Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

The Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

The Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

The Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

Tracheal chambers as a key innovation for high‐frequency emission in bat echolocation

The Anatomical Record, EarlyView.
Abstract Key innovations are pivotal for biodiversity and facilitating evolutionary success, enabling organisms' adaptation to various ecological niches through the diversification of phenotypic traits. In mammals, notable adaptations include evolving hypsodonty for grazing on grasses and, for bats, evolving echolocation and wing acquisition.
