As I understand it, what the OP is saying is not something any study could ever control for without perfectly preserved DNA from a statistically significant sample of DNA from human populations going back to old generations. Any study that uses DNA collected from modern humans will weed out the DNA of humans whose descendants are not living today. Hence survivorship bias.
The problem is turning your 2 minute analysis into a conclusion instead of an informed question. The Internet is filled with such conclusions; another adds nothing.

Problem is, the internet is also filled with studies that prove or disprove anything you want, best to be skeptical.
I personally don't put much credence into any studies that seriously thinks they can make any factual accurate statements about things that may or may not have happened 250,000 years ago. Science is never settled.
