Nei kune varume?

Zvikonzero zvekuvapo kwevanhu kwenguva refu zvakanetsa pfungwa dzevasayendisiti. Kuita zvepabonde kunobata zvisina kukodzera uye kunodhura, asi akawanda emarudzi akawanda anosarudza nzira iyi kuitira kuchengetedza mazamu avo. Izvi hazvina musoro. Saka nei pane varume? Vatsvakurudzi vanobva kuYunivhesiti yeEngland Anglia vanotenda kuti, zvichida, nhamba iyi yakagumburwa. Vanoratidza kuti simba rekushanduka-shanduka, rinozivikanwa sekusarudza zvepabonde, rinotora basa rinokosha mukuvandudza hutano hwevanhu uye kuchengetedza mhuka kubva pakuparara.

Ongororo itsva

Mune chidzidzo chakabudiswa mupepanhau Nature, subspecies yeTrbolium nyuchi dzakasarudzwa kuti dzicherechere kuti sei mazhinji ezvisikwa zvipenyu anosarudza kurara kwekubata. Mune hutachiona hwema laboratori, vatsvakurudzi vakaongorora zvizvarwa makumi mashanu zvezvinyuchi zvemakore gumi uye vakaona migumisiro yekusarudza zvepabonde. Maererano nenheyo yaCharles Darwin, kusarudzwa kwepabonde ndiyo nzira iyo varume vanorwisana nayo mukana wekubereka, uye vakadzi vanosarudza avo vanogadzirira kubereka.

Scientific point of view

"Munenge mhando dzose dzemarudzi akawanda pasi pano dzinobereka kuburikidza nekuita zvepabonde, asi huripo hahuri nyore kuitsanangura, nokuti rudzi urwu runounza mitoro inorema uye inoda kushandisa mari yakawanda simba." Uyezve, zviri pachena kuti hafu yevana vako-vanasikana vachave Zvechokwadi, ivai nevana. "Nei shiri dzinoshandisa nguva yavo nesimba pamusoro pevanakomana vavowo?" "Anodaro mumwe muongorori anotsvaga, Purofesa Matt Gage weEUA School, mumashoko.

Basa rekudzidza

"Taida kunzwisisa kuti kusarudzwa kweDarwinian kwakabvumira sei kuti chiitiko ichi chipararire, uye nei chibereko chekubereka chiri kuparadza, nokuti nzira iyo vanhu vose vanoberekera vana vasina kuita zvepabonde, sezvinoitwa neese asexual populations, inonyanya kubudirira," inotaura Muchidzidzo.

Mhinduro dzekuedza

Masayendisiti akawana kuti apo makwikwi acho akabviswa, uye mhuka dzebhinzi dzikaramba dzichigadzikana chete mumhuri miviri, hutano hwevanhu huri kuwedzera zvakanyanya. Asiwo, vana vakagamuchira mumamiriro ekukwikwidzana kwakanyanya, apo paiva nevarume gumi kune varume 90, vakanga vasingagoni kurwisana nehosha uye kuparara.

"Kuti uve munhu akakurudzika wepikwikwi nekukwikwidzana, munhu anofanira kunge akanaka pane zvimwe zvinhu, kuitira kuti kusarudza zvepabonde chinhu chinokosha uye chinoshanda chekuchengetedza nekuvandudza utano hwezvemagariro evanhu," Gage anoti. Ichokwadi kuti hupombwe hunoramba huripo sehukuru hwekuberekwa, sezvo hunobvumira kusarudzwa kwepabonde kupa huno hunokosha hwemagetsi. "

Chidzidzo chacho chinoratidza kuti chiitiko chakadai sekusarudza zvepabonde chinotora basa rinokosha pakucherechedza kunze kwekukuvadza kuchinja kwemashoko, nokuti kukwikwidzana kunoreva mikana shomanana yekuti mukadzi ave nemurume nemukadzi ane chimiro chakashata.
