Back to complexity for a moment.
Here are two open access preprints from PNAS that I found while looking for
the new map of Angkor Wat.
The first is about speeding up artificial evolution by changing the
environment:
http://www.pnas.org/cgi/content/abstract/0611630104v1I haven't read enough to see how they identify the "modules" into which they
decompose the phenotype so they can select different subsets of modules on
each environmental change.
The second, which was published a day earlier, is about the same thing, only
for real. The environment in Madagascar is diverse, but the diverse regions
all share an unpredictable rainfall through the year and year to year. This
unpredictability is proposed to contribute to the unusual diversity of
mammals found.
