Reproductive isolation arises during laboratory adaptation to a novel hot environment
Background: Reproductive isolation can result from adaptive processes (e.g., ecological speciation and mutation-order speciation) or stochastic processes such as "system drift" model. Ecological speciation predicts barriers to gene flow between populations ...
BMC2024Mitochondrial Pseudogenes Suggest Repeated Inter-Species Hybridization among Direct Human Ancestors
The hypothesis that the evolution of humans involves hybridization between diverged species has been actively debated in recent years. We present the following novel evidence in support of this hypothesis: the analysis of nuclear pseudogenes of mtDNA ("NUM ...
MDPI2022Genomic consequences of colonisation, migration and genetic drift in barn owl insular populations of the eastern Mediterranean
Nicolas Jean Philippe Guex, Eléonore Lavanchy
The study of insular populations was key in the development of evolutionary theory. The successful colonisation of an island depends on the geographic context, and specific characteristics of the organism and the island, but also on stochastic processes. A ...
2022Linking micro and macroevolution in the presence of migration
Sophie Myriam Hautphenne, Laurent Lehmann, Nicolas Salamin
Understanding macroevolutionary patterns is central to evolutionary biology. This involves the process of divergence within a species, which starts at the microevolutionary level, for instance, when two sub populations evolve towards different phenotypic o ...
ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD2020Global radiation in a rare biosphere soil diatom
Soil micro-organisms drive the global carbon and nutrient cycles that underlie essential ecosystem functions. Yet, we are only beginning to grasp the drivers of terrestrial microbial diversity and biogeography, which presents a substantial barrier to under ...
