Since the advent of molecular science, Darwinism has leaned heavily on genetic mutations to augment weaknesses observed in natural selection. Today, much of the evolutionists' attention has focused on a set of genes referred to as homeobox (Hox) genes, which are pieces of DNA that either promote or inhibit other genes that play a role in the development of a particular organism. Using this information, scientists have been able to produce organisms with superfluous ectopic appendages, wings, or eyes on various regions of their bodies. This has caused evolutionists to proclaim that they have uncovered an adequate mechanism supporting the concept of evolution by mutations. However, Hox genes are far from the "magic bullet" that many have described them as being. While a mis-expressed Hox gene can alter phenotypic expression, it does not do so in a "biological vacuum." Numerous other genes and proteins are needed downstream in order to produce phenotypic characteristics. Additionally, Hox genes are unable to produce new material-something that is essential for macroevolution. The data generated from researchers investigating Hox genes provide many insights into cellular physiology and development; however, the data do not support or confirm evolutionary theory.
