How does the fact that humans are omnivores influence our anatomy and behavior?

Based on anatomy, humans share anatomical features with those of omnivores (e.g. pigs, mice, rats, rodents, raccoons, etc.). The omnivores lack specialized storage and digestive sacs, such as fermenting vats. Vats are enlarged chambers where food could stay for microbes to “digest” it.
