Verified step by step guidance

1. The Biological Species Concept is a way to define species based on reproductive capabilities.
2. According to this concept, a species is defined as a group of organisms that can interbreed with one another.
3. Interbreeding must result in the production of fertile offspring, meaning the offspring can also reproduce.
4. This concept emphasizes reproductive isolation from other groups, which prevents gene flow between different species.
5. The Biological Species Concept is widely used because it focuses on genetic exchange and evolutionary processes.
