GOEvol VI - #Sensation @GOEEvolution 2018

Goevol 2018

The perception of environmental stimuli, their processing and integration is essential for any organism. Apart from the more familiar senses like hearing, seeing or tasting, there are sensory tasks performed by highly specialized animals, such as echolocation in bats or the perception of polarized light in grasshoppers. Sensory processing consequently also differs strongly between species. However, at the same time there are astonishing similarities between sensory modalities of phylogenetically distant animal groups, such as the shared cellular structure of light-sensitive organs or the genetic control and developmental origin of sensory cells. With methodological innovation, more and more species can be used for detailed analyses, which further expand the understanding of the evolution of sensation.

Because of the diversity of research and various methodologies in multiple (emerging) model organisms in the field of evolution of sensation we want to bring together scientists from a broad range of fields to reveal commonalities across disciplines.

Following the GOEvol tradition, we aim for an interdisciplinary symposium with an informal atmosphere with plenty of possibilities for social networking. If you enjoy small interactive meetings and the topic suits you, come along!

Zwei Sofja Kovalevskaja-Preisträger für die Universität Göttingen

Preis Gewonnen

Der Entwicklungsbiologe Günesdogan wird in Göttingen Prozesse bei der Vererbung untersuchen. Die DNS im Zellkern ist der Träger der Erbinformation. Jedoch kann die Nutzung dieser Information auf unterschiedliche Weise erfolgen, denn bei der Verpackung der DNS werden sogenannte Histon-Proteine genutzt, die zusätzliche vererbbare Informationen speichern – ein Prozess, der Epigenetik genannt wird. So werden beispielsweise eineiige Zwillinge mit den gleichen Genen geboren, können sich im Laufe ihres Lebens aber unterschiedlich entwickeln. Günesdogan untersucht die dabei wirkenden Mechanismen ausgehend von den Urkeimbahnzellen, aus denen Spermien und Eizellen entstehen. In Göttingen wird er am Johann-Friedrich-Blumenbach-Institut für Zoologie und Anthropologie forschen. Gastgeber ist Prof. Dr. Ernst A. Wimmer.


Disrupting housefly gene reverses sex

Musca Stubenfliege

Science AAAS wrote in their newest issue: "Sex comes in many forms, even when considered at the molecular level. In different animals, the chromosomes and specific genes that function in sex determination vary widely. As a case in point, the familiar housefly displays a highly variable sex determination system. In this animal, the male determiner (M-factor) instructs male development when it is active, but female development results when it is inactive. Sharma et al. now identify the housefly M-factor, which arose via the co-option of existing genes, gene duplication, and neofunctionalization. The findings elucidate the remarkable diversity in sex-determining pathways and the forces that drive this diversity."
