Darwinists maintain that living things evolve as a result of chance mutations and that blind and unconscious mutations gave rise to all the glorious variety of life we see on the Earth today.
Wafuasi wa Darwin wanashikilia kuwa viumbe hai wanabadilika kutokana na mabadiliko ya bahati nasibu na mabadiliko hayo yasiyo na utambuzi ndiyo yaliyozalisha viumbe mbalimbali vizuri tunavyoviona hapa duniani hivi leo.
