Animals that are Omnivorous

Omnivores are animals that feed on and digest both plant and animal matter. There are no specific groups that become omnivorous. For instance, bears evolved from the order Carnivora. At the same time, pigs came from the family of even-toed ungulates, which consists primarily of herbivores.

Animals with omnivorous diets tend to have specialized niches but exhibit higher food security in periods of scarcity.

The stomachs of herbivores have multiple chambers, and they have specialized digestive tracts.
