Oh yeah. Steef are the strange ones, with six limbs! Forget the paramites, fleeches and Gabbits, it is the steef that are wierd!
Actually, only a few genes control the most major parts of our body's layout. It would not take a huge mutation to produce more limbs, but controlling them and having a morphology with a place for them is another matter entirely.
There's a good sleg render in TOGG.
