Yes, all the edges were the same length. We had a slightly quirky variant of the Hausdorff metric, if I remember correctly. I know Karen’s work somewhat. My roomate back around 1999 / 2000 was a statistician studying phylogenetic trees, and would talk with her at length about this topic with her.

]]>By the way, now that you have a genetic tree, you should look at Karen Vogtmann’s work (with Billera and Holmes) on adapting ideas from outer space (as in Out(F^n)) to phylogenetic trees. http://www.math.cornell.edu/~vogtmann/papers/Trees/

]]>I think there’s a giant list of potential things to study, and geometric topologists have some of the most refined tools for attempting these kinds of experiments. I hope more people make similar experiments, in a wide variety of fields.
