Under which circumstances is sympatric speciation possible? An answer to this long-standing question of evolutionary biology has turned out to be challenging. In particular, models for the evolution ...

Mate choice, competition, and the variety of resources available are the key factors influencing how a species evolves into separate species, according to a new mathematical model that integrates all ...

Speciation has been considered as a primary process contributing to species diversity, but its contribution to the diversity of local communities has not been fully appreciated. Based on the theory of ...

Dealing a new blow to the dominant evolutionary paradigm, Luiz Rocha and colleagues from the Smithsonian Tropical Research Institute, Harvard University the University of Florida and the University of ...

An implicit assumption of speciation biology is that population differentiation is an important stage of evolutionary diversification, but its significance as a rate-limiting control on phylogenetic ...

The jumping of a gene from one chromosome to another can likely contribute to the birth of new species, a genetic analysis of flies reveals. The result validates an underappreciated mechanism of ...

"Supplement to The Auk"--Cover. Differentiation and speciation without extended isolation appear to be common among migratory animals. Historical oversight of this is probably due to temporal ...

Phylogeny is the representation of the evolutionary history and relationships between groups of organisms. The results are represented in a phylogenetic tree that provides a visual output of ...
