A three-million-year-old fossil of a toddler-aged hominid, Australopithecus afarensis, reveals children could walk upright as well as climb trees. A report published by 'Science Advances' looked at a thumb-sized fossilized foot from the partial remains of a two-and-a-half year old female named 鈥淪elam鈥 found in the Dikika region of Ethiopia. According to Dartmouth College鈥檚 Jeremy DeSilva, 鈥淭his foot is very human-like and indicates that the Dikika child was walking on two legs 鈥 However, the bone at the base of our big toe鈥攃alled the medial cuneiform鈥攈as a connection for the big toe that is more curved and slightly more angled than what is found in humans today. Such a curved surface would allow motion of that big toe鈥攚hich modern apes use for grasping. We conclude from this, and from previous studies on the shoulders of the Dikika child, that she would have been able to climb, and to also grasp onto her mother during travel.鈥 馃摲 Zeray Alemseged fossil oldschool science: A three-million-year-old fossil of a toddler-aged hominid, Australopithecus afarensis, reveals children could walk upright as well as climb trees.
