Species evolution is often depicted as linear, neatly separated branches of a tree, an oversimplification that fails to capture the true complexity of evolutionary history. This is especially true for human evolution, where the prevailing belief has been that the modern human population that emerged from Africa was […]

Last week a long journey finally came to a result. If you remember, we were lucky to secure a Peder Sather grant to secure a collaboration between Rosemarie Gillespie’s lab and ours. Just a reminder from the last blog; Peder Sather was a banker and founder of the […]

Today, I would like to present to the paper by Tianzhu Xiong and James Mallet about “On the impermanence of species: The collapse of genetic incompatibilities in hybridizing populations” in Evolution. The topic of the paper is not my area of research, which are deep level phylogeny, evolutionary […]

Published in October, startling results of natural selection in humans indicates certain immunity genes may have helped people survive the Black Death of the 1346-1350. Caused by the bacterium Yersinia pestis, bubonic plague has swept across the globe (as pandemics) numerous times over the centuries, resulting in untold […]

The bowhead whales (Balaena mysticetus) in the East Greenland Sea, the Svalbard region and the Barents Sea (referred to as the East Greenland-Svalbard-Barents Sea (EGSB) stock) has been intensively studied for many years by members of the FEZ group. The stock is classified as Endangered in the International Union of […]

Species of the genus Stygocapitella belong to the ringed worms, also known as Annelida. Annelids are worms like earthworms, lugworm or christmas tree worms, but also leeches or very tiny worms living in the spaces between the sand grains, called the interstitium. Such an interstitial group of worms […]

During his PhD Jose was interested in the evolution of the cryptic species complexes in the annelid genus Stygocapitella, which occurs at sandy beaches around the world. Part of his thesis also comprised population-genomic studies to understand the underlying genomic background of morphological stasis. During the phylogenomic studies […]

Cryptic species have for long time been considered as purely a taxonomical challenge. However, in the last decade it has been shown that their recognition has also consequences for several other biological disciplines. Recently, their importance for understanding certain evolutionary processes has been highlighted. Most prominent among these […]

Our calendar is coming to its close and at the second-to-last day it features two Master projects, which started this year working with annelids, which are both completely computer-based making use of the SAGA supercomputer infrastructure through the command line, and all analytical programs used are monitored through […]
