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.

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals
The Anatomical Record, EarlyView.Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...
