The facts are basically that there exists a crayfish with triple X chromosomes that produces clones of itself.
Your interpretation is that it exists as a new species, thereby proving evolution to be true - change and the growing complexity we see in nature the result of random genetic changes. Since the concept of species is a component of the theory, it really can’t be used as part of the proof. What you are asserting is an interpretation of the facts.
Another interpretation is that a kind of being was brought into existence utilizing the information that had been previously created. This would include matter itself, what we understand as the fundamental laws of physics and chemistry. These come together in the cell, which is the physical building block of the organism, and in multicellular living forms is specialized into tissues, coming together as organ systems, working in harmony within that individual being, a unity of being in itself. The first being of its kind passed on to its offspring the capacity for diversity, to creatively be manifested in different forms and allowing it to participate more fully in its environment. Again what was created was a kind of thing in an individual creature that reproduces it’s own kind.
Because of original sin, creation fell. We are made of the stuff that is the universe, physically in the form of atoms, molecules, cells and multicellular forms, and psychologically in the form of perception, emotions, thought and action. We share in the attributes that are present in animals, although we are not instinctively bound in our knowledge and actions. We are in a sense the means by which the universe is able to relate to itself and the Source of our being. I believe that when we fell in one man, it was not only all mankind, but all of it. This world, from its beginning to its end, arose from that “eternal” state, ontologically preceding the existence of this universe. Time itself is a journey to reconciliation and ultimate communion with the Ground of its being - communion within the Trinity, in and through jesus Christ, the incarnate Word of God.
Under my frame of reference, the marbled crayfish exhibits the effects of death’s presence in this world. Through the inherent properties of matter, there was a glitch affecting information contained in the cell from which it developed. This random event is chaotic to the underlying information and typifies how devolution works. In time, unprotected from the benefits provided by sexual reproduction to multicellular organisms, the ongoing impact of random mutations will kill off the eventual offspring. Natural selection at work, not creative, but destructive.
Same scientific data, a totally different picture, as much science as is evolution. One might say it is evolution turned upside down.
