In other words, any domain that contained part of this line, the divergence would be zero along that line.
Given this rationale, the observation of even a few genes exhibiting significantly elevated divergence would be surprising without an a priori hypothesis providing an explanation for diverged genes in a conserved pathway.
And whether it's designed to look this way or not, the implication is that a lot of policy divergence would be rendered pointless.
But the rate of fatal gun violence in California has fallen by about 20% Figuring out what California policies or conditions have contributed to this divergence would be invaluable for federal and state lawmakers contemplating new legislation".
One prediction of this co-evolution model is that the amount of sequence divergence would be inversely related to how effective the mechanisms of the species-specific transcription hypothesis operate and this appears to be the case.
As the feeding and anti-predation adaptation hypotheses do not contradict one another (i.e., similar morphological divergence would be predicted by both hypotheses), the synergetic effects of natural selection might have caused the observed body shape/color differences.
Perhaps a good model would be a hybrid that included both molecular and morphological criteria, in which molecular divergence would be the metric, but the cutoff between species would be guided by their degree of structural similarity, host range, or interbreeding when such data are available.
If, as introduced above, θ is reduced in LR loci due to strong regional Ne-reducing effects of selection, both in extant D. simulans and in the ancestral population, then if g exceeds 1, divergence would be disproportionately greater in HR genes than would be expected when g is 1.
Given the range of the data surveyed, some divergence would be expected.
We also expected that morphological divergence would be further enhanced by exposure to different predators.
However, a single duplication that predates the mammalian divergence would be a more parsimonious explanation.
