=>Factors that could lead to the rise of a new species are as follow :

(i) Natural selection.


(ii) Process of genetic drift


(iii) Genetic Mutation


(iv) Geographical isolation.


(v) Environmental factors on the isolated populations.


(vi) Reproductive isolation for a long time.


(vii) Quantum of genetic variant inherited from one.




>Factors that affect the process of speciation are:
•Geographical isolation –
•Genetic drift –
•Natural selection –
