A look at DNA through other eyes
This Sunday blog is where The Legal Genealogist shares thoughts about using the cool tool of DNA in genealogical research.
This year, for example, I’ve shared my thoughts about those ethnicity percentages, and why you can’t simply assume that a result of — oh — 25% Irish means you have one Irish grandparent.1 And we’ve looked at the entry of MyHeritage into the DNA field, with its responsiveness to the community’s concerns on privacy issues.2 We’ve considered the changed in the matching system at Family Tree DNA,3 And why DNA isn’t a magic bullet.4
Today, it’s where I want to share the thoughts of others.
Two absolute must-read posts by other genetic genealogy bloggers.
In this critically-important post, Blaine asks the key question we all need to ask about DNA and its use in genealogical research: “When does DNA prove a relationship?” And he offers an answer that may surprise you: “NEVER.” And, he goes on, “this is, perhaps, one of the greatest misconceptions in the post-DNA era of genealogy.”6
His key conclusion: “Whether the DNA evidence supports (versus proves!) a hypothesis or conclusion is an entirely different question, and is the one that should be asked.”7
This is seriously important stuff — and a must-read post.
In this critically-important post, Roberta highlights the risk that overly enthusiastic researchers — and I’ve certainly been in that category more than once myself — can all-to-easily cross the line between encouraging family members to take DNA tests and share their results with us and bullying them into doing do.
She points out that “Bullying is unwelcome aggressive behavior that involves repeated threats, physical or electronic contact or a real or perceived imbalance of power. Generally, the victim feels they can’t make it stop. This has become especially prevalent in the cyber age. And bullying is not just about kids.”9
And, she emphasizes, “genetic genealogy is about genealogy. It’s a hobby. It’s fun. If it becomes otherwise and puts people at jeopardy, then we need to take a step back and take a deep breath.”10
