Abstract: Pseudogenes are defined as regions of the genome that contain defective copies of genes. They exist across almost all forms of life, and in mammalian genomes are annotated in similar numbers to recognized protein-coding genes. Although often presumed to lack function, growing numbers of pseudogenes are being found to play important biological roles. In consideration of their evolutionary origins and inherent limitations in genome annotation practices, we posit that pseudogenes have been classified on a scientifically unsubstantiated basis. We reflect that a broad misunderstanding of pseudogenes, perpetuated in part by the pejorative inference of the ‘pseudogene’ label, has led to their frequent dismissal from functional assessment and exclusion from genomic analyses. With the advent of technologies that simplify the study of pseudogenes, we propose that an objective reassessment of these genomic elements will reveal valuable insights into genome function and evolution. – Cheetham, S.W., Faulkner, G.J. & Dinger, M.E. Overcoming challenges and dogmas to understand the functions of pseudogenes. Nat Rev Genet (2019) doi:10.1038/s41576-019-0196-1 Published: 17 December 2019

The friend who sent us the abstract also quotes from the paywalled paper:

In addition to the untested hypothesis that evolution has left us with a dichotomy between genes and pseudogenes, the term pseudogene itself asserts a paradigm of non-functionality through its taxonomic construction. Pseudogenes are defined as defective and not genes. This point is highlighted because impartial language in science is known to inherently restrict the neutral investigation between conflicting paradigms[119]. In the case of pseudogenes, the term itself is constructed to support the dominant paradigm and therefore limit, consciously or unconsciously, scientific objectivity in their investigation.

It was in fact Darwinism that prevented the role of pseudo genes from being properly recognized.

As another friend puts the matter, “This is an important paper for documenting that not only is pseudogene function is far more prevalent than we often recognize but also that evolutionary “dogma” has prevented investigation into the function of pseudogenes. The paper’s message is that pseudogenes probably have many more functions than we think and only the false view that they are “junk” prevents us from finding them.”

Remember how important pseudogenes (evolution’s huge library of useless junk) once were?

By now, Darwin could paper his study with goodbye notes.

Let's start with the closest thing to "science-y" that you've come up with: "Without the added 90% junk they wouldn’t be required." Do you have any evidence for this claim or did you just pull it out of your derrière?Sven Mil

From a couple years ago: Junk DNA is bein g discussed over on the skeptical zone. In the discussion Larry Moran made the claim that 90% of the human genome is junk and he could get a human to develop using just his chosen 10%. He says the junk has accumulated over the illions of generations since eukaryotes arose. However there is a problem with that. The problem are the histone octamers used as spools which DNA is wound around to package it in the nucleus. Without the added 90% junk they wouldn't be required. But with all of that junk it wouldn't be possible to package it within the nucleus without the histone octamer spools. So how did blind and mindless processes figure this out and create the spools to solve the problem? Whoops, the problem isn't just the spools, the spools are active as the DNA moves around them to get exposed and align with other sequences on other histone spools. How did blind and mindless processes pull that off? No one can say. Sven never willET

Already have. The existence of histone octamers prove that the length of DNA was expected. It is evidence that said length was intelligently designed. That is because the alternative, that those octamers just happened and just happened to be able to spool that length of DNA an organize it so that it is useful, is beyond absurd. And it is untestable claptrap. Now that the evidence points to an intelligent design origin for said octamers, the evidence that most of the DNA is junk goes out the window. There is obviously a design reason why the DNA is that long. And to ID that reason is for the storage of immaterial information.ET

PavelU, Thanks for citing those two papers. I won't look at the first paper you cited, because it's too old for my taste. :) However, I looked at the second paper you cited -which is very recent- and found some interesting text you may want to review: Evolution of the Drosophila melanogaster Chromatin Landscape and Its Associated Proteins  
The fifth and last chromatin type, BLACK, has not been addressed in this work. Even if it covers approximately half the genome, it is hard to interpret because it is mechanistically poorly understood and its proteins overlap strongly with those of BLUE chromatin.
To place these results in context, we discuss some critical points of our study. First of all, there is currently no complete list of proteins associated to chromatin.
Selecting only known proteins necessarily introduces a bias in the data set; these proteins may not uniformly address all chromatin-related dynamics.
biases remain due to potential experimental and technical issues. For instance, the genome scan may exclude bona fide CAPs due to the search criteria. Thus, one has to keep in mind that the evolutionary trends that we detect can be influenced by a bias in the data set. On a more philosophical note, the proteome used in this study is the current state of knowledge in the field, and as this body of work will be improved upon in the future, so will its interpretation.
we cannot exclude that even if sequences and domains are very similar, the exact role in chromatin organization may be different.
Finally, as with most proposals of a specific unfolding of the evolutionary process, we note that there is an element of speculation present.
Histone Modifications, Gene Regulation, and the Origins of Multicellularity The evolution of (animal) multicellularity is one of the major transitions in evolution. Within the area of (epi)genomics, it has been hypothesized that complexification of chromatin states and in particular the emergence of distinct heterochromatin states lay at the origin of multicellular life
In summary, these studies propose that an elaboration of chromatin states is based on (unique) combinations of histone modifications.
we find diversification of histone marks and the accompanying proteins, and as mentioned earlier, that may allow for a more fine-grained regulatory control over the genome.
Taken together, we affirm the importance of regulatory complexification in the success of multicellular life. Like other studies, our work suggests this regulatory complexification to be linked with the need to control chromatin states and their propagation in an increasingly complex landscape of active and repressive genomic regions.
we need additional studies that focus on different cell types and other species to deepen and broaden that knowledge.
 For instance, we do not know how chromatin states differ in Drosophila over development and between tissues.
Comparing different species is crucial to determine if the evolutionary scenarios that we propose indeed hold true and how they may need to be refined or reconsidered. One future breakthrough we hope for, is that such studies could provide insight into new BLACK-associated proteins and perhaps lead to a better molecular and evolutionary characterization of this type.
we advocate for an inclusion of ncRNA functionality within the analyses on different chromatin states across species. Clearly, our current study is but an introduction that shows the potential exists for new insights into the evolution of the chromatin landscape.
  Perhaps your claim that this paper seems to answer important questions could be taken as valid up to certain point, but note that the paper does not explain how the chromatin histone octamers originated or evolved. it just describes their observations and obviously sprinkle the expected "evolutionary" jargon over the text just to make sure it's acceptable to the censorship. i would respectfully suggest you spend more time doing some serious homework reading carefully the papers you want to cite before you post your comments. You're welcome to cite papers and ask questions about them, but try to refrain from making unsupported claims that make you look very bad in this public forum. My friendly advice. Be aware that the biology research literature is huge and it keeps growing, but it's mainly describing what they observe, answering outstanding questions while posing new ones. That seems the result of the reductionist bottom-up research approach that is generally taken, which seems like a reverse engineering work. Such a path usually generates more questions than it can answer. Specially when it deals with a complex system that was designed top-down. Important issues raised here:
complexification of chromatin states emergence of distinct heterochromatin states combinations of histone modifications diversification of histone marks and the accompanying proteins more fine-grained regulatory control over the genome. regulatory complexification control chromatin states and their propagation in an increasingly complex landscape of active and repressive genomic regions. ncRNA functionality chromatin landscape

Sven Mil It seems like you're assuming that you have a good explanation for all of this, and that everybody should believe the evolutionary propaganda and not require any actual evidence. But instead of just scoffing and ridicule, why not defend your worldview? A blind, unintelligent, mindless effect (it's not even a process). That's what you've got to work with.Silver Asiatic

ET By trial and error, the blind watchmaker creates and breaks things, so Junk DNA is just the untidy workshop where all of the broken parts are left over. These broken parts are preserved generation after generation, along with all of the functional parts. I'd think the trial and error process would be more efficient by now and there should be a continual decrease in coding errors and broken genes. There should be less reason to preserve the junk over a few million years or so also. My point was that the watchmaker is blind and unintelligent. He doesn't care about anything, and doesn't even think he's a watchmaker. Changing the analogy, he's a bull in a china shop. There's a lot of broken glass on the floor. But the claim is that the bull actually built the china shop and all of the glassware. Some of it got broken and he doesn't bother to clean it up.Silver Asiatic

That said, broken genes are evidence for blind watchmaker evolution, ie accumulations of genetic accidents, errors and mistakes.
The blind watchmaker cannot make a mistake because he does not have a purpose or goal in mind. Chemicals cannot produce errors. They do not want or need to survive. A living organism has no greater benefit or value than any collection of inert chemicals does. The fact that we can distinguish Junk DNA from functional DNA is evidence of Design, since everything the blind watchmaker creates should be Junk. The blind watchmaker has no need or interest in functional DNA. An intelligently designed process can have errors or mistakes because it has a goal in producing organisms that live. In that view, life has value and mutations could be a problem. We can speak of "defects" in a design. But as more function is discovered for Junk DNA it may be entirely necessary and useful in the cell. Otherwise, even in evolutionary terms, why would it be preserved?Silver Asiatic
