The study of reproductive isolation and species barriers frequently focuses on mitochondrial
genomes and has produced two alternative and almost diametrically opposed narratives. On …

The partitioning of genetic material between the nucleus and cytoplasmic (mitochondrial and
plastid) genomes within eukaryotic cells necessitates coordinated integration between these …

The copepod Tigriopus californicus shows extensive population divergence and is
becoming a model for understanding allopatric differentiation and the early stages of …

The evolution of reproductive barriers is the first step in the formation of new species and
can help us understand the diversification of life on Earth. These reproductive barriers often …

Reduced fitness in interpopulation hybrids can be a first indication of genetic
incompatibilities that may ultimately lead to reproductive isolation and speciation. A growing …

Fundamental biological processes hinge on coordinated interactions between genes
spanning two obligate genomes—mitochondrial and nuclear. These interactions are key to …

Most aspects of the molecular biology of cells involve tightly coordinated intermolecular
interactions requiring specific recognition at the nucleotide and/or amino acid levels. This …

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

Mitochondrial genes are widely used in taxonomy and systematics because high mutation
rates lead to rapid sequence divergence and because such changes have long been …

The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …
