Speciation is the process of creating new species out of existing species. It occurs due to genetic, geographic, or reproductive forms of population division within a species which eventually drifts apart with the passage of time due to Darwinian pressures. The pressure may be one of the four kinds: mutations, natural selection, genetic drift, or environmental.

Allopatric speciation: This happens when the population gets divided by some physical barrier, like a mountain or a river. It leads to genetic divergence eventually making different species.

Sympatric speciation No geographical isolation, usually owing to behavioral, ecological, or genetic conditions that can prevent interbreeding in the same area.

Peripatric and parapatric speciation: When adjacent populations are not vicariously separated but because of different environmental conditions or niches lead to speciation. The easiest process of evolution is speciation. It explains why there is such biodiversity on Earth. It gives the explanation of how species adapt to new environments, and why the different species are so frequently well-suited to definite habitats. The theory of natural selection by Charles Darwin helps to explain, through speciation, the evolution of species adaptation.
