The DNA methylation revealed a much stronger link to survival than point mutations

http://www.news-medical.net/news/20170320/Methylation-status-of-ten-positions-in-genome-correlates-with-all-cause-mortality.aspx

Excerpt: "Various chemical modifications in the genome determine whether genes are read or deactivated. Methyl labels in the DNA play a key role in this "epigenetic" regulation of gene activity. Life style and environmental factors influence the methylation in the genome. Scientists have already well documented links between the methylation status of specific positions in the genome and cancer as well as other diseases....The DNA methylation revealed a much stronger link to survival than all other previously studied alterations in individual DNA building blocks (SNPs, single nucleotide polymorphisms). The epigenetic risk profile thus proved to be a more accurate indicator for lifespan than all other previously established genetic risk profiles that are based on alterations in DNA building blocks.

"We were surprised that the methylation status of only ten positions of our genome correlates so strongly with all-cause mortality," commented Brenner. "We found even stronger links to mortality from cardiovascular diseases. Now it is important to find out which prevention measures are most effective to achieve a beneficial impact on the methylation profile and mortality."

My comment: Point mutations are results of bad life habits, poor nutrition, stress and environmental factors. Aberrant methylation patterns trigger sequence alterations, which usually are genetic errors. The DNA methylation is an important element in your genome. It stabilizes the whole DNA, activates/silences genes, keeps faulty genes silenced and is used as an analog information layer on top of genes and histones. Methylation patterns are altered when an organism adapts into different type of diet, climate and other environmental factors. Cancer and other serious diseases and health problems are typically caused by disrupted methylation patterns. These epigenetic layers are often transgenerationally inheritable genomic elements. You can take care of your epigenome by eating healthy food, avoiding smoking, alcohol and other toxins.

Changes in gene sequences alone will never lead to evolution or adaptation. Genes are networked by several grammar-complex information layers and they need epigenetic markers for correct functions. Genes are just RAW libraries for RNA directed cellular mechanisms. The evolutionary theory is a major lie. Don't get lost.

Telegony (microchimerism) is not studied by pseudoscientists because it refutes the theory of evolution http://www.theneonnettle.com/features/1006-study-women-store-dna-from-every-male-they-have-sex-with "A new study by the University of Seattle and the Fred Hutchinson Cancer Research Center has revealed that Women absorb and retain living DNA of every single man they have sex with. When scientists were trying to determine if women who had been pregnant with a son might be more predisposed to diseases usually found in men, then also found in the study that the female brain also absorbs male DNA." "Le Dantec wrote that some farmer told him that once his swine copulated with a boar and their pigs absolutely resembled the father in color. But when the same swine copulated with another boar some pigs of the second farrow still resembled the color of the male pig the swine had copulated first."   http://modernnotion.com/is-telegony-real/ "Scientists believe the phe...

Early-stage embryos with abnormalities can still develop into healthy babies

Early-stage embryos with abnormalities can still develop into healthy babies http://www.sanger.ac.uk/news/view/early-stage-embryos-abnormalities-can-still-develop-healthy-babies Excerpt: "Abnormal cells in the early embryo are not necessarily a sign that a baby will be born with a birth defect such as Down’s syndrome, suggests new research from the University of Cambridge, the Wellcome Trust Sanger Institute and the University of Leuven, Belgium. In a study published today (29 March) in the journal Nature Communications, scientists show that abnormal cells are eliminated and replaced by healthy cells, repairing – and in many cases completely fixing – the embryo. Researchers at the Department of Physiology, Development and Neuroscience at Cambridge report a mouse model of aneuploidy, where some cells in the embryo contain an abnormal number of chromosomes. Normally, each cell in the human embryo should contain 23 pairs of chromosomes (22 pairs of chromosomes and one pair of sex chr...

DNA methylation is directed by RNA

Cellular differentiation, adaptation and variation of organisms is directed by RNA, not DNA https://www.researchgate.net/publication/24312289_RNA-directed_DNA_methylation_and_demethylation_in_plants Excerpt: "RNA-directed DNA methylation (RdDM) is a nuclear process in which small interfering RNAs (siRNAs) direct the cytosine methylation of DNA sequences that are complementary to the siRNAs. In plants, double stranded-RNAs (dsRNAs) generated by RNA-dependent RNA polymerase 2 (RDR2) serve as precursors for Dicer-like 3 dependent biogenesis of 24-nt siRNAs. Plant specific RNA polymerase IV (Pol IV) is presumed to generate the initial RNA transcripts that are substrates for RDR2. siRNAs are loaded onto an argonaute4-containing RISC (RNA-induced silencing complex) that targets the de novo DNA methyltransferase DRM2 to RdDM target loci." My comment: There are only a few chemical modifications discovered on the DNA and histones; especially methylation and acetylation. But the list o...
