单词 cladogenesis
释义

Definition of cladogenesis in English:

cladogenesis

noun ˈkladə(ʊ)dʒɛnɪsɪsˌkleɪdə(ʊ)ˈdʒɛnɪsɪsˌklādōˈjenəsəsˌkladəˈjenəsəs
mass nounBiology
  • The formation of a new group of organisms or higher taxon by evolutionary divergence from an ancestral form.

    Example sentencesExamples
    • This process of organic transformation includes anagenesis as well as cladogenesis.
    • However, there is little consensus as to how specialization affects diversity: does it act to increase or decrease rates of cladogenesis?
    • However, our results appeared sensitive to the prior model of cladogenesis, although the oldest estimates were obtained under a suboptimal model.
    • Parallel cladogenesis between host and pathogens would be indicative of ancient coevolution, a reciprocal process in which characteristics of one organism evolve in response to specific characteristics of another.
    • In other words, the earliest species to diverge have undergone the most prolonged coevolution with their particular array of potential hosts and accordingly have become more specialized even in the absence of cladogenesis.

Derivatives

  • cladogenetic

  • adjectiveˌkleɪdə(ʊ)dʒəˈnɛtɪkˌkladə(ʊ)dʒəˈnɛtɪk
    Biology
    • Another aspect of the rate of evolution involves the amount of morphological change that occurs at speciation or cladogenetic events.
      Example sentencesExamples
      • Philippe and Adoutte suggested that a big bang occurred at the base of eukaryotes and that the major cladogenetic events in eukaryotic evolution occurred in quick succession.
      • As pointed out by a number of authors, the evolution of bilaterian body plans must postdate the cladogenetic separation of lineages leading to these animal phyla.
      • Phylogenetic systematics plays down the role of ancestors and depicts the accumulation of character changes at the inferred cladogenetic events.
      • Although molecular dating of cladogenetic events is possible, no molecular method has been described to date the acquisition of various tissues.
