Alright so obviously I should have done some google action before coming up with my incorrect opinion...but what's the real cause then!?!?!?!?! Is is like a chromosome imbalance or could it be caused by something like an extra/flawed chromosome(I think that's what causes things like mental retardation and down syndrome)? WHAT IS IT PEOPLE!?!?!
PS. even with the wobble the spider is still the coolest!!IMO
