Have you ever wondered why humans have five fingers? There must be a reason for it.
Evolutionist wonder how things would change if humans had more fingers. The effect is debatable, but there are some people that do have six fingers because of a genetic difference.
Having six fingers would definitely have an impact on learning math since we have a base ten system and children often use their hands to learn this concept.
My theory is that we would have a lot more basketball players that can dunk one handed if we had more than five fingers!
