Our understanding of bee phylogeny has improved over the past fifteen years as a result of
new data, primarily nucleotide sequence data, and new methods, primarily model-based …

Historical biogeography has a diversity of methods for inferring ancestral geographic ranges
on phylogenies, but many of the methods have conflicting assumptions, and there is no …

Reliable estimates on the ages of the major bee clades are needed to further understand the
evolutionary history of bees and their close association with flowering plants. Divergence …

Aim To use recently published phylogenies of three major reef fish families to explore global
patterns of species origin and dispersal over the past 65 million years. The key questions …

A long-standing controversy in bee social evolution concerns whether highly eusocial
behavior has evolved once or twice within the corbiculate Apidae. Corbiculate bees include …

Apidae is the most speciose and behaviorally diverse family of bees. It includes solitary,
eusocial, socially parasitic, and an exceptionally high proportion of cleptoparasitic species …

Most flowering plants establish mutualistic associations with insect pollinators to facilitate
sexual reproduction. However, the evolutionary processes that gave rise to these …

Many insects rely on symbiotic microbes for survival, growth, or reproduction. Over
evolutionary timescales, the association with intracellular symbionts is stabilized by partner …

The geological record of South American mammals is spatially biased because productive
fossil sites are concentrated at high latitudes. As a result, the history of mammalian …

Recent phylogenomic analyses based on the maternally inherited plastid organelle have
enlightened evolutionary relationships between the subfamilies of Orchidaceae and most of …
