All roads lead to regulation Species from widely divergent taxa can experience similar changes in traits. What underlying genetic drivers cause these parallel changes remains an open question. Sackton et al. looked across groups of birds that have repeatedly lost flight, the ratites and tinamous, and found that there is convergence in the regulatory regions associated with genes related to flight, but not within the protein coding regions. Changes within these regulatory regions influenced limb… 

Noncoding regions underpin avian bill shape diversification at macroevolutionary scales.

TLDR
It is shown that homologs of the identified protein-coding genes as well as genes in close proximity to the identified noncoding regions are involved in craniofacial embryo development in mammals and suggests that identifying genotype-phenotype association on a genome-wide scale over macroevolutionary time is feasible.

Dynamic evolution of transposable elements, demographic history, and gene content of paleognathous birds

TLDR
The evolutionary history of the Palaeognathae populations, genes, and TEs is reconstructed and the findings of co-evolution between mitochondria and W chromosomes highlight the key difference in genome evolution between species with ZW sex chromosomes and those with XY sex chromosomes.

A functional enrichment test for molecular convergent evolution finds a clear protein-coding signal in echolocating bats and whales

TLDR
A generalizable test is developed that offers a resounding “yes” to both extensively debated questions about molecular convergence and how much genomic molecular convergence contributes to convergent phenotypic evolution, such as echolocation in bats and whales.

Non-coding rather than coding regions underpin avian bill shape diversification at macroevolutionary scales

TLDR
The results suggest that regulatory rather than coding changes are major drivers of morphological diversification over macroevolutionary times.

Convergent patterns of gene expression and protein evolution associated with adaptation to desert environments in rodents

TLDR
Convergent changes in gene regulation play a primary role in the complex trait of desert adaptation in rodents, indicating that different instances of adaptation to deserts include a combination of unique and shared changes.

Genomic signatures of the evolution of a diurnal lifestyle in Strigiformes

TLDR
New, owl-specific conserved noncoding elements are identified as candidates of parallel evolution during the emergence of diurnality in owls, shedding light on the molecular basis of adaptation to a new niche and highlighting the importance of regulatory elements for evolutionary changes in behavior.

Comparative Genomics and Evolution of Avian Specialized Traits

TLDR
The genetic bases of trait evolution are demonstrated, highlighting the roles of small-scale sequence variation, genomic structural variation, and changes in gene interaction networks by summarizing previous studies.

Parallel Genomic Changes Drive Repeated Evolution of Placentas in Live-Bearing Fish

TLDR
Comparison of whole genomes of 26 poeciliid species representing six out of nine independent origins of placentation revealed that the evolution of the placenta coincides with convergent shifts in the evolutionary rate of 78 protein-coding genes, mainly observed in transporter- and vesicle-located genes.

Gradual evolution towards flightlessness in steamer ducks *

Flightlessness in birds is the product of changes in suites of characters—including increased body size and reduced anterior limbs—that have evolved repeatedly and independently under similar

Evolutionary Dynamics of Sex Chromosomes of Paleognathous Birds

TLDR
The analysis of Z chromosome evolution and gene expression across 12 paleognaths shows that paleognath Z chromosomes are atypical at the genomic level, but the evolutionary forces maintaining largely homomorphic sex chromosomes in these species remain elusive.

TLDR
A comparative and predictive genomics approach is developed that uses the genome sequences of P. harrisi and its flighted relatives to find candidate genetic variants that likely contributed to the evolution of loss of flight.

TLDR
A phylogenetic analyses of 20 unlinked nuclear genes reveal a genome-wide signal that unequivocally places tinamous within ratites, making ratites polyphyletic and suggesting multiple losses of flight.

Comparative genomics reveals insights into avian genome evolution and adaptation

TLDR
This work explored bird macroevolution using full genomes from 48 avian species representing all major extant clades to reveal that pan-avian genomic diversity covaries with adaptations to different lifestyles and convergent evolution of traits.

Developmental Loci Harbor Clusters of Accelerated Regions That Evolved Independently in Ape Lineages

TLDR
It appears that similar evolutionary processes created independent accelerated regions in the genomes of different apes, and that these lineage-specific changes to conserved non-coding sequences may have differentially altered expression of a core set of developmental genes across ape evolution.

Whole-Genome Analyses Resolve the Phylogeny of Flightless Birds (Palaeognathae) in the Presence of an Empirical Anomaly Zone

TLDR
Distributions of empirical gene trees confirm that the most common gene tree topology for each marker type differs from the species tree, signifying the existence of an empirical anomaly zone in palaeognaths.

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.

TLDR
A genome-scale phylogenetic analysis of 48 species representing all orders of Neoaves recovered a highly resolved tree that confirms previously controversial sister or close relationships and identifies the first divergence in Neoaves, two groups the authors named Passerea and Columbea.
