Expensive tissue hypothesis - Wikipedia

WebThe “ expensive tissue hypothesis ” proposes that maintaining a brain is metabolically expensive and that, in order to meet the energy requirements of a larger brain, our digestive system became smaller and shorter, making it more suited for higher-quality, nutrient-dense food such as meat (Aiello and Wheeler 1995). The expensive tissue hypothesis (ETH) relates brain and gut size in evolution (specifically in human evolution). It suggests that in order for an organism to evolve a large brain without a significant increase in basal metabolic rate (as seen in humans), the organism must use less energy on other expensive tissues; … See more The original paper introducing the ETH was written by Leslie Aiello and Peter Wheeler.
