Lucy and her fellow australopithecines may have created and used tools more than 3 million years ago, a new study of hand muscles suggests. The finding provides further evidence that tool use started long before the Homo genus emerged.
The researchers focused on hand entheses, which are places where tendons attach muscles to bones. When muscles and joints are used frequently, these attachment sites adapt, resulting in a pattern of bony changes that suggest specific habitual activities.

Homo sapiens, meanwhile, have two key anatomical features that are essential to the ability to precisely grasp, grip and pinch objects, the researchers found.
"More broadly speaking, the co-evolution of the thumb and pinky were decisive for hominin biocultural evolution, setting the stage for the advanced humanlike dexterity we see in humans today," Kunze said.
