Radial tree of life

I use a very pretty radial tree of life diagram fairly often — the last time was in my talk on Friday — and every time I do, people ask where I got it. Here it is: it's from the David Hillis lab, with this description:

About this Tree: This tree is from an analysis of small subunit rRNA sequences sampled
from about 3,000 species from throughout the Tree of Life. The species were chosen based
on their availability, but we attempted to include most of the major groups, sampled
very roughly in proportion to the number of known species in each group (although many
groups remain over- or under-represented). The number of species
represented is approximately the square-root of the number of species thought to exist on Earth
(i.e., three thousand out of an estimated nine million species), or about 0.18% of the 1.7 million
species that have been formally described and named. This tree has been used
in many museum displays and other educational exhibits, and its use for educational purposes
is welcomed.

There's also a simplified version:

Both of those are available as scalable pdfs, so you can zoom in and out to get just the right view, which is very handy.

I had a good printer experience, and I thought I should pass it on to you. Printers are, of course, the spawn of Satan. Especially the ink jet kind. For a long time, I had a cheap black and white laser, which worked OK for non color stuff, and an inkjet all in one, which was handy but cost a lot…

Jonathan Eisen has a paper in PLoS One describing software that he's developed for analyzing 16S rRNA sequence data. Rather than walk through everything, I've decided this post will be different: I'm going to treat this as a manuscript that I'm reviewing (there will be some differences, and it…
