Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Munguva pfupi yapfuura, uchapupu hwokuti vanhu vose vakabva kune mumwe munhu hwakabva pakudzidza kufanana kwezvinhu zvipenyu. Somuenzaniso, masero ose anorarama anoshandisa zvinhu zvakafanana zvinonzi nucleotides uye amino acids. Kuvandudzwa kworuzivo rwezvinhu zvinogarwa nhaka kwakaratidza chinyorwa chokushanduka-shanduka chakasiiwa muzvinyorwa zvomuviri zvezvinhu zvipenyu: kufambidzana nenguva apo marudzi akaparadzana kupfurikidza nenguva yemamorekuru inogadzirwa neshanduko. Somuenzaniso, kuenzanisa urongwa hweDNA uku kwakaratidza kuti vanhu nemachimpanzi vane zvikamu 98 kubva muzana zvejenomu zvakafanana uye kuongorora nzvimbo shomanana dzavanosiyana kunobatsira kujekesa kuti tateguru vemarudzi aya vakamborarama rini.  Mubvunzo: Kufambira mberi kwezvinhu zvine chokuita nemasero emhuka kwakaratidzei?
