Neanderthals Could Grasp Tool but Could Not Pick up Coins Due to Different Thumb Structure
News 18A recent research on bones of ancient human ancestors Neanderthals who lived 40,000 years ago has revealed a peculiar quality about their hand structure. The research led by experts from the UK compared the thumb bones in Neanderthals and modern humans and found that the latter could grasp a tool like hammers with ease, but would have faced difficulties picking up a coin. According to the paper published in Scientific Reports, power squeeze grips see objects held between the fingers and the palm with the thumb extended straight and used to direct force. According to new research, the shape and relative orientation of these joints when compared between Neanderthals and modern humans showed different styles of repetitive thumb movements. Researchers believe that this thumb posture suggests the regular use of power squeeze grips, like the ones humans use today to hold tools with handles.
