"Purpose" doesn't seem to be realted to "orientation" at all. "Purpose" generally is realted to "aims" and "goals" which have nothing to do with evolutionary theory. Evolutionary theory has no teleology.

Fine, good doctor. I grant you your assertion for purposes of this discussion. (Of course, the naturalist philosophy unnecessarily behind most of evolution theorists work blocks out questions of ultimate purpose.) I'm using the word purpose as in this sentence, "The purpose of having eyes is to see." The word can be used that way. It really can. I just did. See?
