Under this model, each of the biological transitions is, indeed, a transition in a more specific, technical sense, i.e., a switch between two phases of evolution, a phase of rapid evolution (inflation) characterized by rampant exchange and recombination of genetic material, followed by congealing into a relatively slow phase governed by the tree pattern.
While the experimental technologies and analysis methods are in a phase of rapid evolution, recent studies share common analysis tasks.
A similar evolutionary dynamic is observed for the heterodimerisation interface, where several positions experienced positive selection during the emergence of Mecopterida, followed by a phase of constrained evolution.
In conclusion, the dimerisation interface of USP has experienced modifications of selective constraints during the emergence of Mecopterida, followed by a phase of constrained evolution.
Similarly, several positions of the heterodimerisation interface experienced positive selection during the emergence of Mecopterida, rapidly followed by a phase of constrained evolution.
Hence, newly established introns may pass through a phase of early evolution in which they are more susceptible to length mutation of this variety.
These independently evolved lineages, characterized for some phenotypic traits and for their full-genome consensus sequence, constituted an ideal material to investigate historical contingency: we have been able to ask if their initial characteristics affected their phenotype and genotype after a new phase of evolution in a common host.
If the supergroups of eukaryotes indeed diverged in a rapid succession during an explosive phase of evolution, the problem of estimating the age of the Last Eukaryotic Common Ancestor (LECA) assumes a special importance.
By making it easier for family members to eat different meals at different times, microwaves threaten to undo the cooking revolution, he says, and to return us "to a presocial phase of evolution".
Taking into account oil depletion, increasing population, and increasing energy demand, electrical power generation has entered into a new phase of evolution, which can be characterized mainly by increasing concerns about climate change, by a transition from a hydrocarbon-based economy, and by an efficient utilization of energy.
