Gene Duplication does not Support Evolution
In their efforts to thwart the work of creationists and Intelligent Design groups, many proponents of universal common ancestor evolution will ignore testing and empirical science, preferring instead to use the complex scientific principle of Making Things Up™. Other evolutionists use this hooey to confirm their biases.
One of these is the concept of gene duplication as a means of producing new genetic information. It supposedly effects evolution, but cannot be supported by actual science. Indeed, one would be hard pressed to find geneticists who believe such a thing.

Creationists argue that the similarity must have existed in the original design because both genes are necessary for survival. Indeed, determining how the gene similarity occurred (i.e., discovering the specific mechanism responsible) is an entirely different challenge than just assuming it has occurred.. . .
A gene duplication event can influence evolution only if the genes duplicated are in the germ cells (the sperm and eggs), not somatic cells which are not passed on to the offspring. And, of the trillions of germ cells, the cell with the duplicated genes must be the one that is fertilized to be passed on to its offspring. And it must normally occur very early in the cell division to ensure that all of the cells in the new organism have the aberration. At the least, the germ cells for the next generation must have the aberrant trait and produce the seeds of the next generation to allow the duplicated gene to become a new cell line and also a new strain of an organism.Additional gene duplications in the germ cells must occur many times. This is the only way a Darwinian process could ensure that the cell has sustained all of the mutations required to evolve a new function.
