JUSTA:
Told you 100 times, the same way we got dogs from wolves, interbreeding. But from above it seems you have not yet accepted the genetic facts about dogs, so I can understand your confusion.
[...]
Tell you what genius - if you think you are correct, and that dog breeding is analogous to getting all of the human 'races' we have today from a single breeding pair of middle easterners in just a few thousand years, how about you look at the wolf genome:
The wolf reference genome sequence ( Canis lupus lupus ) and its implications for Canis spp. population genomics
and compare it to a handful of dog breeds. Surely you should be able to find that the wolf genome possesses ALL of the alleles that these other breeds do.
Its already been compared, didnt you read anything?
Dog family tree reveals how modern breeds came to be | CBC News
Ok, wow... UM...
A phylogenetic analysis does NOT seek to find the mutated alleles of the original kind...
My gosh...
I mean, did you even look at the picture on that webpage? No wolves were even in the analysis!
Did you bother to click the link to see the actual scientific paper? Of course not! More in a moment...
By golly, look how they all lead backwards to just two.................... Oh my, imagine that, but you shouldn't have to imagine, you were already told that.
LOL!!
Um.. No - 1. that cladogram only referred to modern domestic dog breeds, not ALL canids.
2. The root of the tree is unlabeled, so you cannot even claim that it 'goes back to 2'.
Also - I do enjoy demonstrating that you do not even read, much less understand, the things you reference.
If you had actually read the paper, you would have seen:
"Our analyses were designed to detect recent admixture; therefore, we were able to identify hybridization events that are described in written breed histories and stud-book records. Using the most reliably dated crosses that produced modern breeds, we established a linear relationship between the total length of haplotype sharing and the age of an admixture event,
occurring between 35 and 160 years before present (ybp) "
So unless you think all dogs 'hybridized' away from a single species (impossible!) of wolf in 160 years... Well, never mind. Suffice it to say this is a huge fail on your part.
But I digress.
Ok - I need to copy paste this line from justa here again:
"By golly, look how they all lead backwards to just two.................... Oh my, imagine that, but you shouldn't have to imagine, you were already told that."
Keep that in mind for a second - he says it traces back to just 2 -
“Given the
high degree of sharing of sweeps [genetic signatures] between these ancient samples and modern samples, it seems clear that these dogs descend from a single domestication origin,” Adam Boyko, a geneticist at Cornell University who was not involved in the work, told
The Washington Post in an email.
Great.
And?
From the
actual research paper that press release was based on:
"By calibrating the
mutation rate using our oldest dog, we narrow the timing of
dog domestication to 20,000–40,000 years ago. "
Mutation rate? What?
UH-OH:
"Furthermore, we detect an additional ancestry component in the End Neolithic sample,
consistent with admixture from a population of dogs located further east that may have migrated concomitant with steppe people associated with Late Neolithic and Early Bronze age cultures, such as the Yamnaya and Corded Ware culture."
So much for that "single wolf kind" magically diversifying via hybridization with... itself.. to magically create diversity by somehow mixing up its already present alleles...
Unless you want to posit at least 2 creation events of the original dog-kind?
And it gets worse for you, pally:
"Our results are consistent with continuity of a European-like genetic ancestry from modern dogs through the entire Neolithic period. However, the slightly displaced position of the ancient samples from the European cluster in the PCAs (particularly for CTC) suggests a complex history. We therefore performed unsupervised clustering analyses with ADMIXTURE (SNP array data; Supplementary Fig. 15) and NGSadmix (whole-genome data; Fig. 4 and Supplementary Fig. 16) (Supplementary Note 9) and found that, unlike contemporary European village dogs, all three ancient genomes possess a significant ancestry component that is present in modern Southeast Asian dogs. This component appears only at very low levels in a minority of modern European village dogs. Furthermore, CTC harbours an additional component that is found predominantly in modern Indian village as well as in Central Asian (Afghan, Mongolian and Nepalese), and Middle Eastern (Saudi Arabian and Qatari) dogs (concordant with its position in the PCA), as well as some wolf admixture."
So, sure, MODERN European dog breeds can be traced back to a GROUP of dogs, but ALL MODERN dogs show a MIXTURE of genetic inputs from multiple earlier dog populations.
Looks like it is back to the drawing board for your "hybridization all the way down" farce.
I also suggest you stop relying on press releases, and even more strongly suggest you stop pretending to make scientific arguments until after you take a few years-worth of college classes on the relevant science.
MASSIVE FAIL.
I mean please, they can trace their lineage genetically all the way back to those wolves. Your arguments are false and inconsistent with DNA data. Accept the facts and get over it already....
Pity that your 'references' completely contradict your layman's conclusion.
The saddest part is that the Dunning-Kruger effect is so powerful in you that you will actually think you somehow proved your point and DIDN'T, yet again, make a fool of yourself.
