Gene Evolution v Special Creation

JAMA. 1983;250(1):31-32. doi:10.1001/jama.1983.03340010017010

To the Editor.—  The recent article entitled "Mechanisms of Gene Evolution" by Leder (1982;248:1582) details the remarkable achievements that have been made in molecular genetics. However, the article content is based on the assumption that gene evolution is a fact and not an unprovable theory. Conversely, an elegant and detailed description of gene homologies is also cogent support for a common design fundamental to all forms of life.One of the most widely used methods to support molecular evolution is the classic phylogenetic tree based on amino acid sequences in cytochrome c of various species. Yet, it is usually ignored that the tree supporting an evolutionary interpretation is only one of 40 such trees generated by a computer and that it is chosen because it most closely fits "known phylogeny" or assumed evolutionary history.1 Even this tree shows serious discrepancies such as the turtle being more closely related to
