The cost of DNA sequencing continues to fall, which makes it feasible to develop genomic
resources for new model species that are well suited for studying questions in evolutionary …

Sexual selection plays several intricate and complex roles in the related processes of local
adaptation and speciation. In some cases sexual selection can promote these processes …

Adaptive radiation plays a fundamental role in our understanding of the evolutionary
process. However, the concept has provoked strong and differing opinions concerning its …

The African cichlid fish radiations are the most diverse extant animal radiations and provide
a unique system to test predictions of speciation and adaptive radiation theory. The past few …

The study of pigmentation has played an important role in the intersection of evolution,
genetics, and developmental biology. Pigmentation's utility as a visible phenotypic marker …

Ecological character displacement, mostly seen as increased differences of size in sympatry
between closely‐related or similar species, is a focal hypothesis assuming that species too …

Understanding how and why certain clades diversify greatly in morphology whereas others
do not remains a major theme in evolutionary biology. Projecting families of phylogenies into …

Even before the publication of Darwin's Origin of Species, the perception of evolutionary
change has been a tree-like pattern of diversification-with divergent branches spreading …

Sex determination mechanisms differ among animal species, but it is not clear how these
differences evolve. New sex determiners may arise in response to sexual conflicts, which …

Adaptive radiations are an important source of biodiversity and are often characterized by
many speciation events in very short succession. It has been proposed that the high …
