Biology isn't my thing but I have to think that evolution is going to select what works. Bipedal form with two eyes works best at humanoid size in an environment similar to what we have here on Earth. That might not be the case in worlds with greater or lesser gravity but I'm inclined to think it wouldn't be that much different on other worlds. Same laws of physics, similar solutions.
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
