Answer 1

is those the answer choices?

Answer 2

Allopatric speciation

Step-by-step explanation:

Allopatric speciation refers to the geographical isolation of two populations of a species. These isolated populations accumulate variations in time and become reproductively isolated from each other. Hence, the presence of any physical barriers such as rivers, mountains, etc. does not allow the organisms from the same species to interbreed and leads to allopatric speciation.
