- kramavikas siddhatan ki mukhy batean is prakar hai-
- vishesh prakar ki kee prajatiyoan ke paudhe pahale ek hi jaise hote the, par sansar mean alag alag jagah ki bhugaulik prasthitiyoan ke karan unaki rachana mean parivartan hota gaya jisase us ek jati ki kee prajatiyaan ban gee.
- paudhoan ki tarah jivoan ka bhi yahi hal hai, manushy ke poorvaj kisi samay bandar hua karate the, par kuchh bandar alag se vishesh tarah se rahane lage aur dhire–dhire zarooratoan ke karan unaka vikas hota gaya aur vo manushy ban ge. is tarah se jivoan mean vatavaran aur paristhitiyoan ke anusar ya anukoolakary karane ke lie 'kramik parivartan' tatha 'isake phalasvaroop nee jati ke jivoan ki utpatti' ko kram–vikas ya vikasavad (Evolution) kahate haian.
