Hey there!
SPECIATION:
It is the process of formation of new species from preexisting species.
★ Factors responsible for speciation:
1. Geographical barrier
2. Natural selection
3.Genetic driftLarge mutation
GEOGRAPHICAL BARRIER:
Geographical isolation is isolation of a species or a group of individuals from others by the means of some physical (geographical) barrier like river, mountain,big glacier etc.
As the result of geographic isolation, the two species are reproductively isolated. Geographical isolation results in evolution of new species.
NATURAL SELECTION:
It is the process by which nature selects the individual which can survive in a particular kind of environment with best possible traits. The nature selects those individuals which have variations which makes them more fit than others for the given environment.
Selection performed by nature, of the best suited varieties (having favourable variations) to survive and destruction of the less suited varieties through exposure to environmental stresses results in the formation new species.
GENETIC DRIFT:
Genetic drift may be defined as the sudden change in the frequency of the alleles of a gene in a given population. The random genetic drift may be an important factor in the formation of new species.
Cheers!

THE EVOLUTION OF NEW SPECIES FROM THE EXISTING SPECIES IS CALLED SPECIATION.
ITS FACTORS ARE
1. GEOGRAPHICAL ISOLATION
2.GENITIC DRIFT
3.NATURAL SELECTION
