Recent selective sweeps in Drosophila were abundant and primarily soft

We recently rewrote our paper on identifying soft selective sweeps in Drosophila and posted version 2 on the ArXiv. In this new version, we (i)¬†focus much more on the possibility of complex demographic scenarios generating detected signatures, (ii) carry out extensive ABC computations to estimate the likeliest adaptive theta for all of our peaks, and (iii) investigate the power of our statistics to detect sweeps of varying “softness” either due to varying adaptive theta values or because the sweeping allele starts at varying initial frequency. In the end, our conclusions remain the same: that recent selective sweeps in Drosophila were abundant and primarily soft.

Please feel free to check out version 2 and send us your comments!
