Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

The Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

The Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Generation of an HVS-based episomally maintained gene delivery system for reprogramming adult somatic cells [PDF]

, 2012
iPSC technology has the potential to generate patient specific pluripotent cells for use in stem cell therapies and disease modelling. However, current reprogramming methods utilise retroviral vectors, which integrate into the host cell genome disrupting

Purification and properties of Herpesvirus saimiri DNA [PDF]

Virology, 1974
Abstract 3 H-Thymidine-labeled Herpesvirus saimiri (HVS) was purified from supernatant and cells of infected owl monkey kidney monolayer cultures. Pronase/SDS-extracted HVS DNA was characterized in neutral sucrose gradients. Cocentrifugation of this DNA with 14 C-labeled T4-phage DNA resulted in s 0 20 , w = 58 ± 1.5 S as the sedimentation ...

Evolutionary morphology of the haplorhine hamate

The Anatomical Record, EarlyView.
Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.

Biogeography of squirrel monkeys (genus Saimiri): South-central Amazon origin and rapid pan-Amazonian diversification of a lowland primate [PDF]

, 2015
The squirrel monkey, Saimiri, is a pan-Amazonian Pleistocene radiation. We use statistical phylogeographic methods to create a mitochondrial DNA-based timetree for 118 squirrel monkey samples across 68 localities spanning all Amazonian centers of ...

Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult
