Hormones and Body Size *Evolution in Old World Monkeys
This research shows that similar adult body size can be attained despite differences in levels of growth regulatory hormones during development. Results also demonstrate that absolute hormone levels during growth do not necessarily relate to adult size, contrary to the findings of previous research …

The evolutionary transition from reptiles to mammals: analyses of body size reduction and separation of middle ear elements from the jaw
Body size generally decreased during synapsid evolution until the origin of mammals, and this decrease has often been linked to the evolution of mammal-like characteristics. Despite the importance of these patterns to our understanding of mammalian evolution, the particular evolutionary mechanisms …

Using multivariate calibration to evaluate hominin brain/body size relationships
… is that brains and bodies have both increased in size during the course of human evolution but the rate, timing, and evolutionary relationship of the two are still unclear. This study uses methods that increase the sample size of fossil hominins, provide more confidence in body mass estimates, and …

Body Size Histories in Cenozoic Reptiles From Global to Community Scales
Body size is a key ecological trait influencing trophic relationships, geographic distributions, and many other aspects of animal interactions with the environment. For poikilotherms, body size has a strong functional relationship to thermoregulation. This relationship means that body size …
