There are more than 300 species of primates with hands including apes, monkeys and of course us humans.
The hands are one of the most important part of the body as they are essential for doing everyday things.
So, how much does a hand weigh?
A human hand will be approximately 0.575% of the total body weight.
Giving that the average adult weighs around 180 pounds (81kg), we can say that the average weight of a human hand is 1.03 pounds (0.46 kg).
What makes our hands so special compared to those of most animals, is that along with our four fingers we also have an opposable thumb.
This means that the thumb can work with each finger to form a powerful grip. Something which is not possible with animals.
Altogether the human hand will have 27 bones, including 8 in the wrist, 5 in the palm of your hand and then 2 in each finger and thumb.
The fingers on our hands are some of the most sensitive parts of the human body as they contain more touch receptors and thermoreceptors than anywhere else on the body.
As result, our fingers are very sensitive to temperature, motion, and moisture.
Our fingerprints are a totally unique feature to every single human being.
No 2 fingerprints can ever be the same except for twins.
Yes it’s is possible for twins to have the same fingerprints but the chances are 1 in 100 million.
~ Fun Fact ~
According to surgeons if you had to lose one finger (not that you would ever want that to happen) you should choose the index finger, as it is used the least.
