IN this case, no, I don't need to. I just need to ask against which standard anything can be claimed to deteriorate. The notion of deterioration only makes sense relative to the intentions of a designer. Sure the chromosome is changing, but that's all you can say, because evolution doesn't have intentions. I don't give a toss where they work or even whether the study is bullshit or not, infact if you say that, apart from this egregious error it's good then I believe you. However, it's language like this that can never be correct and only gives the ignorant leverage. Face it, like accidental teleology in neurobiology, accidental appeals to a designer is an all too common error in evolutionary biology. If we are talking about something that is important to us from a societal or personal perspective then we can talk about deterioration relative to our hopes and fears, but something like this that might affect us in a few million years? I don't think so; it's just sensationalising something that is irrelevant to any human concerns. The phrase 'gene poor' is the same mistake, making a value judgement where none can legitimately be made.
You can call it unfortunate language, but as humbleman demonstrates, this unfortunate language will be jumped on with glee by those who really think that there is a designer and everything happens relative to Him.
In this topic the only one who has mentioned a "designer" has been you.
I, on the other side, even laughed of the conclusions made in the link, conclusions based on evolutionary ideas which don't fit with the current reality.
For once, forget "designers" in this issue.
(I started the propagation of DEGENERATION of species since year 2000, and if any religious group is copying it or have found the same process by themselves and uses it to favor their belief in a god or designer, well, I am aside from them. Before finding DEGENERATION I also found a different process which I called it The Recycling Process of Life on Earth. The name of the theory explains it by itself, species do not evolve but recycle. Not to be discussed here, because it's baby food, I prefer going to the big meal, the degeneration of species which is not theoretical but fact)
There is a degeneration process in progress.
It has always been a degeneration process throughout generations in the species.
Look at the root of the theory of evolution. It was called "evolution" because Kant and others thought that current species have come from inferior, worst and simpler species. Kant even wrote that we are descendants of orangutans and chimpanzees, to which he considered as inferior.
This is the idea that Darwin inherited and continued when he wrote his book the Origin of Species. He concluded that his invention "natural selection" acts solely with slow and favorable steps. Darwin took mutations as favorable only.
This is what the theory of evolution has been about, and this is why still is keeping the word "evolution" in its title.
At one point. in the 70's, when the New-Darwinian theory of Evolution replaced the former one, the whole structure was changed and only the main title and subtitles were saved. The failed theory was told it was "updated", but failed theories can't be updated, failed theories are just discarded.
The current theory of evolution, keeps the word "evolution" as a technical term. As it is accepted, a technical term might mean something completely different to what the same word means in common language.
Evolutionists tried to push the idea that also in common language, the world "evolution" solely means "change", implying no arrow.
As you have said above, the theory of evolution doesn't imply any arrow in the changes, and this is because "evolution" on the theory is now a technical term applied in Biology only.
However,
at the end of the day, there is an arrow. The changes in species finally show a specific arrow.
This arrow discards one more time the claims of the theory of evolution.
Degeneration is the arrow.
Degeneration is the evidence. Degeneration is the path.
Regardless of the propaganda and billions of dollars invested to make appear the theory of evolution as valid, a simple but harmful change in nature affecting the elements of the universe and the species on earth is prevailing: Decay-degeneration.
We must be conscious about this reality of species under degeneration, and we must stop following by inertia of belief the theory of evolution which from its very genesis until today have been proved false.
