Zvadaro pindura mubvunzo wacho uchishandisa mutauro mumwe chete: Zvadaro, uchapupu hwekuti vanhu vakabva kune imwe nyika hwakabva pakudzidza zvakafanana zvinoitwa zvinhu zvipenyu. Semuenzaniso, masero ese anorarama anoshandisa zvinhu zvakafanana zvinoumba nucleotides uye amino acids. Kuvandudzwa kwedzinza remamolecular kwakafumura nhoroondo yekushanduka-shanduka yakasiyiwa mumagenesimu emhuka: kufambidzana nenguva yakasiyana-siyana kwemarudzi kuburikidza nekushanduka-shanduka kwemamolecular clock. Semuenzaniso, kuenzanisa uku kweDNA sequence kwakaratidza kuti vanhu nemachimpanze vane 98% yemagenesimu akafanana uye kuongorora nzvimbo shoma dzavanosiyana kunobatsira kujekesa kuti tateguru wemarudzi aya akamborarama riini. Mubvunzo: Kuvandudzwa kwedzinza remamolecular kwakafumura chii?
chinyorwa chokushanduka-shanduka chakasiyiwa mugenomu rezvinhu zvipenyu
