The repeated adaptation of oceanic threespine sticklebacks to fresh water has made it a
premier organism to study parallel evolution. These small fish have multiple distinct …

Cichlid fishes are a very diverse and species-rich family of teleost fishes that inhabit lakes
and rivers of India, Africa, and South and Central America. Research has largely focused on …

Although some lineages of animals and plants have made impressive adaptive radiations
when provided with ecological opportunity, the propensities to radiate vary profoundly …

Speciation is the process by which barriers to gene flow evolve between populations.
Although we now know that speciation is largely driven by natural selection, knowledge of …

Spiny-rayed fishes (Acanthomorpha) dominate modern marine habitats and account for
more than a quarter of all living vertebrate species. Previous time-calibrated phylogenies …

Evolutionary stasis characterizes lineages that seldom speciate and show little phenotypic
change over long stretches of geological time. Although lineages that appear to exhibit …

The first insect genome assembly (Drosophila melanogaster) was published two decades
ago. Today, nuclear genome assemblies are available for a staggering 601 insect species …

We review knowledge about the roles of sex chromosomes in vertebrate hybridization and
speciation, exploring a gradient of divergences with increasing reproductive isolation …

There is a contemporary trend in many major research institutions to de‐emphasize the
importance of natural history education in favor of theoretical, laboratory, or simulation …

Skin patterns are the first example of the existence of Turing patterns in living organisms.
Extensive research on zebrafish, a model organism with stripes on its skin, has revealed the …
