If yes, can you name an instance where magic influenced something? A link to a source, if possible, would be helpful.
Thank you!
Hello

Trends in Ecology & Evolution, Volume 26, Issue 8, 389-397, 18 May 2011 has an abstract.
Magic traits in speciation: magic but not rare? that was of interest to me. The authors are Maria R. Servedio, G. Sander Van Doorn, Michael Kopp, Alicia M. Frame, Patrik Nosil.

“What is a magic trait? Even though magic traits are often studied purely at the phenotypic level, a precise definition requires reference to the underlying genetics. This is because magic traits are encoded by ‘magic genes’, that is, genes subject to divergent selection that also pleiotropically affect reproductive isolation. The fundamental requirement of pleiotropy guarantees an association between divergent selection and non-random mating that cannot be broken by recombination; this is what renders magic traits effective in driving speciation with gene flow in theoretical models (Box 1). Usually, one thinks of magic-trait genes as controlling a single trait; many magic traits identified phenotypically will undoubtedly fall into this category. However, this need not necessarily be the case. A complex of two identifiable phenotypic traits, one under divergent selection and one involved in non-random mating, can be considered magic if the two component traits share a common genetic basis. We collectively refer to both these cases as a ‘magic trait’ (note that in the latter case, if the traits are polygenic then pleiotropy can be partial, rendering the trait complex partly magic).” p.g.

I’m interested in science and this is a scientific article. I’m happy to present it because I support science.
