Pfupisa nyaya yacho:  Mumwe musayendisiti akataura kuti tateguru vevanhu vangadaro vaiva nemakumbo. Zvisikwa zvaigara mugungwa makore 635 kusvika kumamiriyoni 541 akapfuura, izvo vanhu nedzimwe mhuka zvakabva mazviri, sezviri pachena zvakanga zvine nhengo dzomuviri dzinoshanduka-chinja uye gadziriro yetsinga dzakaoma kunzwisisa. Zvinoita sokuti zvinotsigira imwe pfungwa yokuti madzitateguru edu aiva zvisikwa zviri nyore zvikuru, zvakaita semakonye. Mumwe musayendisiti wokuRussia anoti tateguru vekare vevanhu vaiva nemapendekete. Chimwe chisikwa chakadaro chinogona kuonwa pakati pomufananidzo uyu. Dzakararama anopfuura makore mamiriyoni 540 akapfuura uye dzaiashandisa nokuda kwezvokudya. Zvingangodaro kuti vaivawo nehurongwa hwepfungwa hwakaoma kunzwisisa sezvatinoita nhasi. Tsvakurudzo yazvino uno yakaitwa naDr Elena Temereva weDhipatimendi reInvertebrate Zoology paFakisheni yeBiology yeLomonosov Moscow State University. Mazuva ano, vanhu nezvimwe zvisikwa zvakawanda zvine mativi maviri akaenzana - tinonyatsoona kumusoro nokudzika, uye kuruboshwe nokurudyi. Zvisinei, madzitateguru edu ari kure mazana emamiriyoni emakore akapfuura akanga asiri, mazhinji awo achifungidzirwa kuva zvisikwa zvakafanana netsviyo zvaishambira mumakungwa kana kuti kufamba pasi pegungwa. Kudzikama kwemamiriro okunze kungave kwakaita kuti vanhu vokutanga vapinde muEurope yokuMadokero makore 1,4 miriyoni apfuura, kunoratidza imwe ongororo itsva. Vatsvakurudzi vanodavira kuti kupararira kwemadzitateguru edu ari kure omunhu, mahominini, kwakanga kwamiswa nokutonhora nokusanaya kwemvura. Asi mamiriro ezvinhu zvaaidziya, vakakwanisa kupararira kubva kuAfrica kuenda kuSpain, uye pakupedzisira vakapararira muEurope yose. Kutsvakurudza kwacho kwakatungamirirwa naDr Jordi Agusti weCatalan Institution for Research and Advanced Studies (ICREA). Kuti takava sei zvisikwa zvine mativi maviri, uye kuti takabva kupi, kwave kuri chikonzero chokukakavadzana. Imwe rondedzero inotaura kuti tateguru vedu vose vakanga vari gonye risina nhengo dzomuviri uye rakanga richingova negadziriro yetsingawo zvayo. Zvisinei, kutsvakurudza kwaDr Temereva kunotsigira imwe rondedzero. Anotaura kuti madzitateguru edu aiva nemakumbo - kana kuti zvigunwe - zvaishandiswa pakufamba uye kuunganidza zvokudya. Uye, anodaro, vaivawo negadziriro yetsinga dzakaoma kunzwisisa. Kuti...
Musayendisiti wokuRussia anoti tateguru vekare vevanhu vaiva nemapendekete. Dzakararama makore anodarika mamiriyoni 540 akapfuura uye dzaiashandisa sezvokudya. Zvingangodaro kuti vaivawo nehurongwa hwepfungwa hwakaoma kunzwisisa sezvatinoita nhasi. Kunopikisa imwe rondedzero inoti madzitateguru edu akanga akafanana zvikuru nehonye.
