Modern high-throughput DNA sequencing has made it possible to inexpensively produce
genome sequences, but in practice many of these draft genomes are fragmented and …

The self-fertile nematode worms Caenorhabditis elegans, C. briggsae, and C. tropicalis
evolved independently from outcrossing male-female ancestors and have genomes 20-40% …

Although theory indicates that indirect genetic benefits through mate choice should be
widespread, empirical work has often either failed to detect the operation of such benefits or …

Can a history of phenotypic plasticity increase the rate of adaptation to a new environment?
Theory suggests it can be through two different mechanisms. Phenotypically plastic …

The Bateson–Dobzhansky–Muller model predicts that postzygotic isolation evolves due to
the accumulation of incompatible epistatic interactions, but few studies have quantified the …

Bumble bees are ecologically and economically important insect pollinators. Three
abundant and widespread species in western North America, Bombus bifarius, Bombus …

Background High-throughput sequencing has made it theoretically possible to obtain high-quality
de novo assembled genome sequences but in practice DNA extracts are often …

Acetylene (IUPAC name: ethyne) is a colorless, gaseous hydrocarbon, composed of two
triple bonded carbon atoms attached to hydrogens (C 2 H 2 ). When microbiologists and …

Genome size has been measurable since the 1940s but we still do not understand genome
size variation. Caenorhabditis nematodes show strong conservation of chromosome number …

In 1994 and 1996, Andreas Wagner introduced a novel model in two papers addressing the
evolution of genetic regulatory networks. This work, and a suite of papers that followed using …
