    Thanks for the response. Let me try again to get these distinctions clear in
    my head.

    I had asked:

    > 2. Where would genetic relationships among extant and recent species fall?
    > Would that be counted as evidence that there was a (2) process of evolution
    > that occurred, even if details re (3) mechanism are not fully known?

    To which you reply:

    > I would consider genetic homology and other molecular and morphological

    OK, but then I'm led to ask 2 more questions:

    1. What kind of empirical evidence would contribute toward a knowledge of

    2. Does mechanism have to be known before process?
