Theevolution Organic can be defined as the change, the transformation of living species over time. It can be expressed through the reproduction of organisms within a species and involves “descent with modification” in the words of Darwin. This is a complex process subject to different evolutionary forces of two main types: la variation (such as mutations and genetic drift) and selection.
Themageuzi Organic unaweza kuelezwa kama mabadiliko, mabadiliko ya aina ya kuishi baada ya muda. Inaweza kuwa walionyesha kwa njia ya uzazi wa viumbe ndani ya mti na inahusisha “asili na muundo” katika maneno ya Darwin. Hii ni tata mchakato wa chini ya vikosi tofauti ya mabadiliko ya aina mbili kuu: la tofauti (kama vile mutations na maumbile drift) na uteuzi.
