Sorry for the late response. I missed the alert that you replied.
They can be the same if a sentient assigner assigns a purpose to itself. If I assign myself the purpose of becoming a doctor and healing the sick, I am both the assigner and the subject to which purpose is being assigned.
Perhaps it comes down to definition. As with many words, there can often be more than one meaning and use. If purpose requires a sentient agent as the assigner, then perhaps another word, like function, would be applied an action or role that has no assigner. In common usage though, I think purpose can be used both ways, to imply an assigner or to be synonymous with function with no assigner implied. It is my understanding that you are implying purpose with an assigner.
With evolution, especially bi-sextual reproduction, there is a constant shuffling of the gene pool, so there is a randomizing element(beyond simple error in transcription or other insults to DNA). And every outcome either survives to reproduce or it does not. There is no mindful culling in nature. It seems hard to imagine how a desired outcome could be achieved under such randomizing conditions.
How can they be the same entity?

This is interesting, so what about evolution? It seems to be a mindless process with no intentions or goals yet our body parts seem to have purposes. What's your take on that conundrum? If it's mindless then it can't assign purpose yet our eyes for example, seem to have been designed for the purpose of sight.
