The DNA segment not used for long stretches of time is not culled from the genome. Should it not be identifiable as a non selection in a allele cluster? Swept from the genome by a classic selective sweep. quote: No, The tagged gene segment is what genetics has labeled highly conserved. The exact generational transfer mechanism is still unknown. What is sure is that the epigenetic transfer mechanism is far more complicated than the information it transfers. This involves a separate transfer mechanism in chromatin. See some speculation here: How is epigenetic information maintained through DNA replication? | Epigenetics & Chromatin | Full Text Where would you fit this into the evolution paradigm? Let me try to fit it in 1. Genetic Drift.. No, gene segments are highly conserved. 2. Gene Flow No, allele recombination is not a primary mechanism for epigenetic inhearatence. 3. MutationsNo, tags are not initiated by genetic mutation. 4. Natural Selection No, natural selection does not modify the tags. Where do you place it? Edited by zaius137, : No reason given.

quote: Creationists would label all of those earlier hominids apes. I already argued that examination of the human genome shows it is young. John Hawks says that Neanderthals were closer to humans than modern humans today, this drags along all the other so called lines of homo that went extinct. All human.

quote: The evidence is evidence not the interpretation of it. I do not want to overturn science (I am the one using it here to show evolution is wrong). I do not have to overturn evolution because science is overturning it.

That number is proposed by several authorities in the field of genetics, that confirms the calculation I use. I accept your assessment of Taq’s comments. Just to clarify my position: I advocated using the simple exponential growth formula with a local growth percentage to estimate human population growth. I did this because humans alter their environments caring capacity yielding a good short term estimate (local estimate). I also noted the exponential growth rate can be normalized to to end population found here:

Yes, that derived calculation is far better than the simple one I used. I do not dispute that.

The good lawyer example for putting down creationism. I like it. Except all the good lawyers are also the best liars.

quote: Maybe we should discuss this further. Your argument says that indels do not count as divergence percentage between humans and chimps (countable mutations) because they are not SNPs. I get that and got that. What you do not understand is that stand alone SNPs can not account for the differences between chimps and humans. I could reduce this to a simple logic point by saying that we are genetically closer to the HCLCA than to chimps. Now does the HCLCA look more like a chimp or a human? Paleoanthropology would most defiantly say a chimp. But our genes would say that human genes have to be closer to the HCLCA than a chimp. Do you see a dichotomy here? If you like, ignore that point Even if you count each indel as a single mutation because those mutations affect coding (my citations) you get ~125 million mutation events (~45 million in chimp and ~45 million in humans the rest exist in both) regardless of bp lengths. This gives you a best similarity of .125/6.4 or ~2%. I regress back to Nachman, Crowell. t= number of generations since divergence (Generation =20 years)k= percentage of sequence divergence Estimated at 2% Ne= effective size of population ~10^5 (u)=mutation rate 1.1 x10^-8 t= .5(k/u-4Ne) from Estimate of the Mutation Rate per Nucleotide in Humans | Genetics | Oxford Academic You still get a divergence time of ~14 million years. That is giving concessions to the evolutionist. Further differences must be noted in the regulation segments of DNA. Epigenetic’s is just one of those differences. Your right doc...My mistake you must add this to the SNPs 2% + 1.3% gives 3.3% recalculating gives 26 million years since divergence. Edited by zaius137, : No reason given.

New papers showing a drop in human chimp similarity abound. Regardless if the percentage number I used is right, the conclusion is still bad for evolution.
Here is representation of a SNP verses a indel event. Both are mutations and both decrease the sequence similarity (bp count is irrelevant).
Humans and chimps are far different than just 1.3% in their genomes. It seems like a perfect storm in new genetic discoveries all against common descent. Outlining the individual problems from genetic studies: There are not enough mutations available since divergence to accommodate a 95% similarity. 5.6 million years (the fossil nonsense) is below the needed time frame to produce enough beneficial mutations from divergence. Excessive junk DNA in the human and chimp genome is not real. Ancient bottlenecks in small human populations is unstable and can not explain observed linkage disequilibrium in humans. Epigenetic’s can not be explained by Darwinism. There is a mitochondrial Eve and a Y chromosome Adam.
