Interesting poster from SMBE 2017, Maps of effective migration as a summary of global human genetic diversity, by Benjamin Peter, Desislava Petkova, Matthew Stephens & John Novembre, of the JNPopGen group of the University of Chicago.

You can read the full poster in the original PDF, or in compressed image. The following are important excerpts:

Aim: To answer the following questions:

• Which regions have high/low effective migration?
• How well is human genetic diversity explained by this pure isolation-by-distance model?
• How does the explanatory performance of EEMS compare to PCA?

Method: It uses the
