11 : Duodecimal Sunset
The decimal system is widely favored for the simple reason that we have ten fingers. Each abstract quantity from 0-9 can be counted on each of our long fingers. Had our primate ancestors evolved with twelve fingers, perhaps humans would have adopted the duodecimal or Base-12 system for counting. However, this inadequacy in no way stopped us from exploring the option, as well as higher numerical systems.
