Natural icing testing is a unique part of the test program required to certify aircraft to operate in all weathers. Over the last three years employees at the Bombardier Flight Center (BFTC) in Wichita, have conducted natural icing testing during the development and certification of two clean-...
To further test selection, we simulated neutral evolution along the yeast tree 1000 times under a Brownian motion model with the observed mutational covariance matrix M used as the mutational input, generating 1,000 simulated datasets. Before the simulation, we confirmed that the sampling error of ...
Testing natural selection vs. genetic drift in phenotypic evolution using quantitative trait... Provides information on a study which used trait locus data to analyze natural selection and random genetic drift. Discussion on the usage of quantitative ... Orr,H.,Allen - 《Genetics》 被引量: 163...
Theory shows how sexual selection can exaggerate male traits beyond naturally selected optima and also how natural selection can ultimately halt trait elaboration. Empirical evidence supports this theory, but to our knowledge, there have been no experimental evolution studies directly testing this logic,...
Natural selection constrains neutral diversity across a wide range of species. The neutral theory of molecular evolution predicts that the amount of neutral polymorphisms within a species will increase proportionally with the census p... Russell,B,Corbett-Detig,... - 《Plos Biology》 被引量: 148...

CAN INTRASPECIFIC COMPETITION DRIVE DISRUPTIVE SELECTION? AN EXPERIMENTAL TEST IN NATURAL POPULATIONS OF STICKLEBACKS 鈥Theory suggests that frequency-dependent resource competition will disproportionately impact the most common phenotypes in a population. The resulting d... DI Bolnick - 《Evolution》 被引...
Firstly, natural selection may be a dominant force in AI development. Competition and power-seeking may dampen the effects of safety measures, leaving more “natural” forces to select the surviving AI agents. Secondly, evolution by natural selection tends to give rise to selfish behavior. While ...
THE GOODNESS–OF–FIT TEST FOR DETECTING NATURAL SELECTION IN RANDOM MATING POPULATIONS The physiological activity of complete series of mono- and di-substituted chloro-and methyl-phenoxyacetic and benzoic acids have been investigated using the wheat cylinder, pea segment and pea curvature tests. In ...
Signatures of natural selection are confounded by population history and variation in local recombination rates. Demographic processes should affect all loci in a similar way, whereas the effects of selection should be restricted to specific loci. ...
