Here's the breakdown:
* Genus: A group of closely related species. Think of it like a family name. For example, the genus *Pan* includes chimpanzees, bonobos, and gorillas.
* Species: A group of organisms that can reproduce with each other and produce fertile offspring. This is the most specific level of classification.
The key is that a genus can contain multiple species.
For example:
* Genus *Pan*
* Species *Pan troglodytes* (Chimpanzee)
* Species *Pan paniscus* (Bonobo)
* Species *Pan gorilla* (Gorilla)
All three species share a common ancestor and are closely related, but they are distinct enough to be considered separate species.
So, while two animals in the same genus are definitely related, they might not be the same species!
