A few years ago the Junk-DNA theory rescued the evolutionary theory - Today: THERE IS NO JUNK-DNA!
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5570035/Excerpt: "Researchers from the University of Houston in the US found that the functional portion of the human genome probably falls between 10% and 15%, with an upper limit of 25%."
Excerpt: "Graur found that even if the rate of deleterious mutation was very low, birth rates would need to be unrealistically high to sustain the population if 80 percent of the genome were functional. As reported by The University of Houston:
"For 80 percent of the human genome to be functional, each couple in the world would have to beget on average 15 children and all but two would have to die or fail to reproduce…If we use the upper bound for the deleterious mutation rate (2 × 10−8 mutations per nucleotide per generation), then … the number of children that each couple would have to have to maintain a constant population size would exceed the number of stars in the visible universe by ten orders of magnitude."

Excerpt: "For humans, the mutation rate is predicted to be approximately 70-150 mutations per generation, much higher than the limit that was proposed earlier.
If this were the case, scientists have calculated that only 1% of functional data was possible, far less than the 80% prediction given by the ENCODE Project.
After further scientific study was undertaken, however, it was suggested that humans may actually be able to withstand more than 1 deleterious mutation per generation. It was thought that they may, in fact be able to withstand between 2 and 10. Using this information, it is estimated that 10% of the human genome would then exhibit an organism-level function, leaving 90% to be classified as junk DNA."

Excerpt: "Every time human DNA is passed from one generation to the next it accumulates 100–200 new mutations, according to a DNA-sequencing analysis of the Y chromosome."https://www.researchgate.net/publication/269187480_Non-coding_RNAs_Biological_functions_and_applications?fbclid=IwAR2RYi1Zw99F_-87r8sj0Q3z1FqHJQ19dCBHZUwDbSx2jaV4GPsBLO4ThRY
"In addition, there has been an explosion of research addressing possible functional roles for the other 98% of the human genome that does not encode proteins. In fact, >90% of the human genome is likely to be transcribed yielding a complex network of overlapping transcripts that include tens of thousands of long RNAs with little or no protein forming capacity; they are collectively called non-coding RNA."
"The study in the scientific journal Nature shows that a single genetic change in the "junk DNA" long thought to be useless can have serious consequences."
