All characters and trait systems in an organism share a common evolutionary history that can be estimated using phylogenetic methods. However, differential rates of change and the evolutionary mechanisms driving those rates result in pervasive phylogenetic conflict. These drivers need to be uncovered because mismatches between evolutionary processes and phylogenetic models can lead to high conf...

Historically, characters from early animal development have been a potentially rich source of phylogenetic information, but many traits associated with the gametes and larval stages of animals with complex life cycles are widely suspected to have evolved frequent convergent similarities. Such convergences will confound true phylogenetic relationships. We compared phylogenetic inferences based o...

the aim of this paper is to classify the finite simple groups with the number of zeros at most seven greater than the number of nonlinear irreducible characters in the character tables. we find that they are exactly a$_{5}$, l$_{2}(7)$ and a$_{6}$.

Artikkelissa selvitetään, miten tietäjä-hahmot esitetään 1800-luvun lopulla ja 1900-luvun alussa ruotsinkieliseltä Pohjanmaalta kerätyssä folkloristisessa aineistossa. Aineistoa lähestytään kvalitatiivisen tekstianalyysin kautta. Esitän, että pohjanmaalaiset ruotsinkieliset uskomustarinat tietäjistä pohjautuvat vakiintuneisiin vernakulaareihin uskomuksiin, jotka ovat samankaltaisia länsieuroopp...
