A new high-resolution approach to probing tooth chemistry shows real potential to uncover changing rainfall patterns and environmental conditions during human prehistory.

The most recent common ancestor of humans, chimpanzees, and bonobos possessed a foot adapted to terrestrial quadrupedalism and climbing.

The human-like joint proportions of Australopithecus afarensis evolved independently, making 'Lucy' and her kind the earliest known evolutionary experiment in obligate bipedalism.

Loss of Inverted Formin-2 impairs intracellular trafficking and trophoblast invasion, resulting in maternal hypertension and intrauterine growth restriction, which represents a novel model of impaired placental invasion that encompasses critical aspects of the great obstetrical syndromes.

An analysis of innate immunity reveals why dengue viruses do not reach high titers in primate laboratory models, even though they emerged through zoonotic transmission from primate reservoirs.

Stdpopsim, a framework for generating realistic chromosome-scale simulations, is expanded to facilitate simulations for non-model species, resulting in insights into how such simulations should be designed.

The stdpopsim library, a community-driven open source project, is presented which provides easy access to a standard catalog of published simulation models for population genetics aimed at field-wide standardization.

Travel has a major influence on tool use in wild chimpanzees, suggesting that tool use reduced travel costs during hominid evolution.

Elephants escaped enhanced cancer susceptibility by evolving more master tumor suppressor genes.
