Factors that would lead to rise of new species are:
(i) Migration
(ii) Natural selection
(iii) Geographical isolation
(iv) Mutation.
Speciation can happen if two groups of the same species are somehow prevented from interbreeding for several generations. This can happen because of geographical segregation or because of some genetic changes.
Natural selection, genetic drift and acquisition of traits during the life time of an individual
can give rise to new species.
