hama isinganzwisisike inonzi "super-archaic human" nenyanzvi. Zvinofungidzirwawo kuti vamwe vanhu vemazuva ano vanogona kubata 15 muzana yenzvimbo idzi dzemajini e“super-archaic”. Nokudaro, chidzidzo ichi chinoratidza kuti vanhu veSima de los Huesos vakanga vane hukama hwepedyo neNeanderthals, Denisovans uye nehuwandu husingazivikanwi hwevanhu vepakutanga. Saka, tateguru asingazivikanwi uyu angava ani?
Mumwe anogona kukwikwidza anogona kunge ari Homo erectus, tateguru akafa aigara muAfrica makore anenge miriyoni apfuura. Dambudziko nderekuti hatina kumbowana H erectus DNA, saka chakanyanya chatinogona kuita kufungidzira panguva ino.
Kune rimwe divi, vamwe vaongorori vakabudisa pfungwa dzinonakidza chaizvo. Vanoti izvo zvinonzi 97 muzana yezvisiri-coding sequences muDNA yevanhu hazvisi zvishoma pane genetic. hurongwa hwehupenyu hwekunze kwenyika mafomu.
Maererano navo, munguva yakapfuura, DNA yevanhu yakanga yakagadzirwa nemaune neimwe rudzi rwemhando yepamusoro yekunze kwepasi; uye "super-archaic" asingazivikanwi tateguru wevanhu veSima de los Huesos anogona kuva ufakazi hweiyi mhindumupindu yokugadzirwa.
Kubatana kwekunze kwenyika kana rudzi rwevanhu rusingazivikanwe, chero zvazvingava, zvakawanikwa zvinongowedzera kuomesa nhoroondo yekushanduka-shanduka kwevanhu vemazuva ano - zvinogoneka kuti panogona kunge paine vanhu vakawanda vanobatanidzwa. Izvo zvisinganzwisisike, izvo zvakavanzika uye varipo (mukati medu) kwemamiriyoni emakore.
