This interesting paper that calls into question the common interpretation of clinal variation as a result of natural selection.

Clinal variation, that is the gradual change in genetic or phenotypic traits exhibited by populations over a geographical area, is often interpreted as the result of natural selection. In this work, we demonstrated that demography can also shape variation genome-wide generating patterns that are similar to the ones we often attributed to natural selection. You can read these results at bioRxiv and you can discuss them at Haldane´s sieve.
