Verified step by step guidance

Understand the concept of speciation, which is the process by which populations evolve to become distinct species.

Identify the types of speciation: Allopatric, Sympatric, Metapatric, and Geopatric.

Recognize that allopatric speciation occurs when a geographic barrier, such as a mountain range or river, physically separates a population into two or more groups.

Consider how geographic isolation in allopatric speciation prevents gene flow between the separated groups, leading to evolutionary divergence.

Compare allopatric speciation with other types, noting that sympatric speciation occurs without physical barriers, while metapatric and geopatric are less commonly used terms in speciation discussions.
