Did you actually read that article?
It's not talking about determining common ancestry.
It literally has NOTHING to do with the point I raised.
This one is dealing with populations that aren't genetically isolated from one another and then trying to find out if you are a direct descended of one particular specific bloodline that goes back a few thousand years, which again has nothing to do with the point raised.
No need to pretend, it has nothing to do with the point.
Well, it can. This is why one does a DNA test to see if one is or is not the father of a certain child.
Plenty.
Like how we share thousands of ERV's with chimps.
A little less with gorilla's.
Less still with oerang oetangs.
Less still with lions.
The closer related, the more shared ERV's. The further related, the less shared ERV's.
And that's just one type of marker.
Then there's stuff like human chromosome 2, which is a fused one. And when split at the fusion site, we find chromosome 13 that the chimp has and which we are "missing". Off course, it isn't missing: it's fused with chromosome 2.
And on and on.
So what you are saying is that DNA analysis is hard and that there are factors to take in mind which can create difficulties - and that molecular biologists are aware of what these factors are and how they can be recognized.
You're not telling me anything I didn't already know.
But you don't seem aware that what you are quoting, is actually validating my point and not yours.
It's the same as with geology.
It would be neat if we could just go anywhere in the world, dig down and literally "dig through history".
But it's not that simple. Plenty of tectonic and other geological activity can mess with these structures.
And geologists know about those also and are able to recognize them, meaning that they know when a structure is reliable for such study and when it isn't and account for it.
Hilariously, young earth creationists tend to point to such difficulties as well and like to pretend, just like you do here, that therefor it is all unreliable from start to finish.
The epitome of intellectual dishonesty, in other words.
I'm skipping the rest, because it's the same nonsense over and over.
You projecting your ignorance coupled with your dogmatic beliefs that literally
require you to not accept the science of evolution and trying to raise objections that aren't valid at all by engaging in strawmen, misunderstanding, etc.
So yeah..... nothing new under the sun. Same old, same old.
