Our ancestors were constantly doing that soijak pointing face.

>>14741998
For pinching, maybe.

pinching is a flexing motion idiot

What do you think muscles are for?

More like /pol/ tourists who cause 99% of the dumb posts here.

the EXTENSOR is for EXTENDING, in the index finger's case going UP. extensor indicis wouldn't help with pinching, as when pinching it uses the flexor digitorum

>what is the evolutionary reason?
The natural process of evolution does not have goals so there is no such thing as an "evolutionary reason." That's like asking what's the "erosional reason" a natural rock arch forms, which is gibberish. The only response is "erosion" itself and then you go on to explain how erosion works because the person who asked that is an idiot who implies the natural process of erosion has goals.
The benefit for this muscle is that it allows for greater dexterity for motor tasks, such as tying an arrowhead to a stick, or more efficiently scooping out food such as bugs from small spaces or fleshy parts of fruit. Tiny primates could greatly benefit from this more-efficient dexterity when they reach into a tiny hole to grab bugs.

shut the fuck up retard

>>14742082
You're confusing flexion and contraction, or you just don't know the difference, fucking retard

>>14745288
Hes right tho

>>14742036
Why are you so mad? Is it because you got exposed as a retard? Pinching is done by the flexors
And a wokaj poster too, you must be from pol or v

Wait until you hear about the extensor digiti minimi

It's OBVIOUSLY to boop people

>>14745288
No. And since your capacity to understand these things amounts to pic related you must leave.

This is the most rancid example of vacuous pseudointellectualism on display today. Well done.

Jokes aside, pointing is very useful. if you've ever been to a country where you don't know the language you'll know how far just pointing at things will get you.
Imagine especially before language was a thing, just how useful pointing was

Interestingly, chimps don't use pointing in the wild. More specifically, it's extremely rare they show a directional-like gesture and when they do it's debatable they're even using it for communication. They absolutely don't use the index finger to point in the wild.

Elephants have been observed to understand human pointing without training and they're the only animal to do so.

Dogs do too, that is one aspect in how they differ from wolves.

Are you guys retarded? He's compeltely right. Dumb shit evolves all the time, life isn't the perfect efficiency machine you want it to be
