What is the first step in allopatric speciation?
Understand the Problem
The question is asking about the initial process that occurs in allopatric speciation. Allopatric speciation involves the formation of new species in populations that are geographically isolated from one another. Understanding the first step in this process helps clarify how species diverge over time due to reproductive isolation caused by physical barriers.
