Body mass and encephalization in Pleistocene Homo

CB Ruff, E Trinkaus, TW Holliday - Nature, 1997 - nature.com
Many dramatic changes in morphology within the genus Homo have occurred over the past
2 million years or more, including large increases in absolute brain size and decreases in …

Morphological adaptation to climate in modern and fossil hominids

CB Ruff - American journal of physical anthropology, 1994 - Wiley Online Library
Hominids—both living and past—exhibit considerable variation in body size and shape. Both
theoretical considerations and empirical observations indicate that some of this variation …

Postcranial robusticity in Homo. I: Temporal trends and mechanical interpretation

CB Ruff, E Trinkaus, A Walker… - American journal of …, 1993 - Wiley Online Library
Temporal trends in postcranial robusticity within the genus Homo are explored by comparing
cross‐sectional diaphyseal and articular properties of the femur, and to a more limited …

Cross‐sectional geometry of Pecos Pueblo femora and tibiae—A biomechanical investigation: I. Method and general patterns of variation

CB Ruff, WC Hayes - American journal of physical anthropology, 1983 - Wiley Online Library
Variation in long bone cross‐sectional geometry can be given a more precise functional
interpretation using engineering beam theory. However, difficulties in measurement technique …

Biomechanical analyses of archaeological human skeletons

CB Ruff - Biological anthropology of the human skeleton, 2018 - Wiley Online Library
Biomechanics theory provides new ways to reconstruct behavior in past populations. Application
of biomechanical beam models to long bone diaphyses has proven to be a particularly …

Limb bone bilateral asymmetry: variability and commonality among modern humans

BM Auerbach, CB Ruff - Journal of human evolution, 2006 - Elsevier
Humans demonstrate species-wide bilateral asymmetry in long bone dimensions. Previous
studies have documented greater right-biases in upper limb bone dimensions—especially in …

Predicting femoral neck strength from bone mineral data: a structural approach

TJ Beck, CB Ruff, KE Warden, WW SCOTT Jr… - Investigative …, 1990 - journals.lww.com
An interactive computer program was developed to derive femoral neck geometry from raw
bone mineral image data for an estimate of hip strength using single plane engineering …

Postcranial robusticity in Homo. II: Humeral bilateral asymmetry and bone plasticity

E Trinkaus, SE Churchill, CB Ruff - American journal of physical …, 1994 - Wiley Online Library
The analysis of humeral asymmetry in Recent human skeletal samples and an extant tennis‐player
sample documents minimal asymmetry in bone length, little asymmetry in distal …

Articular and diaphyseal remodeling of the proximal femur with changes in body mass in adults

CB Ruff, WW Scott, AYC Liu - American journal of physical …, 1991 - Wiley Online Library
Proximal femoral dimensions were measured from radiographs of 80 living subjects whose
current body weight and body weight at initial skeletal maturity (18 years) could be …

Body size, body shape, and long bone strength in modern humans

CB Ruff - Journal of human evolution, 2000 - Elsevier
