According to Stony Brook, New York Science News Report, Study of bones of the hand and wrist Paranthropus bosi Paleoanthropologist Carrie Mongley of Stony Brook University and her colleagues suggest that this 1.5-million-year-old hominid may have had a human-like grip, capable of making basic tools for cutting and shelling. The fossils, in addition to skull fragments, jaw fragments and teeth, were also discovered near Kenya’s Lake Turkana in 2019 and 2021. Mongley explained that the individual’s thumb and fingers would have been able to perform human-like pinching movements, while gorilla-like features suggest that it would have known this. P. Boisi A powerful grip was also useful for manipulating tough edible plants. Fingers and toes, of P. BoisiHowever, tree climbers were not as curved as modern monkeys. It’s not clear how the hominid is doing, added team member Thomas Cody Prang of Washington University in St. Louis. “P. Boisi It can flex its big toe upward while walking, which is the main movement that human feet use when pushing off the ground. P. Boisi The toe was shorter than that of modern humans, indicating that its push-off motion was less efficient while walking, he said. go The nature To read the academic paper exploring this research.

Subsequent studies of fossils suggest that early hominids may have developed tool principles.
