Abstract

We conducted a meta-analysis of 45 studies reporting basal metabolic rate (BMR) data for Homo sapiens and Pan troglodytes to determine the effects of sex, age, and latitude (a proxy for climate, in humans only). BMR was normalized for body size using fat-free mass in humans and body mass in chimpanzees. We found no effect of sex in either species and no age effect in chimpanzees. In humans, juveniles differed significantly from adults (ANCOVA: P < 0.001), and senescent adults differed significantly from adults younger than 50 years (P < 0.001). Europeans differed significantly from tropical populations (P < 0.001). On the basis of these observations, we derived new equations describing the relationship between BMR and body size, and used them to predict total daily energy expenditure (TEE) in four early hominin species. Our predictions concur with previous TEE estimates (i.e. Leonard and Robertson: Am J Phys Anthropol 102 (1997) 265-281), and support the conclusion that TEE increased greatly with H. erectus. Our results show that intraspecific variation in BMR does not affect TEE estimates for interspecific comparisons. Comparisons of more closely related groups such as humans and Neandertals, however, may benefit from consideration of this variation.

  • RMR among adult orangutans in our sample was an average of 23% lower (range, 7-35% lower) than the basal rate of metabolism predicted for their body mass, and significantly lower than BMR reported for humans and chimpanzees (Student t test, P < 0.05 for both comparisons).

    “RMR among adult orangutans in our sample was an average of 23% lower (range, 7–35% lower) than the basal rate of metabolism predicted for their body mass, and significantly lower than BMR reported for humans (20) and chimpanzees (13) (Student t test, P < 0.05 for both comparisons; Fig. 3).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
