Pfupisa nyaya yacho:  Vanhu vemazuva ano vakapomerwa mhosva yokuuraya vanhu vekare kupfurikidza nokukwikwidzana navo, kuberekana navo uye kunyange kuvauraya chose chose. Asi kutsvakurudza kutsva kunoratidza kuti zvirwere zvinotapuriranwa zvakatakurwa namadzitateguru edu azvino uno pavakabuda muAfrica ndizvo zvakapedza upenyu hwavo. Masayendisiti ari kudzidza uchapupu hwazvino uno hwemavara okugara nhaka, hwezvisaririra uye hwezvokuchera matongo anotaura kuti vanhu vokuNeanderthal vairwara nezvirwere zvakasiyana-siyana zvichiri kutitambudza nhasi. Dzorera pasi kuti uone vhidhiyo. Vanhu vokuNeanderthal, kufanana nokuvakwazve kuri kuratidzwa pamusoro apa paNatural History Museum muLondon, vangave vakafa nezvirwere zvinotapukira zvakaendeswa kuEurope nevanhu vemazuva ano pavakabuda muAfrica. Vakawana uchapupu hunoratidza kuti hama dzedu dzomunguva dzisati dzavapo dzaigona kunge dzaiva nezvirwere zvakadai setibhii, typhoid, chikosoro, encephalitis uye dzihwa. Asi nyanzvi dzezvinhu zvipenyu zvevanhu dzeCambridge University neOxford Brookes University dzinoti zvirwere zvitsva zvinotakurwa nevanhu vemazuva ano zvingave zvakatungamirira kukuparara kwavaNeanderthal. Pave nemakore anenge 30 000 kubvira apo madzitateguru evanhu vemazuva ano anofungidzirwa kuva akatsakatisa vanhu vekare veNeanderthal. Asi marudzi akaparara angave ari kutsiva kwatiri kubva kunze kweguva kupfurikidza nokuita kuti tive vanotambura zvikuru nezvirwere zvinogona kuuraya zvakadai sekenza uye chirwere cheshuga. Vanhu vokuNeanderthal nevanhu vemazuva ano vanofungidzirwa kuti vakararama pamwe chete kwezviuru zvemakore uye vakabatanidzwa, zvichireva kuti vanhu vokuEurope zvino vane inenge 2 muzana yeDNA yevanhu vokuNeanderthal. Aya majini 'akagara nhaka' akabatanidzwa nengozi yakawedzerwa yekenza uye chirwere cheshuga nezvidzidzo zvitsva zvinotarisa nhoroondo yedu yokushanduka-shanduka. Zvisinei, mamwe majini atakagara nhaka angadai akavandudzawo kudzivirira kwedu zvimwe zvirwere. Masayendisiti akawana kuti rutivi rwesangano redu reHLA, runobetsera masero machena eropa kuziva nokuparadza zvinhu zvisiri zvomuviri, rwaigona kuva rwakabva kuNeanderthals. Vamwe vatsvakurudzi vakataura kuti vanhu vari kunze kweAfrica vanokurumidza kubatwa nechirwere cheshuga chinonzi Type 2 nokuti vakaberekwa nevanhu vekare....
Nyanzvi dzezvevanhu dzinotaura kuti vanhu vekare vaiva nezvirwere zvakawanda zvemazuva ano. Ongororo yeDNA yakaratidza kuti vakanga vasingabatwi nezvirwere zvinozivikanwa navose. Asi vanodavira kuti vanhu vemazuva ano vakaunza utachiona hutsva hunotapukira hwakadai seHeliocbacter pylori kubva kuAfrica uye vakabata vanhu vokuNeanderthal. Izvi zvinoratidza kuti zvirwere zvinotapukira ndezvekare zvikuru kupfuura zvaifungidzirwa kare.
