Different dogs look incredibly different - but that doesn't mean they are necessarily more diverse.

**************

To learn more about this topic, start your googling with these keywords:

phenotypic diversity - the range of different observable traits in a certain organism - for example, size, color, strength, and friendliness.

genetic diversity - the variation in the genetic information within and among individuals of a population or species

artificial selection (or selective breeding) - a process used by humans to develop new organisms with desirable characteristics
