  • What is Speciation, How Does It Occur, and Why Is It Important for . . .
    Abstract Speciation provides a framework for classifying biodiversity on Earth and is a central concept in evolutionary biology To help undergraduate students learn about speciation, we designed a student-centered lesson that uses active-learning techniques (e g , clicker questions, small group work, and whole class discussion) and compares multiple species concepts (morphological, biological
  • untitled [biology-assets. anu. edu. au]
    Indirect support for this hypothesis has been provided by comparative analyses of various taxonomic groups that have found that signatures of sexual selection are correlated with increased speciosity (reviewed in Panhuis et al 2001; Coyne Orr 2004; Ritchie 2007)

    However, Foley (1991), using models based on primate diversity in rela-tion to geographical range size and evolutionary rates, proposed levels of speciosity that match the fossil record well, and
  • The Evolutionary Genetics of Speciation - JSTOR
    The last decade has brought renewed interest in the genetics of speciation, yielding a number of new models and empirical results Defining speciation as 'the origin of reproductive isolation between two taxa', we review recent theoretical studies and relevant data, emphasizing the regular patterns seen among genetic analyses Finally, we point out some important and tractable questions about
  • The Role of Genomics in Evolutionary Biology: Understanding Adaptation . . .
    Genomics has significantly advanced our understanding of evolutionary biology by providing a detailed genetic perspective on adaptation and speciation Here’s how genomics contributes to these key evolutionary processes genomic studies reveal the specific genetic changes that enable organisms to adapt to their environments By sequencing the genomes of populations subjected to different
  • How phenotypic matching based on neutral mating cues enables speciation . . .
    Abstract Maynard Smith's (American Naturalist, 1966, 100, 637) suggestion that in some cases a prerequisite for speciation is the existence of local ecological adaptations has not received much attention to date Here, we test the hypothesis using a model like that of Maynard Smith but differing in the way animals disperse between niches In previous studies, males disperse randomly between
  • Biodiversity measurements are of great value to conservationists
    significantly above oceanic keynotes and corresponds to the speciosity measurement in biodiversity Sound pressure variability is comprised of two measurements: the abundance of sound signals, which corresponds to population estimation, and intensity averages, which correspond to habitat variability Combined with qualitative analyses,
  • The evolutionary genetics of speciation - Integrative Biology
    Because speciation is complete when reproductive isola-tion stops gene £ow in sympatry, the `genetics of speciation' properly involves the study of only those isolating mechanisms evolving up to that moment The further evolution of reproductive isolation, although inter-esting, is irrelevant to speciation This point is widely recognized but understandably often ignored in practice If
