Comments on: Genealogy, Kinship and DNA … https://gregladen.com/blog/2013/04/24/genealogy-kinship-and-dna/ Fri, 26 Apr 2013 16:37:02 +0000 hourly 1 https://wordpress.org/?v=6.4.6 By: Ole Phat Stu (again) https://gregladen.com/blog/2013/04/24/genealogy-kinship-and-dna/#comment-486894 Fri, 26 Apr 2013 16:37:02 +0000 http://scienceblogs.com/gregladen/?p=16442#comment-486894 But seriously : Is there a structured prosopography of the families available? If so, a multivariate analysis (or e.g. the ID3 algorithm) might provide some clues.

Assuming an average generation to be 30 years, that would be 200 generations.

Now, even going only half way back and assuming people have 2 parents (pace Mary) , that would make for 1267650600228229401496703205376 ancestors, more people than have ever lived. Therefore there must have been some inbreeding.

Right, that’s Kansas accounted for 😉

There are those of us who have been putting cousin marriage in proper biological context for decades, and what I’ve seen indirectly of his work looks interesting and basically right, but I’ve not had a chance to read his book.

But yes, the benefits of marrying your cousin may very well outweigh the costs! Of course, since I have no first cousins, that’s easy for me to say. Also, Huxley’s new baby girl cousin is a parallel cousin, and I’m strictly opposed to parallel cousin marriage. Cross cousin marriage, that’s fine but parallel cousins … THAT’S UNNATURAL.

I’m curious — will you be referring to Alan Bittles work on cousin marriage? He was at NESCent for awhile and where I read about “purging” thus kicking deleterious mutations out of the gene pool.
