New paper on ABC comparative method

A new paper by Graham Slater and colleagues has just come out "Online Accepted" in Evolution. A direct link to the paper is here. In this article, the authors present a new method in which Approximate Bayesian Computation is used to simultaneously estimate diversification rates & rates of phenotypic evolution in an incompletely sampled tree. Incidentally, I am a (minor) co-author on this article (my contribution was to write some computer code in C that was used in early versions of the software). Check it out.


  1. Thanks for posting this, Liam! And FYI, MECCA 1.0 is now available in package form at my website


  2. Hi Graham. Very cool. Will this eventually be incorporated into the "geiger" library?

    P.S. You can embed links by using html tags, even in comments: e.g., link to MECCA is here.

  3. P.P.S. For the uninitiated, ABC has a wikipedia page, here.

  4. Thanks Liam. I guess I need to improve my commenting skills...

    Yes, MECCA will ultimately find its way into geiger 2.0. The current release can implement a simple BM model, a two-rate model or BM with a trend (note that a strong root prior, such as might come from fossil information, is required for this model to work). The geiger version will implement OU and ACDC too. Any user suggestions/demands are also welcome.
