So I was browsing the Web the other day and took a personality test, something like what your finger length reveals about you when I found out I can't be a genius because of the way my fingers are.

Why do your fingers have to be of different lengths?

I was pretty determined to find it out, so I did some research.

It looks like evolutionary history still doesn't have a 100% clear answer to this question.

They recently found a skeleton of a guy with a lump at the base of his hand from 1.5 million years ago.

It means humans possibly had hands just like we do now.

Back then, until then, millions of years before their fingers were long and curved, their palms were extra broad and their thumbs were small and weak.

Now let me check in my large encyclopedia who has hands like that.

They can climb tree branches just fine and are perfect at knuckle walking.

But there are certain things they can't dio gripping, squeezing and pinching are all off their talents list.

So what made humans evolve and go from uniformly shaped fingers to what we have today.

The most popular theory says they developed along with tools.

So I have this chimpanzee hand glove here.

Not super precise, but okay, Now let's try using an axe.

Humans realized they needed better tools to survive, and that meant their hands had to become stronger and craftier to be able to both produce and use those new generation tools.

The second theory is much like the 1st 1 it says humans needed to develop two kinds of crucially important grips.

If you've ever seen a picture holding a baseball, you've seen a precision grip.

You can't do it with a chimpanzee hand because you have to hold it between the fingertips and the thumb.

In a power grip, you rep all your fingers and thumb around something again.

Humans had to master both the grips to be able to use tools, and you can't do either with same length fingers.

The third theory has to do with the most basic form of self defense.

You curl your fingers into your palm at the thumb on top for extra stiffness, and there you go.

You just made a fist, and no matter how hard you try, you couldn't do it if all your fingers were the same size and length.

So I see what this finger and thumb diversity is for.

But what if we rewind evolution to a couple 1,000,000 years ago?

So what if there had been some genius human who adapted all the tools to work just fine with the original type of hands?

If that had happened, would be uniform finger species still, and we wouldn't know any different, so we'd be doing just fine.

However, the same smart human or their offspring would have to redesign pens, scissors, keyboards, buttons and the list could go on for a long time because a lot of things were designed for the type of hands we have.

But what if you or I were the exception among billions of others with the usual hands?

In fact, This is not a science fiction kind of question.

About one in 25,000 kids is born with something known as a trifle Langil thumb.

It means their thumb has an extra bone and is just a long as the other fingers.

I can feel an extra bone growing in my thumb.

And now all of them are exactly the same length.

I never realized how easy it was until it became so uncomfortable.

And I went It takes my friend about this whole situation.

I can't even I think I'll go grab a snack.

But first I'll change into that new shirt.

How do I push the button through the hole now?

Maybe something with a zipper will work better.

Oh, speaking of zippers, what do you personally like better buttons or zippers?

I'm normally team buttons but today is different.

Anyway, that was a bad idea to I'll just wear a hoody.

It takes practice to learn how to use the calm.

Hey, can someone please open that door for me from the other side?

The knob clearly wasn't designed for guys like May.

A peanut butter sandwich would help me eat away my sorrows.

Well, of course, this jar just won't open now.

That's a delicious looking piece, so I'll slice it or I won't.

Cutting things isn't my greatest talent at the moment.

Well, I can always have some bread on the bright side.

Something's telling me that that would be crazy.

I think I'm going to leave a fridge note for my roommate to order a pizza or something when I get back.

I don't know how I'm going to type on the keyboard today, but what if it works out fine?

I don't have to grip on to anything for that.
