This is how it works in evolutionary biology, First a single hypothesis is put alone on the table, Second all interpretations of observations have to be made exclusively in light of the only hypothesis and hence used to justify all observations as evidence, Third the very evidence are used to prove the hypothesis.
It’s a fallacious circular reasoning.
You call it DNA evidence but the fact is, it’s DNA observations. Interpretations are what cause the observations to be taken as evidence. But with only one unfalsifiable hypothesis on the table, the interpretations are not credible. All interpretations can be only understood in light of this only (false) hypothesis.
DNA evidence show that a human cell with average diameter of 0.00001 meter includes 2 meter length of human DNA. With enough DNA length in the human body to go from Earth to the Sun and back more than 300 times, or around Earth's equator 2.5 million times!

The DNA sequence is only the beginning of the story; the real story unfolds in the gene expression. The trillions of cells of different types that compose the human body contain exact same DNA but expressed differently through the controlled flow of information from DNA to RNA to protein in a precise process that regulates all functions by adjusting the amount and type of proteins it manufactures to end up with very different and specific functional cells such as nerve cell, heart cell, skin cell, immune cells, etc.
It’s not only the information encoded in the DNA but more importantly how the info is executed to build variety of complex functions through gene expression. A lot of the human genome that was previously considered as junk DNA (does not code for anything) was found to be regulatory genes.
Developmental regulatory genes control the identity of body parts setting up how an animal's body is organized by activating the genes responsible for putting the body parts together, simply were an eye, mouth, leg or tail would be placed.
Regulatory genes start working early in embryonic development to control the identity of body parts; the homeobox (Hox) genes don't give instructions how to create an organ but rather when and where (like the role of a head architect giving instruction for the construction of a building). They just send instructions down the chain of command in a rigid hierarchy. Under this top tier of regulatory genes there are scads of other genes, second tier genes and third tier and fourth tier and on down the line. Aside from that very first one at the top, genes don’t do anything until it's told when how much to do it. It’s not known what activates that first regulatory gene in the top tier to lead all other genes to precisely build a specific functional organism.
Hox genes specify regions of the body plan of an embryo along the head-tail axis of animals. Hox proteins encode and specify the characteristics of 'position', ensuring that the correct structures form in the correct places of the body. Now lets take a general external look at the end product of this process. External morphological features of most multicellular organisms exhibit symmetry that can be seen in the balanced distribution of duplicate body parts or shapes within the body of an organism. The duplicate parts exhibit reflectional symmetry along the axis/plane of symmetry. These external body parts appear almost identical, but are reversed in the direction. Almost a perfect mirror image of the opposite side in a harmonious beautiful proportion and balance.
External vital organs necessary for live such as the nose, mouth, the head itself and
reproductive organs are always aligned with the body on the axis of symmetry (centerline). Other less vital organs (the creature may continue to live without it) such as limbs, ears, and eyes are organized in a reflectional symmetry along each side of the axis.
All parts/organs are organized logically, proportionally sized; symmetrical parts are always a perfect mirror image of the same size. We don’t see limbs longer or one side, displaced or not following the rigid rule of reflectional symmetry. We don’t see multiple eyes on the legs or tail on the head. All species are perfectly designed for survival in its niche. No exception.
Order is the norm not randomness. We’re so used to it to the point that we cannot recognize it or appreciate it. We appreciate light because of our experience with darkness. But we don’t appreciate or even recognize order simply because we never experienced randomness and what it would truly entail.
All living organisms exhibit
perfection as manifested in its body plan balanced morphological features and developmental characteristics with the necessary functions to allow the organism to successfully survive and reproduce with its niche.
The ability of a living organism to successfully survive/reproduce is an absolute prerequisite before any evolutionary process may take place. The emergence of live is not dependent on any evolutionary process; on the contrary no evolutionary process is possible without life as a necessary prerequisite.
The alleged random evolutionary process is always working on the transformation of one already perfect living organism (as explained above) into another.
Logical errors:
A) If the process is random, then selection as a purifying force should not only be involved in the transforming one perfect living organism into another but rather the vast majority of the purification process should be mainly involved in constant correction/elimination of millions of all kind of random errors in a tedious and extremely slow process as entailed by the hypothesis of random gradual change. We don’t see that in nature.
B) If speciation happens mainly due geographic isolation (the new species can no longer interbreed with original species), then the new species will coexist independently along side with original species. Speciation is not a reason for original species to go extinct. This gradual sequencing necessarily predicts enormous number of species and transitional forms, both alive and in the fossil record. We don’t see that in nature.
A team of researchers in Switzerland took a hox gene from a mouse embryo (one that controls the location of an eye) and inserted it into the DNA of developing fruit fly embryo in a region of the fly that would become the back leg
It grew a fruit fly eye next to it’s back leg the instruction of the hox gene from the mouse was not how to make an eye but simply but an eye here. If the alleged evolutionary process is random (not intelligently guided) then we should see all sorts of similar errors such as limbs longer on one side, or body parts in the wrong locations, multiple repeated parts or at least the rigid reflectional symmetry would be broken. We don’t see that in nature.
How the process unfolds is nothing but a clear manifestation of extreme intelligence. It’s impossible to be a product of randomness, because if it was then we have to see evidence of all sorts of random errors (as explained above) that are being constantly corrected through selection. We don’t see that in nature.
Mutations are not random. Genetic evidence is the strongest evidence for the “intelligently guided process”.
All careful studies of mutagenesis confirmed that not only mutations are not random, but also proteins did not evolve via gradual accumulation of change.

Neither genetic evidence support the alleged random change nor the fossil record supports the alleged gradual random transformation via natural selection. The theory is false.
