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 mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Social Drivers of Vocal Flexibility in Female Baboons

Ethology, Volume 132, Issue 6, Page 390-398, June 2026.
Female olive baboons selectively grunt when encountering females with dependent offspring. Grunting likelihood depends on rank differences and the strength of their social bond. This study adds to the evidence that nonhuman primates have evolved to use structurally‐inflexible vocalisations in population and context‐flexible ways.

The population status and maize crop-raiding activities of Papio anubis and Chlorocebus pygerythrus in the Abala Abaya forest, located in southern Ethiopia

Discover Applied Sciences
Species and subspecies of primates occur in different parts of Ethiopia, and some of them are successful crop raiders. We conducted a study on the population status and maize crop-raiding activities of Anubis baboons (Papio anubis) and Vervet monkeys ...

Validation of Immunoassays for Total Thyroxine and Free Thyroxine and Age and Sex‐Related Variation in Thyroid Hormone Serum Concentrations in Orangutans (Pongo sp.)

Journal of Medical Primatology, Volume 55, Issue 3, June 2026.
ABSTRACT Background Thyroid disease is reported in orangutans, but to properly diagnose and manage these disorders, reference intervals for circulating thyroid hormones are needed. Methods Commercial immunoassay kits for total thyroxine (TT4) and free thyroxine (FT4) were validated for use in orangutans (Pongo spp.).

Occurrence of gastrointestinal (GI) parasites in captive Olive Baboon and Common Langur in Bangladesh

Animal Diseases, 2022
Non-human primates (NHPs) serve as necessary reservoir hosts of parasites that create diseases to human. A close interaction between human and NHP can make a pathway for transmission of zoonotic diseases.

Monkey Meltdowns: Do Tantrums Influence Maternal Investment in Bearded Capuchin Monkeys?

Developmental Psychobiology, Volume 68, Issue 3, May 2026.
ABSTRACT Tantrums are widely discussed in human development literature and are typically defined as displays of frustration or anger. In behavioral ecology, they are hypothesized to function as a strategy for securing greater maternal investment. Infant primates often exhibit tantrums when their attempts to obtain maternal care are rejected.
