From The Daily News:

Seven pound Jeshuah Fuller was born yesterday with six fingers on each hand and six toes on both feet. While one in 2,000 babies is born with an extra finger or toe, it's much rarer to have extra digits on each appendage. The trait is much more common among African-Americans.

While Jeshuah is healthy, he will have his extra fingers and toes surgically removed in mid-September. His father, who was born with 6 fingers on his left hand, still has a tiny stump on his left pinkie.

The condition is known as polydactyly and usually an inherited trait.

Famously the family of Foldi, part of the Hyabites tribe living in Arabia, all have 24 digits.
