It is possible that God made genetic changes to humanity to better enable people to survive in different ecologies, such as the darker skin of Africans being better equipped genetically to survive the excessive heat in Africa. According to this view, God confused the languages, causing humanity to segregate linguistically, and then created genetic racial differences based on where each racial group would eventually settle.
Inaweza wezekana kuwa Mungu alifanya ubadilisho kidogo ili awawezeshe wanadamu kuishi katika anga mbalimbali, kama vile ngozi nyeusi kwa Afrika, kwa chembe chembe za damu ziwawezeshe kukaa mahali kuna joto nyingi sana Afrika. Kulingana na mtazamo huu, Mungu alichanganyisha lugha, kuwafanya wanadamu kutawanyika kilugha, na hapo akaumba chembe chembe za damu tofauti kulingana ni wapi kikundi fulani kitaishi.
