Interesting new paper: "Proving universal common ancestry with similar sequences"

Just discovered an interesting paper by Leonardo de Oliveira Martins and David Posada.  It is titled "Proving universal common ancestry with similar sequences."  It relates to a paper by Douglas Theobald: "A formal test of the theory of universal common ancestry. Nature 2010; 465:219-22." Although the latter paper is not openly available the more recent one is.  

The new paper is worth a look.  Not sure about the Theobald one as I do not have access from home.

Am hoping Leonardo writes more about this in his blog: Bayesian Procedures in Biology ....


  1. Theobald has followed up his Nature paper with a couple more. There were exchanges in Nature and Biology Direct.

  2. Thanks for the comment! I just wrote a bit more about it here And yes, we talk about his replies as well.
