I've built a humanoid race who (in a long story short) left their home planet and were forced to leave the planet.
I am not fully sure how they looked like while they were still on their planet, but I am thinking they should look like dwarf-like creatures with stone-colored skin.
right now, I have made them look like the typical 'Gray-man' extraterrestrial. the one most movies and T-shirt picture when you said 'alien'.
Question; is it possible for a dwarf-like race to evolve into the Gray man aliens? how many years do you think that makes this possible or do you think they need to be completely messed up with inbreed/gene experiments before this is possible?
