{II} Endogenous Retroviruses: The Three Layers of ERV Evidence for Common Ancestry

[hamzah938]

ATTENTION (TheRationalizer): Well as a self-proclaimed Atheist I owned you pretty good! Your use of the 'F' word and blocking me from comment on your channel was childlike. Your accusation of 'threat by proxy' was a flimsy EXCUSE to avoid my logic, and your hasty retreat avoided defeat.............NOT ! --------------> TOUCHDOWN CELEBRATION ! In your Face ! <----------------

[dookiecheez]

Absolutely brilliant, great video!

[Kuartus]

The erv argument is outdated stuff.

@Kuartus

All but one of your cited links are broken.

[Kuartus]

@FiverBeyond

Actually all the links work. Check that they are being pasted acurately into the adress bar. The other articles answers your questions.

[FiverBeyond]

@Kuartus

I've tried them again and am still getting errors.

[Kuartus]

@FiverBeyond

This time dont paste them into the address bar. I tried it and they weren't being pasted correctly.

[FiverBeyond]

@Kuartus

More importantly, the only like that you've cited that works links to a paper that doesn't address the nested heirarchy found: why should Humans and Chimps share more ervs than both do with Gorillas? Why should these three share more ERVs between themselves than any of them share with Orangutans?

Most importantly: how does Intelligent Design theory predict that we should find this nested heirarchy of shared ERVs?

[Uhlbelk]

@FiverBeyond Your first questions makes no sense or is simply completely obvious. ERV insertion is similar to genetic mutations by other mechanisms. The more recent the two species branched, the less time for more mutations to occur. So the most closely related species have the most shared ERVs and those ERVs that are shared with chimps but not gorillas will have less internal mutations. As for your "Most importantly", intelligent design predicts nothing.

[Uhlbelk]

@FiverBeyond Hmm reading more comments, apparently you were responding to other criticism, sorry, wrong person.

[FiverBeyond]

@Uhlbelk

He he he... I make the same mistake all the time. No harm done.

[Uhlbelk]

@Kuartus OMG there are so many completely wrong statements in creation ministries international that it would take a book to point them all out. "no-phenotype knockout. This is unexpected, because according to the Darwinian paradigm, all genes should have a selectable advantage." completely false, "because redundant genes do not mutate faster than essential genes" is misleading and wrong.... and it goes on and on.

[Kuartus]

@Uhlbelk

Hmm, care to cite some credible papers in favor of your claims?

[Uhlbelk]

@Kuartus I don't need a paper to say "because according to the Darwinian paradigm, all genes should have a selectable advantage" is false. Darwin talked about species as entire entities, i.e. natural selection works on phenotype, but phenotype is not based on a single gene and nowhere in any literature do scientists make that claim.

[Kuartus]

@Uhlbelk

That is not entirely true. An organism which reproduces non essential dna is expending energy in copying it and passing it on. The fact that so much non coding dna exists implies that is serves essential functions. An organism would be at a disadvantage copying useless dna since it is wasting energy and would then be influenced by natural selection into getting rid of it. If a gene is useless then it would be weeded out of the phenotype.

[Uhlbelk]

@Kuartus Evolution does not have the option of thought. It is like a train on railroad tracks, it simply goes forward. If you dump an extra extra car onto it, it continues to go forward unless that car is a sufficient hindrance to make it stop. People have something like 22,000 genes and fast turn over cells can replicate daily. One gene getting duplicated, means nothing to that cell unless it disrupts the metabolic balance of the cell, and energy expenditure will not do that.

[Kuartus]

Sure, but we see that duplicated genes can affect the phenotype enough to cause an organism to be at a serious disadvantage. Down syndrome is one example. It is believe that the extra copy of a gene in the extra 21 chromosome causes abnormal levels of purines which in turn cause retardation. Surely if at the mercy of natural selection, such individuals would perish. Thankfully that is not the case. Besides, there is so much so called "junk DNA" that it would be considerable energy to maintain.

[Uhlbelk]

@Kuartus SOME phenotypes can be influenced by a single gene and others can't, that is why they have whole libraries of genetic knockouts and there is always a list of genes that cannot be knocked out because it would be a lethal mutation. It is also completely false because a gene only has a selectable advantage based on specific conditions/environments that selected for that gene. Once the selective pressure is gone, it is no longer an advantage, this is how vestigial structures come about.

[Uhlbelk]

@Kuartus As for the mutation comment, it is misleading because while mutation in the DNA is generally a constant rate, which makes genetic dating possible, it is misleading because a redundant gene can be non-functional, or changing it will not change the phenotype. This means that the mutation cannot be selected for. His statement is also true of non-coding DNA, but we know that mutates fast enough to distinguish one human from another, or give paternity tests ect...

[siegfried182005]

The most comprehensive explication here on youtube of how ERVs prove common descent by evolution. No wander the idiots attacked your previous channel. I am glad that you re-uploaded these 2 videos, so others like me have the chance to see such a good explanation on the matter in cause!

[TheRationalizer]

Excellent videos. How can people deny this stuff?

[FULLR0B0TICFORM]

to much info for me i think i will read a bible ha ha yeah right lol.

[NematostellaELLA]

great vids!
