But as my conclusions have lately been much misrepresented, and it has been stated that I attribute the modification of species exclusively to natural selection, I may be permitted to remark that in the first edition of this work, and subsequently, I placed in a most conspicuous position—name...
Rather, natural selection occurs as species change to adapt to life: how efficient a tree is at dispersing seeds; a fish's ability to find a safe spawning ground before laying her eggs; the skill with which a bird retrieves seeds from the deep, fragrant cup of a flower; a bacterium's ...
[136] highlighted how social network-based clusters can capture homophily, as well as the prospect that a network-based attribute method could not only capture homophily but also be utilized instead of demographic traits to assess user behavior similarity, maintaining user privacy. For clustering ...
Instead of selection, Wright proposed in his shifting balance theory that the basis for an adaptive complex of genes will first arise by chance (after the constituent alleles at different loci have not only arisen by chance, but have also spread by random genetic drift in a given subpopulation)...
Since then, strong selection has been an accepted part of the peppered moth story. Just how strong is more difficult to settle, as the change was from one extreme frequency to the other, but one of Haldane's calculations suggested an advantage as great as 30 per cent. The phenomenon of ...
barley, Hordeum vulgare L.) worldwide that offer beneficial traits for plant breeding. The phenotypic variation within-species caused by spontaneously natural genetic mutations that maintained in nature by evolutionary, artificial and natural selection processes [1]. Natural variation brought great ...
The two-stage selection method employed metabolic intensity for early estimation of IgG production, enabling the elimination of clones showing low productivity. Implementing the new method in practice leads to reduced time and cost during the process of establishing stable cell lines.With training ...
Identification of candidate genes underlying natural phenotypic variation for oenological traits.

Amyloidogenicity disparities in 6aJL2, under these experimental conditions, are suggested to arise from the engagement of multiple aggregation routes, involving unfolded intermediates and the genesis of oligomers.Mouse embryo three-dimensional (3D) imaging data, a substantial collection generated by the ...
Such variability in genetically encoded traits is a prerequisite for natural or artificial selection to occur, and is widespread. But because neural crest cells are involved in so many other developmental events, selection for reduced neural crest activity (“mild neurocristopathy”, as they called ...
