Today, I listened to 30 Covert Emotional Manipulation Tactics: How Manipulators Take Control in Personal Relationships by Adelyn Birch. It was a short but intense listen of under two hours. It took more than two hours for me to get through it, because I had to pause to take notes.
As many of you know, Phylotree has not been updated in several years. While I support Phylotree and Dr. Van Oven’s efforts, he has not answered emails in some time either. This is so for both many of you and for myself.
This morning I watched a wonderful video created by Beau of the Fifth Column about MEGA hats, the new harassment free app for those who wear them, and what all who wear those hats could learn about micro-aggression, hate, and making others feel like shit.
Here Dr. Howard Wetsman talks about how making people feel less than others lowers dopamine tone and causes mental health issues. His perspective is on addiction. I think treating others as less than causes many of of our health issues.
In some genetic genealogy circles, they call it the Usry Case. It should not be called that though. It is the ongoing investigation into the murder of Angie Dodge. Angie was 18. A few short weeks after she moved into her first apartment, she was found dead.
This week Brad Larkin wrote a very nice post about the distribution of samples on the Y-DNA tree by country. In it, he looks at many factors including world populations by country. I was really enjoying it until I got to one small paragraph about Y-DNA Q.
It is day six, and we are back to genealogy. The only thing that is going to change PCA ethnic origins into a meaningful product for genealogists and even for personal ancestry enthusiasts is to use markers that date to the genealogical and historic time frames.
Finding the boundaries is itself kind of a frontiering science, so I would say that makes it kind of a science and an art. That quote came out of a recent news article about DNA testing. Surely it was taken out of context. So often quotes in the news are.
This post continues my series on PCA based ethnic origins, what they are meant for, how they work, and what can make them better. This time I will go over what is wrong with all of the visual presentations, the maps, that the companies use.
As I described in Part 2, Principal Component Analysis is a method that can show how alike or different populations of people are. Here, I will show how this method is reversed to attempt to find someone’s ethnic origins.
