“The Hillis Plot […] is, in fact, the largest diagram of its kind, created by scientists David Hillis, Derrick Zwickl, and Robin Gutell at the University of Texas.
According to Hillis and his colleagues, the tree was assembled based on the analysis of small subunit rRNA sequences sampled from about 3,000 species — sampled, say the researchers, roughly in proportion to the number of known species from each of the six main groups of cellular life: animals, plants, fungi, protists, bacteria and archaea.
The number of species represented is roughly 0.18% of the 1.7 million that have been formally described and named (out of an estimated 9 million).
The Hillis plot art was first published in Science back in 2003.”

“The largest-scale attempt in that direction so far has been made by a group associated with David Hillis, brother of Danny Hillis who pioneered one of the first supercomputers. The Hillis plot makes the tree diagram more compact by wrapping it around in a circle. You can’t see the gap, where the two ends almost meet, but it lies between the ‘bacteria’ and the ‘archaea’. … The Hillis circular plot is the same, except that it has three thousand species. Their names appear around the outside edge of the circle above, far too small to read — though Homo sapiens is helpfully marked ‘You are here’. You can get an idea of how sparse a sampling of the tree even this huge plot is when I tell you that the closest relatives of humans that it can fit in the circle are rats and mice. The mammals had to be stripped down drastically, in order to fit in all the other branches of the tree to the same depth. Just imagine trying to plot a similar tree with ten million species in stead of the three thousand included here. And ten million is not the most extravagant estimate of the number of surviving species.”
