Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1463-1478, June 2026.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Auditory neuroscience: the salience of looming sounds [PDF]

open access: yes, 2003
Sounds that move towards us have a greater biological salience than those that move away. Recent studies in human and non-human primates demonstrate a perceptual and behavioural priority for such looming sounds that is also reflected in an asymmetric ...

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

open access: yesJournal 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.).

Molecular Detection of Toxoplasma gondii in Enclosures of African Primates (Papio papio and Papio hamadryas) at the Municipal Zoo of Bauru, São Paulo State, Brazil

open access: yesJournal of Medical Primatology, Volume 55, Issue 3, June 2026.
ABSTRACT Toxoplasmosis is one of the most prevalent parasitic infections in animals and humans worldwide, attracting the attention of many researchers who, in recent decades, have identified the sources of Toxoplasma gondii infections to optimize the adoption of preventive measures. In previous studies, it has been found that humans are infected mainly

Sex chromosome-to-autosome transposition events counter Y-chromosome gene loss in mammals [PDF]

open access: yes, 2018
Background: Although the mammalian X and Y chromosomes evolved from a single pair of autosomes, they are highly differentiated: the Y chromosome is dramatically smaller than the X and has lost most of its genes.

Dilated Cardiomyopathy and Aortic Thrombosis in a Capuchin Monkey (Sapajus apella)

open access: yesJournal of Medical Primatology, Volume 55, Issue 3, June 2026.
ABSTRACT This case report describes a capuchin monkey (Sapajus apella) that presented with bilateral paralysis and cold hind limbs. Clinical examination, including ultrasound imaging, revealed dilated cardiomyopathy and aortic thrombosis. Macroscopic, histopathological, and immunohistochemical analyses confirmed these findings.

Hominoid‐specific calretinin‐immunopositivity of the optic radiation (geniculocalcarine tract)

open access: yesThe Anatomical Record, Volume 309, Issue 5, Page 1343-1367, May 2026.
Calretinin‐immunostained coronal section through the primary (V1) and extrastriate (ExSt) cortex of the lar gibbon. Note that the optic radiation (OR) is strongly calretinin‐immunoreactive. This calretinin‐immunopositivity of the OR distinguishes the Hominoidea from other primates in terms of the neurochemistry of the OR.

Can vocal conditioning trigger a semiotic ratchet in marmosets? [PDF]

open access: yes, 2015
The complexity of human communication has often been taken as evidence that our language reflects a true evolutionary leap, bearing little resemblance to any other animal communication system.

Thioacetamide-induced hepatic fibrosis in the common marmoset

open access: yesExperimental Animals, 2018
The common marmoset (Callithrix jacchus) is a nonhuman primate that is used for preclinical research on stem cell transplantation therapies due to its similarity to human beings as well as its small size, enabling researchers to perform experiments without preparing a large number of cells.
