Asexuality is rare in animals in spite of its apparent advantage relative to sexual reproduction, indicating that it must be associated with profound costs [1-9]. One expectation is that reproductive advantages gained by new asexual lineages will be quickly eroded over time [3, 5-7]. Ancient asexual taxa that have evolved and adapted without sex would be "scandalous" exceptions to this rule, but it is often difficult to exclude the possibility that putative asexuals deploy some form of "cryptic… Expand
Deleterious mutation accumulation in asexual Timema stick insects.
TLDR
The idea that deleterious mutation accumulation plays an important role in limiting the long-term persistence of all-female lineages is supported and coding mutations in the asexuals are likely associated with more strongly deleteriously effects than in the sexuals. Expand
Haplotype divergence supports ancient asexuality in the oribatid mite Oppiella nova
TLDR
Positive evidence for the absence of sex over evolutionary time in O. nova is provided and it is suggested that asexual oribatid mites can escape the dead-end fate usually associated with asexual lineages. Expand
Genomic signatures of recombination in a natural population of the bdelloid rotifer Adineta vaga
TLDR
Comparing whole genomes of 11 wild-caught individuals of the bdelloid rotifer Adineta vaga and presenting evidence that some patterns in its genetic variation are incompatible with strict clonality and lack of genetic exchange provide evidence for interindividual genetic exchange and recombination in A. vaga. Expand
Convergent consequences of parthenogenesis on stick insect genomes
TLDR
This study reveals, for the first time, how animal genomes evolve in the absence of sex in natural populations, providing empirical support for the negative consequences of parthenogenetic reproduction as predicted by theory. Expand
Evidence for Ancient Horizontal Gene Acquisitions in Bdelloid Rotifers of the Genus Adineta
TLDR
This chapter conducted a comparative study between these two closely related species using reciprocal best blast hits, followed by functional annotation using the GOANNA pipeline, hypothesizing that these acquisitions may have helped bdelloids to adapt to multiple food sources and to develop enhanced resistance to desiccation. Expand
Repeated evolution of asexuality involves convergent gene expression changes
TLDR
The results provide a rare insight into the molecular basis of asexual phenotypes and suggest that the evolutionary path to asexuality is highly constrained, requiring repeated changes to the same key genes. Expand
Consequences of Asexuality in Natural Populations: Insights from Stick Insects
TLDR
It is shown that predicted consequences of genome evolution under asexuality can indeed be found in natural populations, and strong evidence for higher rates of deleterious mutation accumulation, lower levels of segregating polymorphisms and arrested GC-biased gene conversion in asexuals as compared with sexuals is found. Expand
Genetic Exchange among Bdelloid Rotifers Is More Likely Due to Horizontal Gene Transfer Than to Meiotic Sex
TLDR
It is suggested that bdelloid rotifers evolve asexually but exchange DNA horizontally both within and between species. Expand
Repeated Evolution of Asexuality Involves Convergent Gene Expression Changes
TLDR
The extent of convergent gene expression changes across five independent transitions to asexuality in stick insects is investigated to provide a rare insight into the molecular basis of asexual phenotypes and suggest that the evolutionary path to a sexual orientation is highly constrained, requiring repeated changes to the same key genes. Expand
Recombination in a natural population of the bdelloid rotifer Adineta vaga
TLDR
The complete genomes of 11 individuals from the wild population of the bdelloid rotifer Adineta vaga are compared and it is shown that its genetic structure, which involves Hardy-Weinberg proportions of genotypes within loci and lack of linkage disequilibrium between distant loci, is incompatible with strictly clonal reproduction.

Genetic tests of ancient asexuality in Root Knot Nematodes reveal recent hybrid origins
  • D. Lunt
  • Biology, Medicine
  • BMC Evolutionary Biology
  • 2007
TLDR
The data strongly suggests the tropical root knot nematode apomicts have a recent origin and are not anciently asexual, and support that interspecific hybridization has been involved in the origin of this asexual group and has played a role in shaping the patterns of genetic diversity observed. Expand
PHYLOGENETIC EVIDENCE FOR HYBRID ORIGINS OF ASEXUAL LINEAGES IN AN APHID SPECIES
TLDR
This study constitutes another example that putatively ancient asexual lineages are actually of much more recent origin than previously thought, and presents a robust approach for testing whether hybrid origin of asexuality is also a common phenomenon in aphids. Expand
EVOLUTION IN A PUTATTVELY ANCIENT ASEXUAL APHID LINEAGE: RECOMBINATION AND RAPID KARYOTYPE CHANGE
  • B. Normark
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1999
TLDR
Heterozygosities much lower than intraspecific divergences are found, indicating that some recombination has occurred, but not discriminating between recombination within an asexual lineage (automixis or mitotic recombination) and outcrossing sex. Expand
Heterozygosity, heteromorphy, and phylogenetic trees in asexual eukaryotes.
TLDR
Convergence may be limited by allele sequence divergence and heterozygous chromosomal rearrangements which reduce the homology needed for recombination and result in aneuploidy after crossing-over or ploidy cycles. Expand
Slow molecular evolution in an ancient asexual ostracod
TLDR
Both COI and ITS1 evolve half as fast, at most, in darwinulids as in other invertebrates, and molecular evolution has significantly slowed down in ITS1 of D. stevensoni relative to other darwynulids. Expand
RECENT AND ANCIENT ASEXUALITY IN TIMEMA WALKINGSTICKS
TLDR
Using 416 bp of the mitochondrial COI gene to infer phylogenetic relationships of virtually all known Timema walkingstick species, including extensive intraspecific sampling for all five of the asexuals and their close sexual relatives, found the age of asexual lineages was their geographic position, with younger a sexuals being found further north. Expand
Ameiotic recombination in asexual lineages of Daphnia
TLDR
The rate of loss of nucleotide heterozygosity by ameiotic recombination is substantially greater than the rate of introduction of new variation by mutation, suggesting that the evolutionary potential of asexual diploid species is not only a matter of mutation accumulation and reduced efficiency of selection but also underscores the limited utility of using neutral allelic divergence as an indicator of ancient asexuality. Expand
Genomic signatures of ancient asexual lineages
TLDR
A review and classification of the predicted effects of loss of sex on the eukaryotic genome is presented and the utility of the various predictions for detecting ancient asexuality, for testing hypotheses of the reversibility of a transition to a sexual phase, and for discriminating between theories of sex is discussed.

TLDR
The results suggest that asexual lineages may persist in the short term through dispersal, and that various constraints may cause geographic restriction of sexual lineagess. Expand

TLDR
The observed nuclear and mtDNA genetic structure is consistent with Lasaea clonal diversity being enriched by local mutational derivatives but infrequent recombination cannot be ruled out. Expand
