The evolution 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 . These two forces can exert their effects in a time perspective (and spatial).
The mageuzi 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 . Haya majeshi mawili linaweza kutumia athari zao katika mtazamo wa muda (na vidudu).
