New four-million-year-old hominid species from Kanapoi and Allia Bay, Kenya
Nine hominid dental, cranial and postcranial specimens from Kanapoi, Kenya, and 12 specimens from Allia Bay, Kenya, are described here as a new species of Australopithecus dating from between aboutExpand

The primate semicircular canal system and locomotion
The semicircular canal system of vertebrates helps coordinate body movements, including stabilization of gaze during locomotion. Quantitative phylogenetically informed analysis of the radius ofExpand

Growth processes in teeth distinguish modern humans from Homo erectus and earlier hominins
A modern human-like sequence of dental development, as a proxy for the pace of life history, is regarded as one of the diagnostic hallmarks of our own genus Homo. Brain size, age at firstExpand

Postcranial robusticity in Homo. I: Temporal trends and mechanical interpretation.
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 extent, the humerus,Expand

Dental microwear texture analysis shows within-species diet variability in fossil hominins
Reconstructing the diets of extinct hominins is essential to understanding the paleobiology and evolutionary history of our lineage. Dental microwear, the study of microscopic tooth-wear resultingExpand

Dental microwear texture analysis: technical considerations.
Dental microwear analysis is commonly used to infer aspects of diet in extinct primates. Conventional methods of microwear analysis have usually been limited to two-dimensional imaging studies usingExpand

New specimens and confirmation of an early age for Australopithecus anamensis
The discovery of Australopithecus anamensis fossils from strata lying between tephra dated at 4.17 and 4.12 million years ago, and from slightly higher strata not well constrained in age by overlyingExpand

Early Homo erectus skeleton from west Lake Turkana, Kenya
The most complete early hominid skeleton ever found was discovered at Nariokotome III, west Lake Turkana, Kenya, and excavated in situ in sediments dated close to 1.6 Myr. The specimen, KNM-WT 15000,Expand

Postcranial robusticity in Homo. III: Ontogeny.
The influence of developmental factors on long-bone cross-sectional geometry and articular size in modern humans is investigated using two approaches: (1) an analysis of the effects of increasedExpand

2.5-Myr Australopithecus boisei from west of Lake Turkana, Kenya
Specimens of Australopithecus boisei have been found in 2.5-Myr-old sediments west of Lake Turkana, Kenya. The primitive morphology of these early A. boisei suggests that robust and hyper-robustExpand
