|Common descent: the notion that there is a continuity in the species (all or part of them), in the sense that one is derived “physically” from another. |
Not the best definition. In any case, try to convince your compadres.
|Accepting common descent tells nothing about the cause of it.|
Not "nothing" necessarily, but a reasonable distinction. We can accept common descent and reject natural selection as a mechanism.
|So, again, arguing for gradualism or non gradualism has nothing to do with the problem of cause. Again, the problem of cause remains the most important. The rest are details.|
The family relationship between humans and sunflowers is hardly a mere detail. It is one of the most profound discoveries in human history.
|I just don’t accept that common descent is probably the best explanation for homologies ...|
Oh well. The honeymoon is over.
