There are bits and pieces of every science that get updated and clarified all the time. If you object to moving targets, too bad.
Yes, those would be the non-scientific parts.
The earth orbiting the sun is not going to be falsified by the Pioneer gravitational anomaly.
Yep, I think your right. Good call.
And common descent is not going to be falsified by failure to explain everything right now, today.
Agreed. But that doesn't stop some from trying to explain everything with it.

Yeah, and its really hard to let the old bits and pieces go. Sometimes they survive just as a way of looking at things rather then something that can be tested.
