orthogenesis

[Ken Kinman]

I'm reluctant to get into a semantic debate, but couldn't orthogenesis be regarded as a form of natural selection?  And even if you do separate them, it seems ill-advised to regard one as being of primary importance and the other of secondary importance for ALL evolutionary trends.
