  In this paper, the authors introduce fundamental work on mathematical methods for inferring evolutionary parameters of interest from RNA data in healthy tissue and during hematopoiesis. By combining single cell and bulk sequencing analyses, the authors use a stochastic process to inform different aspects of genetic heterogeneity; the strength of evidence in support of the authors' claim is exceptional. The work will be of broad interest to cell biologists and theoretical biologists.

  This study presents a valuable new approach for efficient computation of statistics on correlations between genetic variants (linkage disequilibrium, or LD), which the authors apply to quantify the extent of LD across chromosomes. The method appears solid, although the presentation of equations needs clarification and improvement. The authors document that cross-chromosome LD can be substantial, which has implications for geneticists who are interested in population structure and its impact on genetic association studies.

Repeatability of adaptation in sunflowers reveals that genomic regions harbouring inversions also drive adaptation in species lacking an inversion

  This is a valuable comparative study of local adaptation using gene-by-environment and gene-by-phenotype correlations. The analyses seemed still incomplete, as the biological take-home messages were obscured by the statistical approaches used, and it remains unclear how to best interpret the level of genome-wide convergence and in inversions. The repeatability of local adaptation across species, and the role of inversions in local adaptation, are questions of considerable empirical interest.

  This important paper addresses the challenging problem of dating the origin of several groups of marine microorganisms. However, while much of the analyses are solid, the lack of robustness analysis in molecular dating component such as using alternative time calibrations, clock models, and input gene sets makes the study incomplete. Despite some concerns, this work is a commendable attempt at an extremely difficult problem and will be of broad interest to microbiologists, geologists, and evolutionary biologists.

  This important study revises the evolutionary history of Heliconius butterflies, a well-established model system for understanding speciation in the presence of gene flow between species. Using a convincing statistical phylogenetic approach that relies on the multispecies coalescent, the authors reconstruct the evolution of the lineage, including the timing of speciation events and the history of gene flow. The new phylogeny will be of interest to all researchers working on Heliconius butterflies, and the phylogenetic approach to investigators aiming to understand the history of lineages that have experienced extensive gene flow.
