We'll finish up our discussion of statistical phylogeography first, focusing on sparg. It's a very new and very promising approach for inferring the history of genetic samples. In contrast to what I said in lecture on Thursday, it does not require resequencing data. It can work with SNPs, it does require that you have a genetic map for the SNPs that you're using. If you're working in a non-model organism, as many of us do, that may mean that we can't take advantage of all sparg has to offer until we have more genomic resources at our disposal.
Here's a a YouTube video from Matt Olson who is the lead author on the paper describing sparg
