Phylogenetic species recognition and species concepts in fungi. Fungal Genetics and
Biology 31, 000–000. The operational species concept, ie, the one used to recognize …

Although animal pollination is often proposed as a major driver of floral divergence,
questions remain about its importance in plant speciation. One issue is whether pollinator …

Adaptive radiation is the evolution of diversity within a rapidly multiplying lineage. It can
cause a single ancestral species to differentiate into an impressively vast array of species …

A paradigm of evolutionary biology is that adaptation and reproductive isolation are caused
by a nearly infinite number of mutations of individually small effect. Here, we test this …

Abstract The Rosea1, Rosea2, and Venosa genes encode MYB-related transcription factors
active in the flowers of Antirrhinum majus. Analysis of mutant phenotypes shows that these …

The tremendous diversity in flower color among angiosperms implies that there have been
numerous evolutionary transitions in this character. The conventional wisdom is that a large …

In the formation of species, adaptation by natural selection generates distinct combinations
of traits that function well together. The maintenance of adaptive trait combinations in the …

Despite much recent activity in the field of pollination biology, the extent to which animal
pollinators drive the formation of new angiosperm species remains unresolved. One …

High levels of species diversity in taxonomic groups have often been explained by a key
innovation. However, the difficulty in establishing a causal role between a proposed key …

Gregor Mendel was either clever or lucky enough to study traits of simple inheritance in his
pea plants; however, many plant characters of interest to modern geneticists are decidedly …
