Answer:
The process of speciation leads to the formation of new species by preventing the flow of genes between the populations.
Speciation is a natural phenomenon by which new species are formed with the help of other processes such as natural selection, genetic drift, mutations, geographic isolation, reproductive isolation et cetera.
In geographic or reproductive isolation, the flow of genetic material is prevented among the populations.
With time, due to the accumulation of genetic changes, the populations can no longer interbreed and thus, results in the production of new species.
