Verified step by step guidance

1. Understand the Biological Species Concept: This concept defines a species as a group of individuals that can interbreed and produce fertile offspring. It emphasizes reproductive isolation from other groups.
2. Evaluate the statement about genetic similarity: While members of a species may share genetic similarities, the Biological Species Concept does not define species based on genetic similarity alone.
3. Consider the statement about interbreeding: According to the Biological Species Concept, the ability to interbreed and produce fertile offspring is a key criterion for defining a species.
4. Assess the statement about habitat: The ability to occupy the same habitat is not a defining feature of a species under the Biological Species Concept, as different species can share habitats.
5. Review the statement about physical characteristics: Members of a species do not always have identical physical characteristics, as there can be variation within a species. The Biological Species Concept focuses on reproductive capabilities.
