Re: Irreducibly Complexity and a True Acid Test
Unfortunately for us fundamentalist Christians, the Hijack system is alive and well. Lets say an organism has a gene A'. The organism undergoes a replication error and now has two A' genes. It only needs one, and having two is not a survival problem. Organisms tolerate a surprising amount of useless DNA for a good reason. With two A' genes, one can mutate randomly without hurting the organism. The organism may find the new gene A'' is useful for a completely different purpose. Sometimes we find both genes active and sometimes A' has disappeared and been replaced, leaving only A''. Sometimes, A' has mutated to A, which does nothing. B' and C' undergo a similar process. Then the organism can combine A,B, and C into an IC process. Then if A', B', and C' disappear, we are left with A,B, and C. Granted it wouldn't happen often, but we do see all these steps happening.
