Our diet has a direct impact on our quality of life, and this fact is not new. Throughout the evolution of our species, food availability and our diet have been influential factors. The Hominin River has provided insights into the dietary habits of our predecessors and how it affected their brain size and ability to walk on two legs. The transition from herbivores to omnivores, as well as learning how to cook food, caused a reduction in teeth size and gut size. Despite not documenting their meals or counting calories, our ancient hominin ancestors were keen on experimenting with what they ate. Their primary concern was avoiding predators, so we rely on archaeological findings to understand their diet. Evolution Talk is also a book!
