Gene flow is a fundamental evolutionary force in adaptation that is especially important to
understand as humans are rapidly changing both the natural environment and natural levels …

The unit of adaptation is usually thought to be a gene or set of interacting genes, rather than
the whole genome, and this may be true of species differentiation. Defining species on the …

Anopheles gambiae is the principal vector of malaria, a disease that afflicts more than 500
million people and causes more than 1 million deaths each year. Tenfold shotgun sequence …

The fidelity of DNA replication together with repair mechanisms ensure that the genetic
material is properly copied from one generation to another. However, on extremely rare …

Now updated for its second edition, Population Genetics is the classic, accessible
introduction to the concepts of population genetics. Combining traditional conceptual …

This report of independent genome sequences of two natural populations of Drosophila
melanogaster (37 from North America and 6 from Africa) provides unique insight into forces …

Although the X chromosome is usually similar to the autosomes in size and cytogenetic
appearance, theoretical models predict that its hemizygosity in males may cause unusual …

Background: Caenorhabditis elegans is a major model system in biology, yet very little is
known about its biology outside the laboratory. In particular, its unusual mode of …

Bilingual individuals need effective mechanisms to prevent interference from one language
while processing material in the other. Here we show, using event-related brain potentials …

Speciation—the splitting of one species into two—occurs by the evolution of any of several
forms of reproductive isolation between taxa, including the intrinsic sterility and inviability of …
