The process that may lead to speciation when a population adapts to its environment, and as an incidental consequence of that, becomes reproductively isolated from other populations is Natural selection.

Here's a step by step explanation:

1. Natural selection is a process where organisms that are better adapted to their environment tend to survive and produce more offspring. This is also known as survival of the fittest.

2. Over time, the traits that make these organisms more adapted to their environment increase in the population through inheritance.

3. As these traits become more common, the population evolves and may become so different that they become a separate species.

4. This new species is now reproductively isolated from the original population, meaning they can no longer interbreed. This is because they have become so genetically different due to the different traits that have been selected for in their specific environments.

5. This process of speciation through natural selection can occur when populations are separated by geographical barriers (allopatric speciation) or even when they live in the same area but use different resources or have different mating habits (sympatric speciation).

So, the correct answer is Natural selection.
