Natural selection.
Genetic engineering.
Geographic isolation.
Reproductive isolation.
Ecological competition.
Movement in and out of populations.
There're A LOT more reasons.
Some animals mutate creating adaptations that make them more successful than other animals. through these adaptations natural selection weeds out the least adaptive to change and thus you have some animals more healthier, stronger and smarter than others.

The oxymoron in Animal Farm is the phrase "All animals are equal, but some animals are more equal than others."
