Here's why:
* Reproduction: The ability to reproduce is a key characteristic of life, and species are defined by their ability to interbreed and create fertile offspring.
* Shared Gene Pool: Members of the same species share a common gene pool, meaning they have similar genetic makeup. This allows them to produce offspring that are also capable of reproduction.
* Evolutionary Units: Species are considered the fundamental units of evolution. They evolve over time through natural selection, adapting to their environment.
While individuals within a species can vary, they are generally considered to be part of the same species because they can interbreed and produce viable offspring.
