Would humans hunting a predator to extinction be considered Artificial Selection by your definitions? We determine with our foresight that this species poses a threat to our lives, and become a tremendous selective pressure against it.
This example seems more mundane than proactively selecting crop traits that make cultivation easier. I feel less tempted to claim it as special or artificial, but don't know why in any scientifically justifiable way.
Well in that case we're not selecting which ones to kill and which ones not to kill in order with the intention of producing a new type.
