Quizplus · Accepted Answer

The shift to a diet rich in animal meat, facilitated by increased tool use, likely led to a smaller digestive system because meat is more nutrient-dense and easier to digest than the plant materials that would have made up a larger portion of the diet of earlier hominins. This dietary change also contributed to increased brain size, as the nutrients from meat are particularly beneficial for brain development.
