Hello!! Speciation will occur because there is a new species away from the others. Speciation means a new species will occur during evolution. I hope I helped!! Have a great day. :)
Answer:
The correct answer would be speciation.
Geographical isolation is one of the methods responsible for speciation.
Due to geographic isolation, the gene flow between two populations would not take place.
With time, the two populations would accumulate genetic variations, mutations, adaptations et cetera in such a great amount that they would not be able to interbreed with each other.
Thus, the two populations would evolve into two different species.
