Sexual size dimorphism and sexual selection in artiodactyls
(Oxford Univ Press Inc, 2020-06)
Sexual size dimorphism is biased toward males in most mammalian species. The most common explanation is precopulatory intramale sexual selection. Large males win fights and mate more frequently. In artiodactyls, previous ...

(Universidad Nacional de QuilmesUniversidad Nacional de Tres de Febrero, 2016-04-01)
Esta contribución se aproxima al desarrollo transtemporal de las teorías científicas mediante un estudio de caso particular: el modo en que la modificación diacrónica del conjunto de aplicaciones pretendidas de la teoría ...
Pollinator-mediated selection in a specialized pollination system: matches and mismatches among populations
(Wiley Blackwell Publishing, Inc, 2010-09)
Most studies on pollinator-mediated selection have been performed in generalized rather than specialized pollination systems. This situation has impeded evaluation of the extent to which selection acts on attraction or ...
Cultural adaptations: Is it conceptually coherent to apply natural selection to cultural evolution?
(Archaeopress, 2016)
Critics of Darwinian approaches to the study of the evolution of human and social behavior often express their dissent claiming that cultural evolution is Lamarckian. By this they mean two things. First, that contrary to ...
Artificial selection of maize as a bridging case to teach natural selection: a simulation proposal
(Inst Biology, 2019-12)
In this paper, we present a simulation of artificial selection of maize thatcan be used as a bridging case for the subsequent introduction of naturalselection in school. The proposed simulation takes up essential ...
Disentangling Signatures of Selection Before and After European Colonization in Latin Americans
(Oxford University Press, 2022)
Throughout human evolutionary history, large-scale migrations have led to intermixing (i.e., admixture) between previously separated human groups. Although classical and recent work have shown that studying admixture can ...

(Sociedad de Biología de Chile, 2005-12)
It has been argued that the study of natural selection and quantitative genetics should have a central role in evolutionary thinking and undergraduate teaching in Chile. Extensive operational use of the concept of natural ...
