Any practical use for Universal Common Ancestor?

Goalpost Leviosa!

Echos from under a bridge.

You're confusing the age of the earth with the history of the earth. The history is true no matter what the age is.

Well, considering that the OP is irrelevant to any meaningful purpose, I thought my comment to be appropriate. Sorry that it contradicts your opinion.

It involves extinct fossil species as well since they supply the evidence for phylogeneis that have practical uses.

That's like saying we'd get the same use out of geology if we didn't believe plate tectonics, or the same use out of chemistry if we still believed there were only four elements!

I accept your apology. Never contradict me again.

I fear you are talking complete nonsense, probably due to suffering a serious delusion. Please provide a practical use in medical science or in any form of applied biology for the fossil record.Then, and more to the point, please provide a practical use in medical science or in any form of applied biology for the neo-Darwinian explanation for the fossil record. Good luck with that.Nurse to Doctor Taq: “Doctor Taq, the patient has AIDS. What do you suggest as the first course of action?”
Doctor Taq to Nurse: “Quick! Show me the fossil record!”

I don’t know what you’re talking about. Please make your point with relevant facts and refrain from using evasive and meaningless analogies. (Did you know that mindlessly babbling-on is symptomatic of a damaged cerebellum?)Furthermore, if you can’t think of a practical use in applied biology for the neo-Darwinian explanation for the history of life on earth, just say “I can’t think of a practical use in applied biology for the neo-Darwinian explanation for the history of life on earth.”

You wrote "all this information would have be gained and these uses would have been developed if everyone believed life on earth was 100 years old - which means the Darwinian explanation for the history of life on earth is completely irrelevant to them"But this is incoherent. It's like saying you could get some use out of modern chemistry while still holding in your mind the idea that there are only four elements because the existence of the periodic table is "completely irrelevant"!You asked for "a practical use in applied biology for the neo-Darwinian explanation for the history of life on earth."But in an earlier post I answered this: " If you look it up, you'll find applications to patterns of disease mutation, relative virulence of parasites, handling drug or pesticide resistance, selective breeding ("artificial" selection finds knowledge of "natural" selection useful!), evaluation of possible hazards from genetically modified crops, preservation of endangered species, understanding of gene function (if you know the pattern of descent it helps in learning about genes with still-unknown function), development of biological strains to decompose hazardous materials, genetic algorithms . . ."(and Bellum has other meanings...)

Data on replacement mutations in genes of disease patients exist in a variety of online resources. In addition, genome sequencing projects and individual gene sequencing efforts have led to the identification of disease gene homologs in diverse metazoan species. The availability of these two types of information provides unique opportunities to investigate factors that are important in the development of genetically based disease by contrasting long and short-term molecular evolutionary patterns. Therefore, we conducted an analysis of disease-associated human genetic variation for seven disease genes: the cystic fibrosis transmembrane conductance regulator, glucose-6-phosphate dehydrogenase, the neural cell adhesion molecule L1, phenylalanine hydroxylase, paired box 6, the X-linked retinoschisis gene and TSC2/tuberin. Our analyses indicate that disease mutations show definite patterns when examined from an evolutionary perspective. Human replacement mutations resulting in disease are overabundant at amino acid positions most conserved throughout the long-term history of metazoans. In contrast, human polymorphic replacement mutations and silent mutations are randomly distributed across sites with respect to the level of conservation of amino acid sites within genes. Furthermore, disease-causing amino acid changes are of types usually not observed among species. Using Grantham’s chemical difference matrix, we find that amino acid changes observed in disease patients are far more radical than the variation found among species and in non-diseased humans. Overall, our results demonstrate the usefulness of evolutionary analyses for understanding patterns of human disease mutations and underscore the biomedical significance of sequence data currently being generated from various model organism genome sequencing projects.

Fossils are used to construct the phylogenies used in the direct application described in the abstract.

Do you realize that all you’ve done in your post is repeat yourself . almost word-for-word? Did you know that mindlessly repeating oneself may be symptomatic of a damaged cerebellum?

Do you realize that you can't address the examples of evolution being used in practical applications? Why is that?
