Questioning the Tree of Life

I'm going to Halifax NS (Canada) next week to attend a very exciting conference with a catchy title: Questioning the Tree of life. This is legitimate scientific debate about the tree of life metaphor and its validity in light of massive horizontal gene transfers (HGT, also known as lateral gene transfers - LGT) during the early evolution of single cell organisms. It brings together scientists and philosophers who share an interest in this problem. Should be a blast!

I'm supposed to report the meeting on my blog but I don't know where I'll find the time. Here are the main speakers.

Have a great time in my hometown!

I can already envision the Creationist summaries of the conference, trumpeting the collapse of "Darwinism."

I will be attending at least a few of the talks over the couple of days that the conference is going on. Of course many of the speakers are from the research group I am a PhD student in but there are a lot of really great people going to be here giving some excellent talks.

Mazur, I'm sure, is already prepping a lengthy series of articles on this...
