New insights into how the human hand evolved from our ape-like ancestors

The human hand is an evolutionary marvel. While other primates rely on their hands for locomotion and basic grasping, ours can shape tools, manipulate objects, and perform detailed tasks requiring great dexterity and precision. The evolutionary basis of this unique ability has long been debated, but a new anatomical clue to its origin has just been revealed in a paper published in the journal Proceedings of the Royal Society B: Biological Sciences.
