As it has often been pointed out, however, there is nothing in the concept of natural selection that suggests that competition is the most successful strategy for "survival of the fittest." Darwin asserted in The Origin of Species that the qualities he was describing should be more as ...
Wallace's discovery of the principle of natural selection. In both of these examples the meaning of questions, especially of well-chosen why-questions, of strategic principles, and of highly structured background knowledge come to the fore. Good questions frequent those who have orderly expectations...
New Perspectives on English Sound Patterns: "Natural" and "Unnatural" in Evolutionary Phonology. Principles of Evolutionary Phonology are applied to a selection of sound changes and stable sound patterns in varieties of English. These are divided into ...

NQ contains 307,372 training examples, 7,830 examples for development, and we withold a further 7,842 examples for testing. In the paper, we demonstrate a human upper bound of 87% F1 on the long answer selection task, and 76% on the short answer selection task. ...

The average rate of TE transposition in nature may thus depend on the frequency of permissive alleles, which is a function of the rate of mutation from restrictive to permissive alleles, the mechanism and the strength of selection opposing TE multiplication, and population size. Thus, evolution ...
