Mutation plays the primary role in evolution that Weismann mistakenly attributed to sex. Homologous recombination, as in sex, is important for population genetics – shuffling of minor variants, but relatively insignificant for large-scale evolution. Major evolutionary innovations depend much more on illegitimate recombination, which makes novel genes by gene duplication and by gene chimaerisation – essentially mutational forces. The machinery of recombination and sex evolved in two distinct… 

Elimination of altered karyotypes by sexual reproduction preserves species identity.

The reinterpretation of data from the literature strongly supports the hypothesis that the principal consequence of sexual reproduction is the reduction of drastic genetic diversity at the genome or chromosome level, resulting in the preservation of species identity rather than the provision of evolutionary diversity for future environmental challenges.

Uncoupling of sexual reproduction from homologous recombination in homozygous Oenothera species

The first linkage maps of homozygous, bivalent-forming Oenothera species are constructed and provide evidence that HR was exclusively confined to the chromosome ends of all linkage groups in this population.

Origin of the cell nucleus, mitosis and sex: roles of intracellular coevolution

Nuclear pore complexes are evolutionary chimaeras of endomembrane- and mitosis-related chromatin-associated proteins and are the keys to understanding eukaryogenesis: how innovations in one cell component caused repercussions on others.

Complementation, genetic conflict, and the evolution of sex and recombination.

It is shown that asexual reproduction has a short-term disadvantage due to the loss of complementation of recessive deleterious mutations, which can overcome the 2-fold cost of meiosis in one or few generations.

Recombination as a driver of genome evolution : characterisation of biased gene conversion in mice

These findings are consistent with the hypothesis of a selective pressure restraining the intensity of the deleterious gBGC process at the population-scale: this would materialise through a multi-level compensation of the effective population size by the recombination rate, the length of conversion tracts and the transmission bias.

A "meiosis detection toolkit", a set of meiotic genes that represent the best markers for the presence of meiosis that will help to understand both meiotic gene evolution and the capacity for meiosis and sex in putative obligate asexuals.

Genomic Features of Parthenogenetic Animals

Not a single feature was systematically replicated across a majority of these transitions, suggesting that previously reported patterns were lineage-specific rather than illustrating the general consequences of parthenogenesis, and that only parthenogens of hybrid origin were characterized by high heterozygosity levels.

Origin of Sex Revisited

This work challenges the idea that recombinational repair was the major selective force for the emergence of sex and provides arguments that question the putative costs of redundancy in primitive protocells.

THE EFFECT OF SEX AND lVIIXABILITY ON THE EVOLUTION OF AN IDEALIZED GENETIC NETWORK BY CEDOLJUB BUNDALOVIC-TORMA, B.SC

This work modelled the fitness and growth of complexity in sexual and asexual populations in the presence of recurrent mutations which increase the ability of genes to interact with one another.

This overview attempts to trace the history of the search for recombination function in bacteria and their bacteriophages, as well as some of the parallel paths taken in eukaryotic recombination research.

Cell Cycles, Diplokaryosis and the Archezoan Origin of Sex

Genetic error, sex, and diploidy.

It is found that competitive coexistence of an asexual diploid and sexual haploid is possible in spite of the fact that they are competing for a single resource (nucleotide building blocks), and it is indicated that transformation is probably not a diversifying force in bacterial evolution.

The bacterial replicative helicase DnaB evolved from a RecA duplication.

It is hypothesized that DnaB originated from a duplication of a RecA-like ancestor after the divergence of the bacteria from Archaea and eukaryotes, which indicates that the replication fork helicases in Bacteria and Archaea/Eukaryota have evolved independently.

Assembly of RecA-like recombinases: Distinct roles for mediator proteins in mitosis and meiosis

Immuno-double-staining experiments in Saccharomyces cerevisiae suggest that Rad51, the eukaryotic recombinase, can assemble at or near sites containing ssb (replication protein A, RPA) during the response to DNA damage, consistent with a need for mediator activity.

Natural selection, infectious transfer and the existence conditions for bacterial plasmids.

This article presents a general mathematical proof that if plasmids will not be able to persist indefinitely solely by carrying genes that are beneficial or sometimes beneficial to their host bacteria, then such genes should, in the long run, be incorporated into the bacterial chromosome.

Interplay between recombination, cell division and chromosome structure during chromosome dimer resolution in Escherichia coli

The results suggest that the formation of an active XerCD‐FtsK–dif complex is restricted to when a dimer is present, the features of chromosome organization that determine the DAZ playing a central role in this control.

Obcells as Proto-Organisms: Membrane Heredity, Lithophosphorylation, and the Origins of the Genetic Code, the First Cells, and Photosynthesis

It is argued that proteins were primarily structural not enzymatic and that the first biological membranes consisted of amphipathic peptidyl-tRNAs and prebiotic mixed lipids, and that a symbiosis of membranes, replicators, and catalysts probably mediated the origin of the code and the transition from a nucleic acid world of independent molecular replicators to aucleic acid/protein/lipid world of reproducing organisms.
