Biological+Species+Concept

Biological Species Concept The AP Biology book defines the **biological species concep**t as "a population or group of populations whose members have the potential to interbreed in nature and produce viable, fertile offspring, but are unable to produce viable, fertile offspring with members of other populations (1).

In other words, if a fertile male giraffe and a fertile female giraffe got together, they would have (most likely) fertile baby giraffes. However, if a fertile male giraffe and a fertile lion got together (unlikely, but for the sake of the argument, possible) they would not have fertile baby gions or liraffes.
