File:Estimated proportions of major organs in a modern Western human vs ape-likeness expectation.webp

English: "Proportions of major organs in a hypothetical 65 kg modern Western human using data from Table 1. “Expected” represents the ratio of organ masses expected if humans had proportions in line with other great apes. “Actual” represents an estimation of the ratios in a typical modern Western human." "Fig. 2 shows the relationship between organ sizes in a hypothetical 65 kg human with ape-like organ sizes (expected) and the actual proportions in modern western humans (actual). While total gut reduction is impressive (a reduction of over 41%), the reduction is not consistent across subcomponents. Small intestine proportion actually increases, from approximately. 4 kg to. 62 kg in modern humans, an increase of 58%. The subcomponent which accounts for the largest share of the reduction is the colon. With a predicted ape-like value of 0.85 kg, a typical human instead has an estimated mass of. 22 kg, a reduction of 74%—the largest reduction of any of the gut subcomponents and any of the other major organs (Table 2)."
