Using measures of diversity, they also demonstrated that "the mutation rate governs a transition between two qualitatively different phases of evolutionary dynamics", namely a more ordered state characterized by long periods of stasis for low mutation rates, and highly disordered dynamics where "the gene pool tends to be a continually changing plethora" of strategies at high mutation rates [19].
Symbiogenic models posit that eukaryotes arose via a symbiotic association of divergent prokaryotic cells, with symbiosis (and gene transfer from endosymbiont to host in some formulations) forging the prokaryote-to-eukaryote transition, with phases of evolutionary innovation marked by distinctly non-gradualist characteristics.
Symeon's mystical theology is a distinct phase of an evolutionary process in Greek spirituality that began in the late 2nd century.
In fact, the differing design of skulls, teeth, wings, and feet indicate that, even at this early phase of their evolutionary history, birds had specialized into a variety of ecological niches, including seed-feeders, insect-feeders, fish-eaters, and meat-eaters (Chiappe 2007).
Many of the complex traits that distinguish the organisation and biology of multicellular animals originated during the early phase of their evolutionary history.
He is interested in the early phases of primate evolutionary history, and how anatomical diversity reflects an evolutionary history of selective pressures more generally.
The major post-LUCA phases of the evolutionary history of the β-GF fold saw two major spurts of innovation.
This correlation between age and rate may have a crucial biological interest, because it is consistent with a model of origin of novel genes that assumes that these genes arose through a gene duplication and an initial phase of exceptionally high evolutionary rates.
The multiple-level landscape model is introduced following the description of punctuated cancer evolution, the relationship of evolutionary phase transition and genome instability, the importance of fuzzy inheritance in heterogeneity, and the mechanism of cancer as an emergent system with different genomes.
It has been convincingly argued that conserved indels result less likely than e.g. point mutations from independent mutational events and provide useful milestones for the identification of evolutionary phases [ 45].
