Phylogenetic analyses suggest that violations of “Dollo’s law”—that is, re-evolution of lost complex structures—do occur, albeit infrequently. However, the genetic basis of such reversals has not been examined. Here, we address this question using the Drosophila sex comb, a recently evolved, male-specific morphological structure composed of modified bristles. In some species, sex comb development involves only the modification of individual bristles, while other species have more complex…

Macroevolutionary Analyses Provide New Evidences of Phasmid Wings Evolution as a Reversible Process
TLDR
It is demonstrated that wings evolution can be a reversible and dynamic process in phasmids and contribute to shape the understanding of how complex phenotypes evolve.
Repeated horizontal gene transfer of GALactose metabolism genes violates Dollo’s law of irreversible loss
TLDR
The results show how trait reacquisition can occur tens of millions of years after an initial loss via horizontal gene transfer from distant relatives, demonstrating that the losses of complex traits and even whole pathways are not always evolutionary dead-ends.
Genomic resources for multiple species in the Drosophila ananassae species group
TLDR
The ananassae subgroup is an excellent model system for examining the molecular basis of speciation and phenotypic evolution and new genomic resources will facilitate the genetic analysis of inter- and intraspecific differences in this lineage.
Apothecial Ancestry, Evolution, and Re-Evolution in Thelebolales (Leotiomycetes, Fungi)
TLDR
The apothecial ancestry in Thelebolales is demonstrated and a new hypothesis about the evolution of the open ascomata in The Leotiomycetes involving a process of re-evolution where the active dispersal of ascospores appears independently twice within the order.
Compensatory evolution via cryptic genetic variation: Distinct trajectories to phenotypic and fitness recovery
TLDR
It is shown that alleles contributing to compensation of wing morphology have deleterious effects on other fitness components, demonstrating the potential for multiple independent avenues for rapid compensatory adaptation from standing genetic variation, which ultimately may reveal novel adaptive trajectories.
Trpc2 pseudogenization dynamics in bats reveal ancestral vomeronasal signaling, then pervasive loss
TLDR
The Transient receptor potential cation channel 2 (Trpc2) is used as a molecular marker for testing the evolutionary mechanisms of loss and gain of the mammalian vomeronasal system and most families showed independent pseudogenizing mutations in Trpc2, but the reading frame was highly conserved in phyllostomids and miniopterids.

TLDR
Answering fundamental questions about the evolution of key physiological processes will require additional data from genomic, developmental, and fossil data.
Evidence for the loss and recovery of SLAMF9 during human evolution: implications on Dollo’s law
TLDR
This work has determined that the SLAMF9 gene underwent successive mutation events, resulting in the loss of the protein and subsequent recovery of a less stable version, the first known case of the functional loss and Recovery of a gene within the human lineage.
Unraveling the heritage of lost traits.
We synthesize ontogenetic work spanning the past century that show evolutionarily lost structures are rarely entirely absent from earlier developmental stages. We discuss morphological and genetic…

Many ways to make a novel structure: a new mode of sex comb development in Drosophilidae
TLDR
This work describes sex comb development in a species from a more distantly related lineage, the genus Lordiphosa, and suggests that the many‐to‐one mapping between development and adult phenotype increases the potential for evolutionary innovations.

TLDR
The origin and diversification of sex combs provides insights into the roles of modularity, cooption, and regulatory changes in evolutionary innovations, and can serve as a model for understanding the origin of the more drastic novelties that define higher order taxa.
Distinct developmental mechanisms underlie the evolutionary diversification of Drosophila sex combs
TLDR
Phylogenetic analysis shows that similar sex comb morphology in closely related Drosophila species is produced by different cellular mechanisms, suggesting that selection can recruit different cellular processes to produce similar functional solutions.

Developmental constraints and convergent evolution in Drosophila sex comb formation
TLDR
The results suggest that an apparent constraint on SC position in the adult may be attributable to at least two different lineage‐specific developmental processes, although external forces could also play a role.
Hybrid origin of a swordtail species (Teleostei: Xiphophorus clemenciae) driven by sexual selection
TLDR
It is proposed that sexual selection through female choice was the likely process of hybrid speciation, by mating of platy females with males of an ancestral swordtail lineage, as well as artificial crosses of descendent species from the two potential ancestral lineages of X. clemenciae.
EVIDENCE FOR THE REVERSIBILITY OF DIGIT LOSS: A PHYLOGENETIC STUDY OF LIMB EVOLUTION IN BACHIA (GYMNOPHTHALMIDAE: SQUAMATA)
TLDR
It is concluded that there are a limited number of cases with strong evidence for the reevolution of lost morphological structures, raising questions about the mechanisms that retain the genetic information for a latent character.
Recurrent origin of a sexually selected trait in Xiphophorus fishes inferred from a molecular phylogeny
TLDR
A molecular phylogeny of Xiphophorus is presented which differs from the traditional one: it indicates that the sword originated and was lost repeatedly, thus questioning the applicability of the pre-existing bias hypothesis as an explanation for the evolution of this sexually selected trait.
On Phylogenetic Tests of Irreversible Evolution
TLDR
Simulation studies of an irreversible binary character show that false rejections of Dollo's law can be reduced by the use of appropriate existing models and model selection procedures, and show that more powerful tests of irreversibility require data beyond phylogenies and character states of extant taxa.
DOLLO'S LAW AND THE IRREVERSIBILITY OF DIGIT LOSS IN BACHIA
TLDR
It is shown that phylogenetic analyses should incorporate evolutionary mechanisms including constraints, variation, and selection, not only for correct phylogenetic reconstruction, but also for correct evolutionary inference.
