Interviewed on Youtube

I was recently interviewed by Jackson Wheat, an LSU undergraduate student who has a Youtube channel offering long-form interviews with biologists, skeptics, philosophers, and others working on evolutionary theory and creationism. Check it out!

Are Bacteria Really Like a Soccer Team?

In a footnote to a great paper on bacterial systematics by Laura Franklin-Hall, my attention was drawn to the following aside that John Maynard Smith offers in one of his papers on the same subject. After wondering whether it makes sense to think of bacterial populations as composed of groups of reproductively isolated clones, he muses:

At the opposite extreme, is it better to take a wholly gene-centered view of bacterial evolution, and regard the bacterial cell – or, rather, the bacterial chromosome – as merely a temporary alliance of genes, analogous to a European football team, composed of players from many different countries, all liable to be transferred at any time?1

Getting Started with RLetters

One of the lab’s main products is a suite of tools designed to enable users to perform textual analysis tasks in a user-friendly manner against a corpus of journal articles – a task not common in traditional digital humanities work, which tends to be focused on book-length material. The software is a bit of a challenge to get running, however, requiring some experience in system administration. This post is designed to offer interested researchers a “walkthrough” on how to get a quick server up, running, and loaded with data.

Niches, Red Queens, and Ecological Structure

I was struck the other day by a theme that Richard Lewontin pulls out in a long discussion of the concept of “adaptation” in Scientific American.1 Two common ways of talking about evolution, he argues, wind up embroiling us in a fallacious way of talking about the environment.
