CoE #25 on Culturing Science

The 25th edition of Carnival of Evolution is ready at Hannah Waters' blog, Culturing Science.

A sample:

As we know, the process of evolution takes an incredibly long time. How do evolutionary biologists study the process of natural selection just in their lifetimes? Two posts this month feature experimental methods to test traditional theories of natural selection.

I'm not sure I know this myself. There's good of evidence that some processes can be very fast (e.g. my favorite Croatian lizards described by Herrel et al., 2008). Yes, some things take millions of years, like the morphological change from terrestrial ungulates to whales, but many other events can be observed in our lifetimes. Another example is Drosophila speciation.
