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.
