The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

Biological Reviews, Volume 101, Issue 3, Page 1235-1254, June 2026.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Beyond Body Mass, Beyond Adulthood: The Ontogeny of Sexual Size Monomorphism

American Journal of Biological Anthropology, Volume 190, Issue 1, May 2026.
ABSTRACT Objectives Contest competition for mates and female reproductive energetics influence body size and sexual dimorphism across many primates; nevertheless, some monomorphic species defy these patterns. These deviations may reflect biological anthropology's focus on body mass and adult size as defining features of sexual dimorphism.

No Evidence of Reactive Avoidance of Baboons (Papio ursinus and Papio anubis) to the Presence of Predators

Ecology and Evolution, Volume 16, Issue 5, May 2026.
In this study, we took advantage of the largest camera trap‐based monitoring project in Africa, Snapshot Safari and analyzed 10,000 camera trap detections from three sites in South Africa and one site in Tanzania to test whether baboons exhibit species‐specific reactive avoidance in response to the presence of predators. ABSTRACT Predators exert strong
