Fly palaeo-evo-devo: immature stages of bibionomorphan dipterans in Baltic and Bitterfeld amber

New Aderidae (Coleoptera: Tenebrionoidea) from Baltic and Bitterfeld amber.

Nine extinct species and one genus of aderid beetles (Coleoptera: Tenebrionoidea: Aderidae) are described from Baltic and Bitterfeld amber from Germany, Russia (Kaliningrad), Poland, and Denmark. These new species include: Escalerosia igori sp. nov., Picemelinus irinae sp. nov., Vanonus ulmerigicus sp. nov., Vanonus aestiorum sp. nov., Cnopus kraxtepellenensis sp. nov., and four species from th...

Worm Palaeo-Evo-Devo – The ontogeny of Ottoia prolifica from the Bur- gess Shale

Ottoia prolifica Walcott, 1911 is a 500 million years old fossil cycloneuralian worm from the Burgess Shale, Canada, British Columbia. We report newly observed details of the morphology and ontogeny of this species. Previously unknown details could be observed by applying crossedpolarized light. This approach revealed that the tail end is equipped with six hook-shaped spines and that the scalid...

The evo-devo comet.

In his inspiring book Ontogeny and Phylogeny (1977), the late Stephen J. Gould explained why develop mental biology and evolution, two essential domains of the life sciences, had diverged during the course of the twentieth century; both disciplines had to reach independently a platform of mutual understanding, a theoretical framework wherein concepts are understood and accepted by both parties....

Evo-devo discovers morphology

constructive points. A critical examination is made of FA’s strength and weaknesses in comparison with other biomarkers, and ways to improve FA as a bio-indicator are suggested. As a whole, Developmental Instability is a mature and balanced compilation of an important subject in biology, which is, after all, about half a century old. Michal Polak has managed to combine excellent contributions o...
