  • Ecological
  • The concepts of kin selection theory now provide powerful methods for analyzing models of evolution of social behaviors, including not only reproductive self-sacrifice in social insects but also the occurrence of conflicts within such societies, and more broadly any ecological interaction that includes cooperative or competitive interactions between individuals. (oxfordbibliographies.com)
  • Numerous studies in the ecological and evolutionary literature have estimated the magnitude of natural selection. (ucsb.edu)

  • organisms
  • This combination of spatial selection and spatial inheritance acts to bias the distribution of organisms toward suitable sites and thereby increase mean fitness (i.e., per capita population increase). (siu.edu)
  • This method will be applied to meta-analyses examining the overall influence of selection on demographic components of fitness in a broad variety of organisms. (ucsb.edu)
  • framework
  • The feature selection method is evaluated by using three well-known classifiers (SVM, Logistic Regression, and Naive Bayes) implemented within the Spark framework to address big data problems. (hindawi.com)
  • In the experiments, datasets up to 67 millions of instances and up to 2000 attributes have been managed, showing that this is a suitable framework to perform evolutionary feature selection, improving both the classification accuracy and its runtime when dealing with big data problems.

  • amino acid changes
  • Application of site models, which estimate overall selection pressures on individual codons throughout the phylogeny, showed that the amino acid changes observed were either neutral or under negative selection. (biomedcentral.com)
  • Neutral amino acid changes were identified in the forkhead domain of the FoxA, FoxD and FoxP clusters while positive selection was identified in the forkhead domain of the Protostomia lineage of the FoxA cluster. (biomedcentral.com)
  • Overall we found that after gene duplication of forkhead family members, rapid differentiation and subsequent fixation of amino acid changes through negative selection has occurred. (biomedcentral.com)
  • However, this test is heavily conservative as proteins are generally under negative selection against amino acid changes that may affect protein function. (biomedcentral.com)
  • translational efficiency
  • It has previously been shown that both selection acting to increase codon translational efficiency and selection acting to decrease codon biosynthetic cost contribute to differences in codon bias. (biomedcentral.com)
  • Instead, we show that transfer RNA gene copy number alters the cost-efficiency trade-off of synonymous codons such that, for many species, selection acting on transcript biosynthetic cost and translational efficiency act in opposition. (biomedcentral.com)
  • natural
  • We often hear about new 'genome sequences,' commercial kits that can tell you about your ancestry (including pre-human) from your DNA or disease predispositions, debates about the truth of evolution, why animals behave the way they do, and how people found 'genetic evidence for natural selection. (coursera.org)
  • The mate selection plays a key role in natural evolution process. (aimsciences.org)
  • Natural selection by way of effects on genetic relatives has been named kin selection , and can thus occur whenever relatives preferentially interact together, in family-structured or spatially structured populations. (oxfordbibliographies.com)
  • How natural selection responds to the female deaths and thereby the unequal fitness of the sexes has rarely been addressed. (hindawi.com)
  • We shed light on this issue and provide evidence, which suggests that additional gains of fitness by males due to their longevity and continued mating may provide one explanation as to why the loss of female fitness may be "invisible" (effectively neutral) to natural selection. (hindawi.com)
  • This project has clear ramifications for incorporating evolutionary considerations in the management and conservation of living natural resources. (ucsb.edu)
  • mechanism
  • Selective pressures acting among populations may differ from those acting within, with directional selection implicated in driving divergence among populations and balancing selection as a possible mechanism for producing variability among males. (biomedcentral.com)
  • females
  • One of the things that Prum proposes, toward the end of The Evolution of Beauty, is that homosexuality in humans also evolved as a result of females seeking to exercise sexual autonomy-their evolutionary "need" to have free mate choice. (wordpress.com)
  • subsets
  • We now know that we can represent possible attribute subsets with bit vectors.We can represent the selection of all attributes of a data set which consists of 10 attributes in total such as (1 1 1 1 1 1 1 1 1 1). (kdnuggets.com)

  • We also show that reasonably small differences in the length of intermediate "neutral" sequences embedded in a region under selection increase the effectiveness of selection on the adjacent selected sequences. (genetics.org)
