Abstract

In Reply.—  Drs Bell and Tubbs raise a matter of concern to those who cannot reconcile the process of evolution with their religious convictions.While I appreciate that concern, I must reiterate that new genetic studies strongly buttress the mass of evidence favoring evolution and the continuous nature of the species. Indeed, they delineate some of the genetic mechanisms by which evolution occurs. Even the continuing appearance of mutations in human populations, for example, the hemoglobin S allele with its associated positive and negative selective values, edges us along an evolutionary pathway and indicates that that process is not over. The paleontologic studies and amino acid sequence comparisons referred to by Drs Bell and Tubbs are valuable but crude tools by today's molecular genetic standards. They nevertheless pointed us in the right direction. Evolution and the continuity of life are scientific facts with which Drs Bell and Tubbs and those
