Therefore, one might expect stronger selection by pathogen-driven selective forces (heterozygote advantage, frequency dependent selection and fluctuating selection [26]) in our population than in populations with a lower pathogen load.
One might expect stabilizing selection to be observed in at least some studies if body size had reached an evolutionary equilibrium, so consistent selection for larger size seems paradoxical.
"Under such conditions," he writes, "one might expect natural selection to favor rapid acquisition of a fully functional alarm call system".
We might expect natural selection to favor individual moths in this new population whose appearance better matches the background, as they will avoid predation.
Yet, given the magnitude of the mortality reported for some species [4], we might expect natural selection to favor individuals that either learn to avoid cars or that have other traits making them less likely to collide with vehicles.
It's not, as you might expect, a selection of tracks that lean towards the dancefloor side of noise but a representation of the whole spectrum.
While one might expect positive selection to eradicate risk-associated mutations and favor protective variants, like we find for CD (Table 1), we also surprisingly find the strongest selection working in favor of risk-associated alleles in both T1D and RA (Fig. 1b and Table 1).
Thus, we might expect natural selection to fine-tune thermal norms of reaction, such that higher temperatures induce less of an increase in hatchling metabolic (and thus, heart beat) rates in free-living animals than was the case prior to hatching.
One might expect natural selection in favor of such regulation.
