Anatomical Evidence for a Uniquely Human Depressor Anguli Oris and a Novel Helplessness Signaling Hypothesis

open access: yesAnnals of the New York Academy of Sciences, Volume 1559, Issue 1, May 2026.
Facial expressions depend on their underlying muscular architecture. Comparative macro and microanatomical analyses and fiber‐level quantification across 10 primate species show that the depressor anguli oris (DAO), the anatomical basis of AU15 (downward pulling of the mouth corner), is uniquely human and lacks a discrete homolog in nonhuman primates ...

The current status of the New World monkey phylogeny

open access: yesAnais da Academia Brasileira de Ciências, 2000
Four DNA datasets were combined in tandem (6700 bp) and Maximum parsimony and Neighbor-Joining analyses were performed. The results suggest three groups emerging almost at the same time: Atelidae, Pitheciidae and Cebidae.

Fungal Diversity and Potential Health Benefits of Mycophagy in Chacma Baboons (Papio ursinus)

open access: yesAmerican Journal of Primatology, Volume 88, Issue 4, April 2026.
Free‐ranging chacma baboons (Papio ursinus) in Nature's Valley, South Africa, of multiple age/sex classes eat diverse fungi (10 identified to species level, 3 to genus level). We assess potential nutritional, medicinal and ecosystem implications of consumption of these fungi based on human and other mammalian mycophagy literature.

Perinatal germ cell development and differentiation in the male marmoset (Callithrix jacchus):similarities with the human and differences from the rat [PDF]

open access: yes, 2013
STUDY QUESTION: Is perinatal germ cell (GC) differentiation in the marmoset similar to that in the human? SUMMARY ANSWER: In a process comparable with the human, marmoset GC differentiate rapidly after birth, losing OCT4 expression after 5–7 weeks of age

The Case of the Missing Green Iguana Predators: Reviews of Ecological Literature Should Go Beyond Google Scholar

open access: yesThe Bulletin of the Ecological Society of America, Volume 107, Issue 2, April 2026.
Abstract Knowing about species interactions is essential for ecological research, conservation efforts, resource management, and maintaining healthy ecosystems, but many of these, such as reports of predation, may not always be published in easily located resources—if they are published at all.
