62:5.2

These two remarkable creatures were true human beings. They possessed perfect human thumbs, as had many of their ancestors, while they had just as perfect feet as the present-day human races. They were walkers and runners, not climbers; the grasping function of the big toe was absent, completely absent. When danger drove them to the treetops, they climbed just like the humans of today would. They would climb up the trunk of a tree like a bear and not as would a chimpanzee or a gorilla, swinging up by the branches.
