I agree about the evolution part. The great kilt evolved into what we have today and call a "traditional kilt." It may change slightly in the future, but I'm just saying that some people don't believe the Utilikilt is a kilt at all; therefore, not a true evolution of the same garment. The dog analogy doesn't necessarily hold; for example, you can say that a Utilikilt is a garment without leggings, and a kilt is a garment without leggings. It doesn't follow that a Utilikilt is, therefore, a kilt.
