Ecologically mediated selection against hybrids, caused by hybrid phenotypes fitting poorly
into available niches, is typically viewed as distinct from selection caused by epistatic …

Without mitochondria we would be in big trouble, and there would be a global biological
energy crisis if it were not for chloroplasts. Fortunately, genomic evolution over the past two …

De wederkerigheidsregel schrijft ons voor dat we teruggeven wat we krijgen. Dit is een
logische sociale regel die er voor zorgt dat de drempel om als eerste iets te geven, zo laag …

Sequence variation in mitochondrial DNA (mtDNA) was traditionally considered to be
selectively neutral. However, an accumulating body of evidence indicates that this …

Behavioral variation abounds in nature. This variation is important for adaptation and
speciation, but its molecular basis remains elusive. Here, we use a hybrid zone between two …

Metazoans exist only with a continuous and rich supply of chemical energy from oxidative
phosphorylation in mitochondria. The oxidative phosphorylation machinery that mediates …

Much progress has been made in the past two decades in understanding Darwin's mystery
of the origins of species. Applying genomic techniques to the analysis of laboratory crosses …

Ecological speciation is defined as the emergence of reproductive isolation as a direct or
indirect consequence of divergent ecological adaptation. Several empirical examples of …

Hybrid incompatibility (including sterility, lethality, and less extreme negative effects)
interests evolutionary biologists because of its role in speciation as a reproductive isolating …

Through the processes of natural selection and genetic drift, allopatric populations diverge
genetically and may ultimately become reproductively incompatible. In cases of prezygotic …
