  This study aims to analyse the effect of polymorphism on meiotic recombination in subspecies of Saccharomyces. The detection of reciprocal and non-reciprocal events is based on sequencing the haploid products of meiosis, and frequencies are compared between strains having introgressed genomic segments and strains lacking such segments. Unfortunately, the method used are inadequate for quantifying the non-reciprocal events.

  eLife Assessment

  This important study provides new and nuanced insights into the evolution of morphs in a textbook example of Batesian mimicry. The evidence supporting the claims about the origin and dominance relationships among morphs is convincing, but the interpretation of signals needs improvement with complementary analysis and some nuanced interpretation. Pending a revision, this work will be of interest to a broad range of evolutionary biologists.

  eLife Assessment

  The study presents a very well-illustrated specimens of the artiopodan Cindarella eucalla from the Chengjiang Biota, using computer tomography (CT) scanning to illustrate multiple specimens with preserved appendages, a rarity in artiopodans. The description of these fossils is important for expanding our understanding of this taxon and its relatives. The imaging and morphological description are followed by a discussion of how this morphology relates to other Cambrian arthropods and its potential ecological function. The evidence provided in this section about resulting function and ecology is presently incomplete and the conclusions are put forward too strongly. This assessment could be improved if the work is revised with more careful wording and additional data.
