New species are produced as a result of :
(a) Mutation giving rise to new genetic variations.
(b) Genetic recombination during sexual reproduction provides wider variability for natural selection to operate.
(c) Natural selection of variants better adapted to the existing environment.
(d) Genetic drift-random increase in the number of variants not having any selective advantage due to chance factor.
(e) Reproductive isolation of populations with different characters due to geographical or behavioral factors.
