Sentence examples for shallow levels of divergence from inspiring English sources
Given the relatively shallow levels of divergence across these lineages in both the mitochondrial and nuclear data sets and the general lack of geographical concordance throughout the M. torreya clade, it is our opinion that such a hierarchical driven recalibration of species boundaries would be flawed.
The present results showed shallow levels of divergence among the members of the P. imbricata/ fucata/ radiata species complex, comparable to the levels of divergence of conspecific exemplars of other Pinctada species.
They pointed out the possibility of making Type I errors (overlooking significant correlations) by using such a conservative method at shallow levels of divergence, but noted that more studies at this scale are warranted.
A strict molecular clock was assumed given the shallow levels of divergence, with a mitochondrial mean rate of 1.52%% divergence per million years, with a standard deviation of 0.5 % divergence, based on mtDNA calibrations from other squamates [ 69].
We, therefore, developed an automated supermatrix procedure to infer phylogenies for a large sample of vertebrate diversity targeted at these shallow levels of divergence (see Methods section and Additional File 1).
Especially at this shallow level of divergence, it is likely that multiple processes such as demography and incomplete lineage sorting influence the gene genealogies and the implementation of a method that properly accommodates this variation, rather than a concatenation approach, becomes especially relevant [ 89, 90] and references therein.
Phylogenetic trees were not reconstructed for β-globin given shallow levels of genetic variation.
Further, these recommendations apply to studies at relatively shallow levels of diversity (generally at the family level and below).
Levels of divergence at these loci exceed observed levels of divergence observed at a mitochondrial gene region at Easter Island.
Possibly, the level of divergence among Th.
The background level of divergence, Db, is the average level of divergence across all windows.
