The polytheistic cults of Greece and Rome didn't die out in an incremental process of evolutionary decline; they were stamped out when the emperor Constantine converted to Christianity.
While hardly taxing, the whodunit plot is funny and twisted, and it gives Madeline plenty of opportunities to air her caustic views on the evolutionary decline of her social class.
That evolutionary decline kicked into fast-forward in July, when De Beers axed some 35 sightholders exclusive buyers of its rough diamonds many of them based in the district.
Therefore, owing to the disparity between the sexes in the magnitude of S (with S♂ > S♀), we suspect that the evolutionary decline in body size will usually be much greater than that predicted by Hutchings and Rowe, as their model assumed no sex differences.
This in turn indicates that the evolutionary rate declines dramatically within 100 kyr.
The rate of evolutionary change declined for all three traits (Table 2) over the course of the experiment, with statistically significant evolution over the first 500 and second 500 generations, but with a rate of change roughly two to ten times greater during generations 0 500 than during generations 501 1000.
However, it is still largely unclear to what extent it is possible to quantify and predict the chance of evolutionary rescue in declining populations.
Further efforts are required to elucidate the indirect evolutionary effects of declining population abundances, both in salmonids and in other anthropogenically challenged organisms.
The selection strength estimated from the fits declines with evolutionary divergence while staying well outside the neutral regime.
The first observation is that the proportion of genes that show ω > 1, a traditional threshold for interpreting positive selection, strongly declines with evolutionary distance (logistic regression, P < 0.001, null deviance: 5284.15, residual deviance: 294.2).
