The most viewed posts on Haldane’s Sieve in May 2015 were:

• Chromosomal rearrangements as barriers to genetic homogenization between archaic and modern humans. Rebekah Rogers describes an analysis of chromosomal rearrangements in the Neandertal and Denisovan genomes.
• An empirical approach to demographic inference. Peter Ralph describes a new approach to thinking about demographic inference in the context of a fixed pedigree.
• Sharing and specificity of co-expression networks across 35 human tissues. Pierson et al. develop methods for inferring gene co-expression networks, and apply them to the GTEx data.
• Author post: Coalescent times and patterns of genetic diversity in species with facultative sex. Matthew Hartfield describes his preprint (with co-authors) on coalescent modeling in species that switch between sexual and asexual reproduction.
• A Coalescent Model of a Sweep from a Uniquely Derived Standing Variant. Berg and Coop develop analytical theory to describe the effects of a selective sweep from standing variation on patterns of genomic diversity.
