Wild male orangutans produce long calls composed of two hierarchical layers, wherein isochronous sub-pulses occur within isochronous pulses, indicating that recursive vocal combinatorics are not exclusive to language among hominids.

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

The morphology of the inner ear distinguishes major anthropoid clades and enables the proposal of various shared-derived features for apes as a whole, lesser apes, and great apes and humans.

A dedicated dataset for non-human apes improves pose estimation and tracking accuracy in apes.

The reconstitution of a functional envelope protein from an extinct hominid retrovirus reveals its receptor and an ancient host defense that may have led to the extinction of the virus.

Rapid evolution and gene conversion of a primate cell surface receptor family blocks recognition by pathogenic bacteria.

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.

Neural progenitors in humans and chimpanzee organoids show remarkably similar cellular and molecular parameters, but metaphase is longer during human mitosis.

Viruses drive adaptation at the scale of the whole proteome and not only in antiviral proteins in mammalian hosts.
