ORIGINAL: Method You are trying to use modern examples to show that speciation would not produce a nested hierarchy in the absence of horizontal transfer using ERV's specifically. If you are using modern examples then you must include all 200,000 ERV's, not just the handful that differ between any individual human. No, I do not have to show that the alleged ERV's that don't differ among humans would form violations, I just have to show that the recently acquired ones would form violations. All 200,000 alleged ERV's that exist among humans were, according to UCD, acquired sometime in the past and were not all magically inserted into an entire specie all at once. Since there is no reason that the recently acquired ones would form a nested hierarchy then there is no reason for the 200,000 alleged ERV's to form a nested hierarchy at the various times that they were acquired and the organisms possessing them diverged. If UCD is true, we would expect to see a tangled mess. Furthermore, as the organisms further diversify, it would be expected that the alleged nested hierarchy would become blurred and organisms would begin to form a mess as mutations and new ERV's accumulate and form violations from the methods I demonstrated before, especially over millions of years of accumulated violations. This alleged nested hierarchy is not evidence for evolution, it's a problem for evolution, and I think you're beginning to see why. Indeed, the evidence was designed to resist naturalistic explanation to a remarkable degree, not only does this alleged nested hierarchy resist common decent, but it even resists horizontal gene transfer as a mechanism for additional variation (since they would form violations), making it difficult for committed naturalists to speculate any naturalistic unguided mechanism that would form such a phenomena. quote:
Syvanen published a series of papers on horizontal gene transfer starting in 1984 [1], predicting that lateral gene transfer exists, has biological significance, and is a process that shaped evolutionary history from the very beginning of life on earth. ... "While horizontal gene transfer is well-known among bacteria, it is only within the past 10 years that its occurrence has become recognized among higher plants and animals. The scope for horizontal gene transfer is essentially the entire biosphere, with bacteria and viruses serving both as intermediaries for gene trafficking and as reservoirs for gene multiplication and recombination (the process of making new combinations of genetic material)." http://en.wikipedia.org/wiki/Horizontal_gene_transfer Not only does a nested hierarchy resist universal evolution, it even resists horizontal gene transfers as a mechanism having influence on evolution to produce further diversity. Again, UCD is unfalsifiable. UCD does not predict this arbitrary nested hierarchy and a nested hierarchy resists horizontal gene transfer as being a mechanism that aided in the process of creating new combinations of genetic material. quote:
As Jain, Rivera and Lake (1999) put it: "Increasingly, studies of genes and genomes are indicating that considerable horizontal transfer has occurred between prokaryotes."[2] (see also Lake and Riveral, 2007).[3] The phenomenon appears to have had some significance for unicellular eukaryotes as well. As Bapteste et al. (2005) observe, "additional evidence suggests that gene transfer might also be an important evolutionary mechanism in protist evolution."[4] The only reason horizontal gene transfer is speculated here (despite the general lack of observable mechanism) and not in the case of humans and chimps is because in the case of humans and chimps horizontal gene transfer does not fit the pattern. However, in the above example, it more closely fits the pattern so they speculate it as a cause of diversity (or something that helps bring about more diversity). Assuming this alleged nested hierarchy does exist among higher organisms (ie: humans and chimps) and assuming UCD does predict it (which it does not) even if there are violations, they could attribute it to horizontal gene transfer just like they do with prokaryotes. The lack of observable mechanism isn't a problem in the case of prokaryotes and likewise wouldn't be a problem in the case of humans, chimps, and similar organisms. After all, we do observe viruses that can cross the specie boundary, over millions of years it is perfectly plausible for such retroviruses to produce many such violations. Again, this alleged nested hierarchy for higher taxons resists UCD (for reasons stated above) and it resists horizontal gene transfer.
