The difference between the brightness of the exterior and central part of a Timema's body ('brightness contrast') is under strong divergent selection between hosts (Ceanothus versus Adenostoma) [71], and the degree of divergence in this trait thus represents one measure of the degree of divergent host-plant adaptation.
A deterministic two-locus two-deme model is employed to explore the effects of migration, the degree of divergent selection, and the genetic architecture, i.e., the recombination rate and ratio of locus effects, on the maintenance of genetic variation.
This could indicate a degree of divergent evolution of this cyclophilin to fulfil the needs of both Group G and Group H within its parent fungi.
Correlating both Figures 5A and 5B, we can conclude that abundant functional families undergo higher degree of divergent evolution but, they are less frequent.
The decaying curve depicts the relationship between the number of functional families and degree of divergent evolution for a family which is best approximated by a power-law (which means few functional families undergo high degree of divergent evolution), where Y ~ X-1.7, with R2 = 0.95.
McCarthy et al. [ 24] demonstrated that despite some congruence of opinion between GPs and PNs, there remained a degree of divergent opinion regarding the nursing roles, with GPs underestimating the PN scope of practice.
Group II contain IRI-like genes with high degree of divergent predicted peptide structure, i.e. putative peptides with strongly reduced and completely lost IRI-domain (TaC9 and TaC11) as well as predicted peptides with large IRI-domains.
If, as we are proposing, this organization is tightly related to axon collateral branching, then a corollary suggestion is that a high degree of divergent branching is a feature specific to association cortex.
In other words, if a functional family finds remote homologs in 8 nodes, it has gone through the highest degree of divergent evolution as measured by the sequence identity among its members.
Thus, like domain combinations, domain evolution is also showing power-law behavior, which means few functional families undergo high degree of divergent evolution whereas most of the functional families generally evolve maintaining sequence identity detectable within the range of profile-sequence comparison method.
