We all enjoy cute things. But what constitutes cute? Is 3 legs cuter than 4? Or 8 cuter than 2? Most of us would agree that in an animal 4 is the perfect number of limbs (think cats, dogs, horses, cows, tigers, and soooo many more) versus 8 legs (think creepy crawly spiders). Although we may not find spiders as cute, there is a perfect reason as to why they evolved to have more legs than we consider desirable or even cute. Scientists discovered, that spiders have 8 legs, so that they can still survive when losing a limb. (see: nationalgeographic) On a sillier note - a quick spider joke:
Q: Why do spiders have eight legs?
A: Because if they had six they would be insects!
