Asuperhighway is put down in a field separating a population of snails. over time, they acquire mutations and become two different species. this is an example of speciation.

Alllopatric speciation.

Explanation:

This is the type of speciation in which organisms of the same species are separated from each other by geographical barrier (isolated) to the extent that the selective pressures in individual environment affected their gene flow.

Therefore , if the these organism mated when reunited,they will not be able to produce offspring.

It is also known as Geographical speciation. Therefore new species of organisms have emerged.

This is speciation.
