Also, the article indicates that chromothripsis has been found to occur during the development of tumors, apparently as a result of the breakdown in DNA repair mechanisms. That hardly sounds like an “ancient modeling” process. Even if the phenomena involves any latent genes that occasionally get reactivated, it doesn’t mean they were useful in the past, for speciation or anything else. If they are normally inactive now, the likely reason is that they were harmful mutations. Otherwise, why would their re-activation be associated with disease and cancer?
