(To me, Ten is a dreadful number, with only 2 and 5 as dividers)

What would be the scientific/cultural impacts if we have 2 or 4 or 8 digits/fingers per hand(besides no base10 number system)? Like..

1)Would human have developed digital computing earlier?

2)The Biblical Ten Commandments ⇒ 12 Commandments... if we have 4 fingers per hand.

3)Imagine the fantastic impact on music and musical instruments if we have 8 fingers on one hand.

4)'Hand jobs' would be conducted differently for 2 or 4 or 8 fingers per hand.

5)The arabs identify pigs as animals with 2 digits per limb; imagine the Islamic narratives if humans have 2 fingers per hand.

......

Well, well...throw in yours...
