Definition of cladogenesis in English:
noun[mass noun] Biology
The formation of a new group of organisms or higher taxon by evolutionary divergence from an ancestral form.
- This process of organic transformation includes anagenesis as well as cladogenesis.
- 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.
- Example sentences
- 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.
- Another aspect of the rate of evolution involves the amount of morphological change that occurs at speciation or cladogenetic events.
- 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.
