Re: [asa] YEC--What can we offer them?

The initial model of continental drift included an unviable mechanism,
as well as some problems on the estimated timing of events, etc.
Fixing these, as well as discovery of critical new evidence, were key
in getting the revised idea of plate tectonics accepted.

I'm not expert in the history of geology, but my impression is that
plate tectonics is largely an example of a new idea explaining
numerous phenomena that had not been linked together, instead of there
being a single previous model that it overturned.
