1.   Before that there were many generations of cumulative selection, based upon some quite different replicating entities.

2.   Could a form of cumulative selection get going?

3.   Cumulative selection is the key to all our modern explanations of life.

4.   It therefore is converged upon by cumulative selection from two very different starting points.

5.   The theory of the blind watchmaker is extremely powerful given that we are allowed to assume replication and hence cumulative selection.

6.   Tiny mutations would make cumulative selection too slow.
