Question

human beings do not have a chambered stomach like cows.why do we lack the process of rumination?explain

Answer 1

ruminants like cows and giraffes eat exclusively leaves, which are difácult to digest. The four chambered stomach provides a long digestive cycle, which they need to get enough energy. Humans and most other animals eat foods with more easily available energy, so a shorter digestive tract serves us just áne and there was no selective advantage in having a more complex digestive system.
