  • An abundance of beneficial mutations

    Despite its key importance, the genetic architecture of adaptive processes remains largely unresolved. Now a team of researchers from Vetmeduni Vienna, experimenting with fruit flies, has succeeded in solving at least a part of this puzzle. They were able to show that many genes can contribute to ad more

  • Genome Duplication Drives Evolution of Species

    Polyploid plants have a duplicate set of chromosomes. As a result, large-scale genetic changes are therefore possible in the new species, making it more adaptable in comparison with the parental species, as has now been proven by UZH researchers with rockcress. Many wild and cultivated plants arise more

  • Mapping a genetic risk

    The more information you have, the better able you are to predict what will happen next. Clinicians and health researchers often look at gene mutation to predict whether a fetus is at risk for a birth defect, or a person is at risk of developing a disease, but these predictions are not always accura more

  • Human influence on orangutans

    Evolutionary Biology The numbers of orangutans and their geographic distribution declined dramatically after the late Pleistocene. Experts have proposed climate change and human activities as possible causes. Synthesizing available archaeological, genetic, and behavioral data, Spehar et al. more

  • Hybrid camouflage variation

    Evolutionary Biology![Figure][1] Hybrid snowshoe hares can stay brown in snowless winters. CREDIT: MAURITIUS IMAGES GMBH/ALAMY STOCK PHOTO Snowshoe hares molt from a brown coat to a white coat in winter. In some populations, however, where winter snow is less extensive, hares molt from a more

  • Multicellular survival as a consequence of Parrondo’s paradox [Biological Sciences]

    In the face of inevitable aging and death, Nelson and Masel (NM) (1) argue that alternating life history stages between multicellularity and unicellularity enable the survival of multicellular lineages. This is exactly parallel to the game-theoretic Parrondo’s paradox (2), in which two individually more
