[Sonic The Hedgehog] Why are Sonic and his friends anthromorphic while the animals they break out of Eggmans robots are completely normal?

So the original lore was that certain animal species evolved to a more human state after the humans on Sonics home world went extinct. Robotnik isn’t from his home world which is why he’s the only human in the original games. The series has been retconned and changed so much that it’s just kind of become “humans are sometimes part of this world, but not always.”
