Summary

Biological speciation impacts sexually reproducing species by influencing maternally inherited mitochondrial DNA (mtDNA) divergence. This study analyzes mtDNA variation in Peromyscus species, revealing patterns relevant to speciation demography.

Area of Science:

  • Evolutionary Biology
  • Molecular Evolution
  • Population Genetics

Background:

  • Understanding the relationship between speciation and the evolution of uniparentally transmitted traits, such as mitochondrial DNA (mtDNA), is crucial in evolutionary biology.
  • Asexual transmission of characters can exhibit unique divergence patterns influenced by speciation events in bisexual species.

Purpose of the Study:

  • To investigate the significance of biological speciation on the magnitude and pattern of divergence in asexually transmitted characters within bisexual species.
  • To analyze mitochondrial DNA (mtDNA) restriction site variability in Peromyscus species to infer matriarchal phylogenies and their relationship to speciation.

Main Methods:

  • Restriction endonuclease site variability analysis of maternally transmitted mitochondrial DNA (mtDNA) from 82 samples of Peromyscus polionotus and P. leucopus.

  • Estimation of matriarchal phylogenies using clustering algorithms and qualitative Wagner procedures for phenogram and parsimony network generation.

    • Main Results:

    • Observed mtDNA variation is attributed to base substitutions affecting recognition sites.
    • Intraspecific mtDNA sequence divergence in P. polionotus (approx. 2%) is comparable to P. maniculatus, while P. leucopus shows greater divergence (approx. 4%).
    • Empirical results for P. maniculatus and P. polionotus mtDNA align with a model where one species is paraphyletic with respect to a monophyletic sister species.

    Conclusions:

    • The distribution patterns of mtDNA sequence variation within and among species are relevant to understanding speciation demographies.
    • Theoretical models illustrate conceivable relationships between mtDNA differentiation and speciation, including monophyletic, non-monophyletic, and paraphyletic species scenarios.
    • Findings suggest that speciation processes can lead to complex patterns of mtDNA variation, challenging simple interpretations of uniparental inheritance in evolutionary studies.
