The first "humans" introduced in the comic were the Overlanders such as Robotnik which have only four fingers. Later, when Sonic Adventure was released, it was pointed out that Station Square was inhabited by humans with five fingers. Later, with the releases of Sonic Adventure 2 and Shadow the Hedgehog (the game), this concept was expanded to include neighboring human-inhabited cities from those games, all of which collectively make up the "United Federation."
By why would there be both humanoids with four and humanoids with five? Perhaps you might think that it would be a simple explanation like a small genetic mutation. Wrong! The answer, /of course/, is aliens! Aliens which dropped a series of huge animal-gene-targeting bombs on the planet because humans killed one of the alien's kind. That's right, trillions of other lives lost for only one loss of their own.
The bombs killed most animal lifeforms including humans. However what life remained mutated radically into the bipedal, talking animals there today... plus humans with either five fingers per hand or the more aggressive, humanoid Overlanders which have four fingers per hand. Then the aliens returned much later to make sure they killed life on that planet for really reals the second time by using a solar-system-destroying bomb, only to have their plans foiled by Sonic running really fast. Which zapped Sonic across the universe... to the inside of a spaceship... 5,094,000,000,000,000,000 miles away... which contained friendly aliens and a breathable atmosphere... who helped him get back home... which he did after he found Tails's parents on another alien world... and all occurred in the span of one year from the time he left.
