Fossils are rare because their formation and discovery depend on chains of ecological and geological events that occur over deep time. Only a small fraction of the primates that have ever lived has ...

A monkey descending a tree trunk often keeps its head up, moving almost like a cautious climber backing down a ladder.

A new study explains how climbing down trees helped shape upright posture in early primates and changed the course of evolution.

Beyond the research on bone morphology, a UB-led study focuses on soft tissues and expands the methodological tools for understanding how fossil hominids moved throughout the evolution of the human ...

Vertical locomotion in arboreal mammals is shaped by a complex interplay of body mass, limb proportions, grasping abilities, and head mass, and primates use distinct upright postures during descents.

It’s a common mistake to think we came directly from the monkeys or chimps you see at the zoo today, […] ...
