What is the evolutionary significance in describing the genetic code as "nearly universal"?

Evolutionists use the concept of a universal genetic code to try to support their proposition that all organisms are the product of common descent through the process of evolution. but, the intelligent design and irreducibly complex nature of DNA, which contains the universal code, refutes the evolutionary paradigm, evolution being an unguided, unintelligent, undirected process incapable of generating such specific, functioning complexity found in organisms even at the simplest level.

This does not mean that evolution totally does not exist, only that it is part of the intelligent design of DNA to allow organisms to adapt to their environment and extend their existence, but only at the discrete species level.

The evolutionary significance is that without DNA, the universal genetic code, there is no replication, and without replication there is no evolution. It is not common descent that DNA proves, rather common design. There are no transitional forms or verified genetic mechanisms that establish evolution as the means for the proliferation of life.
