Koalas have human-like fingerprints.
“Koalas … feed by climbing vertically onto the smaller branches of eucalyptus trees, reaching out, grasping handfuls of leaves and bringing them to the mouth,” the researchers wrote in their landmark paper. “Therefore the origin of dermatoglyphes [fingerprints] is best explained as the biomechanical adaptation to grasping, which produces multidirectional mechanical influences on the skin. These forces must be precisely felt for fine control of movement and static pressures and hence require orderly organization of the skin surface.”[1]
