The Tree of Life, COI-ly
The September 30th issue of the Economist points to an article in PLoS Biology by Hebert, et al, discussing a new technique for identifying species. The technique, which relies on mitochondirial genes for cytochrome [link to http://www-bioc.rice.edu/~graham/CcO.html no longer works] c oxidase I (COI), which is a 648 pair gene. 
This technique helps settle the question of “Is Astraptes fulgerator one species or several?”. The butterfly in question looks the same as a butterfly, but there are important variations in the caterpillar forms.
Which, as I strugle to create a taxonomy for a specific set of computer security issues, shows that I am doomed to fail, and that may just be ok.
 Who the heck told them they could throw a ‘c’ out in the midst of a protien name like that? Do these people have no respect for the English language?
 It was keeping me awake at night, too. (As many as 10 species in Costa Rica alone.)
