- Biomechanics of running indicates endothermy in bipedal dinosaursHerman Pontzer
Department of Anthropology, Washington University, St Louis, Missouri, United States of America
PLoS ONE 4:e7783. 2009..For example, some studies have suggested that, because large dinosaurs may have been homeothermic due to their size alone and could have had heat loss problems, ectothermy would be a more plausible metabolic strategy for such animals...
- Predicting the energy cost of terrestrial locomotion: a test of the LiMb model in humans and quadrupedsHerman Pontzer
Washington University, 119 McMillan Hall, St Louis, MO 63130, USA
J Exp Biol 210:484-94. 2007..Results suggest the LiMb model reliably links locomotor anatomy to force production and locomotor cost. Further, these data support the idea that limb length may underlie the scaling of locomotor cost for terrestrial animals...

Department of Anthropology, University of Arizona, 1009 E South Campus Drive, Tucson, AZ 85721, USA
J Hum Evol 54:112-7. 2008..Despite the many attempts to discern limb-joint kinematics from Laetoli stride lengths, our study concludes that stride lengths alone do not resolve the debate over early hominin locomotor postures...
- Understanding hind limb weight support in chimpanzees with implications for the evolution of primate locomotionDavid A Raichlen
Department of Anthropology, University of Arizona, Tucson, AZ 85721, USA
Am J Phys Anthropol 138:395-402. 2009..The latter hypothesis raises the intriguing possibility that primate weight support patterns actually evolved as byproducts of other traits, or spandrels, rather than as adaptations to increase forelimb mobility...
- Chimpanzee locomotor energetics and the origin of human bipedalismMichael D Sockol
Department of Anthropology, University of California, Davis, CA 95616, USA
Proc Natl Acad Sci U S A 104:12265-9. 2007..Analyses of these features in early fossil hominins, coupled with analyses of bipedal walking in chimpanzees, indicate that bipedalism in early, ape-like hominins could indeed have been less costly than quadrupedal knucklewalking...

Department of Anthropology, Hunter College 695 Park Avenue, New York, New York 10065, USA
Nature 533:390-2. 2016..Humans also had the greatest body fat percentage. An increased metabolic rate, along with changes in energy allocation, was crucial in the evolution of human brain size and life history. ..

Harvard University, Department of Anthropology, 11 Divinity Avenue, Cambridge, MA 02138, USA
J Exp Biol 208:1513-24. 2005..Results suggest the model is useful for predicting COL from anatomical and kinematic variables, and may be useful in intra- and inter-specific studies of locomotor anatomy and performance...

Am J Phys Anthropol 143:52-61. 2010..The differences in gait between mature and immature walkers, and hence the differences in femoral shape, are likely partially a product of a minimal bicondylar angle and relatively broad body in young children...
