Speciation and evolutionary genetics

This section considers studies into speciation and the role of inheritance and variation in individuals and among populations in evolution.

  1. Inter-population distance and differences in breeding times are barriers to reproduction that can contribute to genotypic differentiation between populations. Temporal changes in environmental conditions and l...

  2. Both natural and sexual selection are thought to influence genetic diversity, but the study of the relative importance of these two factors on ecologically-relevant traits has traditionally focused on species ...

  3. Divergence within cis-regulatory sequences may contribute to the adaptive evolution of gene expression, but functional alleles in these regions are difficult to identify without abundant genomic resources. Among ...

    Citation: BMC Evolutionary Biology 2011 11:120
  4. The reproductive ground plan hypothesis of social evolution suggests that reproductive controls of a solitary ancestor have been co-opted during social evolution, facilitating the division of labor among socia...

    Citation: BMC Evolutionary Biology 2011 11:95
  5. Human activities, such as agriculture, hunting, and habitat modification, exert a significant effect on native species. Although many species have suffered population declines, increased population fragmentati...

  6. Figs and fig-pollinating wasp species usually display a highly specific one-to-one association. However, more and more studies have revealed that the "one-to-one" rule has been broken. Co-pollinators have been...

    Citation: BMC Evolutionary Biology 2011 11:86
  7. The study of speciation in the marine realm is challenging because of the apparent absence of physical barriers to dispersal, which are one of the main drivers of genetic diversity. Although phylogeographic st...

    Citation: BMC Evolutionary Biology 2011 11:83
  8. PCR-based surveys have shown that guppies (Poecilia reticulata) have an unusually large visual-opsin gene repertoire. This has led to speculation that opsin duplication and divergence has enhanced the evolution o...

    Authors: Christopher RJ Laver and John S Taylor
    Citation: BMC Evolutionary Biology 2011 11:81
  9. Widely distributed species with populations adapted to different environmental conditions can provide valuable opportunities for tracing the onset of reproductive incompatibilities and their role in the specia...

    Citation: BMC Evolutionary Biology 2011 11:68
  10. Females can potentially assess the quality of potential mates using their secondary sexual traits, and obtain "good genes" that increase offspring fitness. Another potential indirect benefit from mating prefer...

    Citation: BMC Evolutionary Biology 2011 11:44
  11. Hybridization or divergence between sympatric sister species provides a natural laboratory to study speciation processes. The shared polymorphism in sister species may either be ancestral or derive from hybrid...

  12. It has been established that mammalian egg zona pellucida (ZP) glycoproteins are responsible for species-restricted binding of sperm to unfertilized eggs, inducing the sperm acrosome reaction, and preventing p...
