why human has five fingers,but not six fingers?

<>The reason is to ensure our mathematical processes. All math procesess are corried out in base 10; if we had twelve fingers they would be carried out in base 12.

Yes, actually! It's called Polydactyly and it is caused by an autosomal dominant allele. Usually the extra digit is just a little extra tissue, but every once and a while a full functioning finger (or toe) can form!

Maybe humans had no fingers at first but as evolution began...we grew more fingers?So perhaps in the future we might have six fingers...

Seems quite disgusting...

it depends upon u r wish. u cut ur finger if u don't want. or.........invent a new surgery to add fingers

any way we don't have 5 fingers but total 20 fingers. including legs

very odd question u will surely get odd answers

Welcome to earth! here we have 8 fingers not 5 not 10 but 8 and 2 thumbs.

i must be an alien cause i have 10 fingers

coz thats the way God created us

It's with something to do with genes.

somebody born with six so ....

It is how we are created.
