Consider specifying group sizes in the workshop

[widdowquinn]

We have an opportunity to look at the effect of group size (or effective population size) on virus evolution by, for instance, enforcing that there are a couple of groups of four, up to larger groups of 8-12 - and then comparing the trees that groups of a particular size produce.

We could maybe take photos of the trees that students generate and compose a slide live on the day, to look at the differences - or use the document reader.
