The genetic causes of convergent evolution.
TLDR
Evidence for parallel and collateral evolution has been found in many taxa, and an emerging hypothesis is that they result from the fact that mutations in some genetic targets minimize pleiotropic effects while simultaneously maximizing adaptation.Abstract:
This Review distinguishes between three distinct routes by which similar genetic changes contribute to convergent evolution and discusses examples from diverse taxa. Convergent genetic evolution might result from the fact that some mutations both minimize pleiotropic effects and maximize adaptation.read more

Progress and Prospects
TL;DR: Improvement in understanding has led in some cases to better management with improved outcome for the patient, whereas in other areas the way is now clear towards a better prospect for the future.

TL;DR: This article analyzed whole-genome divergence between replicate pairs of stick insect populations that are adapted to different host plants and undergoing parallel speciation, and found thousands of modest-sized genomic regions of accentuated divergence between populations, most of which are unique to individual population pairs.

Contentious relationships in phylogenomic studies can be driven by a handful of genes.
TL;DR: A maximum likelihood framework is used to quantify the distribution of phylogenetic signal among genes and sites for 17 contentious branches and 6 well-established control branches in plant, animal and fungal phylogenomic data matrices, finding that resolution in some of these 17 branches rests on a single gene or a few sites.

Contingency and determinism in evolution: Replaying life's tape.
TL;DR: The authors' review of many such experiments indicates that responses across replicate populations are often repeatable to some degree, although divergence increases as analyses move from overall fitness to underlying phenotypes and genetic changes.

Mutations affecting segment number and polarity in Drosophila
TL;DR: The phenotypes of the mutant embryos indicate that the process of segmentation involves at least three levels of spatial organization: the entire egg as developmental unit, a repeat unit with the length of two segments, and the individual segment.

TL;DR: The genomic data suggest that Neandertals mixed with modern human ancestors some 120,000 years ago, leaving traces of Ne andertal DNA in contemporary humans, suggesting that gene flow from Neand Bertals into the ancestors of non-Africans occurred before the divergence of Eurasian groups from each other.

Natural selection in the wild
TL;DR: It is argued that the common assumption that selection is usually weak in natural populations is no longer tenable, but that natural selection is only one component of the process of evolution; natural selection can explain the change of frequencies of variants, but not their origins.

Adaptation from standing genetic variation
TL;DR: There is potential to distinguish between adaptation from standing variation and that from new mutations by differences in the genomic signature of selection.

FLOWERING LOCUS C Encodes a Novel MADS Domain Protein That Acts as a Repressor of Flowering
TL;DR: This study reports that flc null mutations result in early flowering, demonstrating that the role of active FLC alleles is to repress flowering, and proposes that the level of FLC activity acts through a rheostat-like mechanism to control flowering time in Arabidopsis and that modulation of F LC expression is a component of the vernalization response.
