Human Hand Is Shaped As Per Manual Dexterity, Claims Research
A group of researchers from the University of Utah has taken out a research in which they have studied the evolution of human hand. The study researchers said that human hand has evolved not only by performing delicate tasks, but also because they used it to perform competitive tasks.
Lead researcher David Carrier said, "There are people who do not like this idea, but it is clear that compared with other mammals, great apes are a relatively aggressive group, with lots of fighting".
In order to reach at the above given result, the study researchers assessed the hands of martial arts artists when they used to hit a punch bag. The study, which has been published in the Journal of Experimental Biology, included a survey as well.
The study researchers said that they have used to measures to calculate force and acceleration at the time artists used to punch a bag. Co-author of the research David Carrier said that after assessing the group, they were quite astonished to know that strikes with palms were stronger than the fist strikes.
The study researchers said that the human hand has shaped according to the need of manual dexterity, which was a novel thing to know.
