American Journal of Biological Anthropology, Volume 188, Issue 2, October 2025.ABSTRACT Objectives In clinical settings, non‐carious cervical lesions (NCCLs) are often linked to abrasion, erosion, abfraction, or a combination of these factors. In archaeological and paleontological remains, the most common NCCL is the “toothpick groove,” yet little is known about the occurrence of these and other NCCLs in wild non‐human primates ...

Positive selection on the growth hormone and its association with size evolution in Platyrrhini
, 2008 As bases moleculares da diversidade fenotipica dentro de espécies são de grande interesse aos biólogos evolutivos porque a evolução morfológica adaptival depende da seleção de variantes genéticas.

Variación heterocromática del cariotipo, en el Género Cebus que habita en Colombia
Acta Biológica Colombiana, 2001 El entendimiento de la diversidad de los primates es esencial para establecer prioridades en losplanes de su conservación, la taxonomía precede la conservación y en la mayoría de los génerosde los primates Platyrrhini, la taxonomía aún es controvertida. (

The prion protein and New World primate phylogeny
Genetics and Molecular Biology, 2004 The PrP C prion protein contains 250 amino acids with some variation among species and is expressed in several cell types. PrP C is converted to PrP Sc by a post-translational process in which it acquires amino acid sequences of three-dimensional ...

American Journal of Primatology, Volume 87, Issue 9, September 2025.All Callitrichidae have twins who are chimeras, but Callimico has singletons. We examined evidence of blood chimerism in the only known surviving Callimico twins, and found that they were non‐chimeric. This represents the first report of the absence of blood chimerism in twins of any callitrichid species.

A family case of fertile human 45,X,psu dic(15;Y) males [PDF]
, 2006 We report on a familial case including four male probands from three generations with a 45,X,psu dic(15;Y)(p11.2;q12) karyotype. 45,X is usually associated with a female phenotype and only rarely with maleness, due to translocation of small Y chromosomal
