With 83 comments (and counting!) on the latest post about Tutankhamun DNA analysis, you might have missed a link to an article Marianne Luban wrote some time ago. This is what Marianne had to say about it in the comment she left:

For anyone interested in the possibility of a co-regency, the article is here:
