A role for genetic accommodation in evolution?

Braendle, Christian ; Flatt, Thomas

In: BioEssays, 2006, no. 28, p. 868-873

Whether evolutionary change can occur by genetic assimilation, or more generally by genetic accommodation, remains controversial. Here we examine some of the experimental evidence for both phenomena. Several experiments in Drosophila suggest that assimilation is possible, and a new paper1 shows that a color polyphenism in the tobacco hornworm, Manduca sexta, can evolve by genetic ...

Evolutionary origin of synapses and neurons – Bridging the gap

Burkhardt, Pawel ; Sprecher, Simon G.

In: BioEssays, 2017/39/10/n/a-n/a

The evolutionary origin of synapses and neurons is an enigmatic subject that inspires much debate. Non-bilaterian metazoans, both with and without neurons and their closest relatives already contain many components of the molecular toolkits for synapse functions. The origin of these components and their assembly into ancient synaptic signaling machineries are particularly important in light...

Sur les traces de l’évolution de la catégorie orange : Une étude sémasiologique comparative du français et de l’allemand = Evolution of the orange color category in french and german

Desgrippes, Magalie ; Berthele, Raphael (Dir.)

Mémoire de master : Université de Fribourg, 2011.

Anthropologists, psychologists and linguists generally consider that each language has a fairly uniform color system and that the systems of most European languages are all at the end of the same evolution and too close to each other to be of interest. Starting from the simple observation that the traffic light color called orange in French is called gelb (yellow) in German, this research...
