Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: 1900 yakaratidza kunonzi kuwanikwazve kwaMendel: Hugo de Vries, Carl Correns, naErich von Tschermak vakazvimiririra vakasvika pamitemo yaMendel (iyo yakanga isiripo mubasa raMendel). Nokukurumidza pashure pacho, nyanzvi dzamasero dzakaronga kuti makromosome ndiwo aiva zvinhu zvinogarwa nhaka. Pakati pa1910 na1915, Thomas Hunt Morgan ne"Drosophilists" mufly lab yake vakaumba pfungwa idzi mbiri - dzose dziri mbiri dzinopokanidzwa - mu"Mendelian-chromosome theory" yenhaka. Vakaverenga huwandu hwechinhu chinonzi genetic linkage ndokubva vati majini anogara pama chromosomes kunge marozari ari patambo; vakafungidzira kupindana kuti vatsanangure chinonzi linkage ndokubva vagadzira mepu dzemajini eDrosophila melanogaster, iyo yakazova modhi inoshandiswa zvakanyanya. Hugo de Vries akaedza kubatanidza majini matsva nekushanduka-shanduka; achivakira pabasa rake rekugara nhaka uye kusanganisa, akataura dzidziso ye mutationism, iyo yakagamuchirwa zvakanyanya mukutanga kwezana ramakore rechi20. Lamarckism, kana kuti rondedzero yokugara nhaka yezvinhu zvakawanwa yakanga iinewo vateveri vakawanda. Darwinism yaionekwa seisingawirirani nezvimiro zvinogara zvichichinja zvinodzidzwa nenyanzvi dzemaumbirwo ezvinhu zvipenyu, izvo zvaiita sokuti zvinongogarwa nhaka zvishoma. Muma1920 nema1930- zvichitevera kugamuchirwa kwedzidziso yeMendelian-chromosome theory- kubuda kwedzidzo yepopulation genetics, nebasa raR.A. Fisher, J.B.S. Haldane naSewall Wright, vakabatanidza pfungwa yekushanduka-shanduka nekusarudzwa kwechisikigo nemaMendelian genetics, vachigadzira synthesis yemazuva ano. Nhaka yehunhu hwakagamuchirwa yakarambwa, nepo mutationism yakapa nzira sezvo dzidziso dzemajini dzakura. Muhafu yechipiri yezana ramakore pfungwa dzezvinhu zvemajini zvevanhu dzakatanga kushandiswa murango mutsva wezvinhu zvemajini zvemaitiro, sociobiology, uye, zvikurukuru muvanhu, psychology yekushanduka-shanduka. Muma1960 W.D. Hamilton nevamwe vakagadzira dzidziso yemitambo kuti vatsanangure kuzvipira kubva pakuona kwekushanduka-shanduka kuburikidza nekusarudzwa kwehama. Mavambo angangodaro ezvisikwa zvakakwirira kupfurikidza neendosymbiosis, uye anosiyanisa...  Mubvunzo: Chii chinopfuudzwa kubva kumubereki kuenda kumwana?
