Rapid change.

The increased rate of mutations that led to rapid evolution renders them directed .

Rapid change in phenotype doesn't necessarily imply an increased mutation rate. Rather, new and strong selection pressure can be working on existing variation.

If strong selection pressures is the only couse, which might well be true, then it has to clearly beyond any doupt be proved; and particularly it has to be sure that other co-working couses are excluded.

I think that I agree with Percy that you should take your ideas to the thread proposal that you made earlier, because we'll be wandering off the topic of the Wright paper if we discuss this. I was replying to a comment you made on rapid change in the fossil record, which doesn't directly relate to this topic at all.
