Nature writer and photographer Chris Clarke is a great fan of yuccas and yucca moths—he’s working on a book about Joshua trees right now—and so he asked me to answer a few questions about the latest research on the evolutionary history of yucca moths, which was just published in the Biological Journal of the Linnean Society. Check out Clarke’s discussion of the mutualism, and our e-mailed interview, on his blog Coyote Crossing. Look for a post about the paper, with some basic explanation of the methods used in it, right here at D&T next Tuesday.
