Actually, with the prelevance of polydactyly (about 1 in 1000 people have 6 or more fingers), and less accidents happening, most people might have a bellow average number of fingers in the future.

There is no way in hell the incidence of polydactyly is that high

Edit: jesus christ you were right

Conclusion: we are not in hell ?

Are you sure? One in 500 babies is born with an extra digit.

Most will have a medical prosecute to remove it
