The production of a new species from two different species is known as speciation.
Factors responsible for it are:-
1)Natural selection:-Due some natural incidents ,there are genetic variations in new individuals,which led to evolving of new species.
2)Genetic drift:-Sudden alternation in gene frequency is called genetic drift
3)Survival advantage:-Due to camouflage some species enjoy the survival advantage.
4)Migration:-Migration of differnt species also led to evolvement of new species.

thanks a lot :-)
pls mark it as brainliest
Some other factors are chromosomal abberations ,Gene mutations and polymorphism
but in class 10th standard they are not so important.But thanks for your suggestion
Thanks for your comment

A species is a population of organisms which consist of similar individual which can breed together and can produce fertile offspring.
factors responsible for speciation :
- geographical isolation od a population caused by Various types of barriers, like mountains ranges, river, sea, etc. This geographical isolation leads to reproductive isolation due to which there is no flow of genes between separated group of population.
-Genetic drift causes by drastic changes in the frequencies of particular genes by chance alone.
-variation caused in individuals due to natural selection.
