Darvinova teorija evolucije
Opisao je kako se dešavaju postepene promene vrsta kroz vreme i kako nastaje različitost živog sveta
Uzrok postepenih promena je borba za opstanak
Sve jedinke jedne vrste međusobno se razlikuju, svaki organizam je jedinstven i drugačiji
Primer braća i sestre od istih roditelja
Čak i jedinke koje nam izgledaju isto nisu isti svaki je jedinstven
Ove jedinke ulaze u borbu za opstanak-stanište, hranu, partnera za razmnožavanje
Preživljavaju one koje su najbrže, najspretnije, najotpornije

Darvinizam
sve vrste imaju zajedničkog pretka
-prirodna selekcija utiče na
stvaranje novih vrsta
-vrste podležu prirodnoj selekciji

Savremena teorija evolucije
Temelji se na Darvinovoj teoriji i dodatno je objašnjava
U populaciji postoji fenotipska varijabilnost koja potiče od razlika u naslednim osobinama - genetička varijabilnost ili od uticaja sredine
Genetička varijabilnost je postojanje različitih varijanti gena- genskih alela za neku naslenu osobinu
