Molecular Origin of Species

  author={Masatoshi Nei and Jianzhi Zhang},
  pages={1428 - 1429}
The making of new species is a fundamental step in evolution, and the molecular basis of this process is just beginning to be worked out, say Nei and Zhang in their Perspective. They discuss two recent examples (one reported by Ting et al. in this issue) in which the concerted evolution of interacting molecules controls reproductive isolation, the first step in the speciation process. 

Topics from this paper

Homeobox genes, fossils, and the origin of species
A model of evolutionary change that is based on the Mendelian inheritance of mutations in regulatory genes and the fact that most nonlethal mutations arise in the recessive state is presented, suggesting that the species barrier between individuals is probably a matter of mate recognition. Expand
Roles of Mutation and Selection in Speciation: From Hugo de Vries to the Modern Genomic Era
It is shown that the currently popular Dobzhansky–Muller model of evolution of reproductive isolation is only one of many possible mechanisms and the root of the currently burgeoning field of plant genomics goes back to Hugo de Vries, who proposed the mutation theory of evolution more than a century ago.

When is a parasite species a species?

The strong potential for the evolution of genetic variability in parasites together with the importance of species diagnosis for applied fields of parasite research make biodiversity research a key role in parasitology. Expand
Conspecific Sperm and Pollen Precedence and Speciation
This review examines case studies, the prevalence of conspecific sperm and pollen precedence, the isolating potential of this class of reproductive barriers, the mechanisms that account for the operation of these barriers, and potential explanations for the rapid divergence of populations in traits related to fertilization. Expand
Accelerated Evolution of the Prdm9 Speciation Gene across Diverse Metazoan Taxa
This work finds that concerted evolution and positive selection have rapidly altered the number and sequence of Prdm9 zinc fingers across 13 rodent genomes, and proposes a hypothetical model in which incompatibilities between PrDM9-binding specificity and satellite DNAs provide the molecular basis for Prdm 9-mediated hybrid sterility. Expand
Rapid evolution and gene-specific patterns of selection for three genes of spermatogenesis in Drosophila.
Evidence of positive selection driving the evolution of Bam is confirmed and an yet unknown germ cell line developmental adaptive change between these two species is suggested, which is a characteristic shared with other degradable transient proteins. Expand
Rapid Evolution of Sex-Related Genes
It is suggested that the combined analysis of intraspecific polymorphism and interspecies divergence will allow to make predictions on whether sex-related genes evolution is driven by conflict or coadaptation between the sexes. Expand
Phylogenetic species recognition and species concepts in fungi.
A phylogenetic approach to recognize fungal species based on concordance of multiple gene genealogies is compared to those based on morphology and reproductive behavior. Expand
Polymorphism in abalone fertilization proteins is consistent with the neutral evolution of the egg's receptor for lysin (VERL) and positive darwinian selection of sperm lysin.
Interestingly, there was a subdivision in the VERL sequences in the pink abalone and a lack of heterozygous individuals between groups, suggesting that the evolution of assortative mating may be in progress, consistent with a model which posits that egg VERL is neutrally evolving, perhaps due to its repetitive structure. Expand
Coevolution of Interacting Fertilization Proteins
Abalone fertilization proteins illustrate how coevolution can lead to reproductive barriers and potentially drive speciation, and present polymorphism-based evidence for positive selection and implicate recent selective events at the specific structural regions of lysin and VERL responsible for their species-specific interaction. Expand


Evolution of gamete recognition proteins.
Although fertilization has been studied for more than a century, the cell surface proteins mediating the process are only now becoming known and diversity of structure may be a recurring theme in the evolution of fertilization proteins. Expand
Genetics and the Origin of Species
This research attacked the mode confusion problem by exploring the role of mutation as a basis for racial and SPECIFIC differences in biodiversity. Expand
Concerted evolution in an egg receptor for a rapidly evolving abalone sperm protein.
Concerted evolution in the egg receptor could explain the rapid, adaptive evolution in sperm lysin and may provide an underlying molecular mechanism that gives rise to species-specific fertilization. Expand
The Divergence of Species-Specific Abalone Sperm Lysins is Promoted by Positive Darwinian Selection.
Analysis of the cDNA sequences shows that positive Darwinian selection must promote the divergence of lysin sequences, indicating that red, white, and flat lysins are more closely related to each other than to the lYSins of the other four species. Expand
Positive selection and sequence rearrangements generate extensive polymorphism in the gamete recognition protein bindin.
These results show that polymorphism in mate recognition loci required for rapid evolution of sexual isolation can arise within natural populations. Expand
Models of evolution of reproductive isolation.
Computer simulations by using Itô's stochastic differential equations have shown that in the model used the reproductive isolation mechanism evolves faster in small populations than in large populations when the mutation rate remains the same. Expand
Specific in vitro interaction between recombinant Strongylocentrotus purpuratus bindin and a recombinant 45A fragment of the putative bindin receptor.
The interaction between recombinant Strongylocentrotus purpuratus sperm bindin and a recombinant fragment of the putative egg bindin receptor of the same species was measured in vitro, showing a specific affinity for one another. Expand
