Davison clams that natural selection has no role in evolution other than to suppress variation, despite lots of observational and experimental evidence that it can preserve and spread adaptive genetic changes, however they occur. Dismissing any significant role of natural selection or point mutations, he proposes huge, sudden chromosomal changes, but without any means of directing or controlling them, or any explanation as to why they would be preserved and spread. At times he seems to hint that divine guidace or creation is involved, but he does not clarify this, or whether he thinks it’s all “frontloaded” or due to periodic interventions (progressive creation).
