The first article that I looked       up was his Y chromosome analysis. He was trying to have all humans       derived from Noah's Y chromosome. In order to make something up he had       to root the phylogenetic tree incorrectly and he then made up 3 groups       that he claimed were from Noah's son's.              https://answersingenesis.org/bible-history/native-americans-and-noah/              You can tell how awkwardly he mishandled the data by looking at what the       tree actually looks like.              https://pmc.ncbi.nlm.nih.gov/articles/PMC6707464/              They do not show the outgroup for Figure 1. An outgroup is just a       sequence that comes from a closely related species where all the       individuals involved in the phylogenetic analysis (all the human Y       chromosomes) share the same common ancestor with the outgroup species.       The outgroup was likely chimps. In the middle of figure 1 you can see       the root to the outgroup in the center of the phylogeny. If Biblical       flood mythology were true Noah would be at the center of the phylogeny       because all extant human Y chromosomes would be descended from Noah.       Jeanson misplaces the root and claims that the true root (not Jeanson's       root) actually is a decending lineage from Ham. Noah's sequence would       be among the longer branch length lineages attributed to Ham. You can       tell that Jeanson's groupings are wrong because of the long branch       lengths under Ham that Jeanson claims is denoting time. Jeanson does       not have Noah producing any more children because the Bible doesn't name       any.              You can tell that he did something wrong with the phylogeny because just       ask yourself why only a couple of Ham's children's descendants show the       same temporal branch lengths of the children of his two brothers with       most of Ham's children showing branch lengths much longer than all their       cousins. The length of the branchs is actually sequence differences       between lineages. the A lineage has the greatest sequence divergence       from all the other lineages. You can see why that is from Figure 1 of       the real science paper.              Jeanson's analysis boarders on insanity. The guy likely is insane.              The actual Noahcian phylogeny should show descent from 4 nearly       identical sequences. Noah and his 3 sons. The Y chromosome is less       than 3% of the human genome and we estimate that only 30 to 60 new       mutations are passed on to each offspring from both parents, but usually       more than half come from the father and the mutation rate seems to       increase with age because his sperm producing cells are constantly       dividing while females have produced all their eggs by around 2 or 3       years old. How did Ham produce children with such divergent Y       chromosomes when they might have inherited a single mutation any       generation? The guy is nuts.              What the true phylogeny actually indicates is that if Noah actually       existed then only 2 of his son's may have left any Y chromosome       descendants. One son's descendants never left Africa, and some of the       other son's descendants never left Africa while a portion of them did.       There is no evidence for the existence of 3 male families.              Like mitochondrial maternal lineages there is a constant loss of Y       chromosome lineages over time because once a Y chromosome lineage       produces no male descendants the lineage becomes extinct. You can see       this happening with the loss of surnames. In Japan if you had no sons       you could get someone to marry your daughter and have him take the       family name, but that doesn't work for Y chromosomes. No sons, no Y       chromosome in the next generation. From the Genetic's paper you can see       that there has been periodic loss of lineages (coalescence) to one       branch where there should exist many just in the last couple hundred       thousand years. You can see them in the length of branchs to each new node.              Ron Okimoto              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
