Yoandri Hernandez Garrido, 37, proudly displays his 12 fingers in Baracoa, Guantanamo province, Cuba. His condition, known as polydactyly, is relatively common, but it's rare for extra digits to be so perfect.

Polydactyly or polydactylism (from Ancient Greek πολύς (polus) "many" + δάκτυλος (daktulos) "finger"), also known as hyperdactyly, is a congenital physical anomaly in humans, dogs, and cats having supernumerary fingers or toes. Polydactyly is the opposite of oligodactyly (fewer fingers or toes).

There’s no other reason to take a 24V71 and build an intake manifold that weighs 1,000 pounds and mount eight 6-71 superchargers on top of four others. This is a V24 Detroit Diesel (normally used to power ships) which is two V12 Detroits joined together nose to nose with splined cranks.
