Thrice Out of Africa: Ancient and Recent Expansions of the Honey Bee, Apis mellifera
The results indicate that A. mellifera originated in Africa and expanded into Eurasia at least twice, resulting in populations in eastern and western Europe that are geographically close but genetically distant.
The African honey bee: factors contributing to a successful biological invasion.
This work provides a synthesis of recent research on the African bee, concentrating on its ability to displace European honey bees, and considers the genetic composition of the expanding population and the symmetry of gene flow between African and European bees.
Insights into social insects from the genome of the honeybee Apis mellifera
The genome sequence of the honeybee Apis mellifera is reported, suggesting a novel African origin for the species A. melliferA and insights into whether Africanized bees spread throughout the New World via hybridization or displacement.
The biogeography of Apis cerana as revealed by mitochondrial DNA sequence data
The non-coding intergenic region of the Apis cerana mitochondrial genome provides a rapidly evolving source of characters for study in intra-specific biogeography and phylogenetic analysis of sequence variation indicated two well supported groups of haplotypes.
Foraging specialization without relatedness or dominance among co-founding ant queens
The existence of foraging specialists among unrelated co-foundresses of the leaf-cutter ant Acromyrmex versicolor is reported on; such task specialization leaves the forager at a relative fitness disadvantage within her foundress association.
Extreme genetic differences between queens and workers in hybridizing Pogonomyrmex harvester ants
Data is presented demonstrating unexpected genetic differences between reproductive castes in a variant of the rough harvester ant, Pogonomyrmex rugosus var.
Neotropical Africanized honey bees have African mitochondrial DNA
NON-INDIGENOUS African honey bees have invaded most of South and Central America in just over 30 years1. The genetic composition of this population and the means by which it rapidly colonizes new…

A history of inbreeding is suggested which may reduce the frequency of deleterious recessive recessive alleles in the population and promote the evolution of in breeding tolerance.
Evolution of the complementary sex-determination gene of honey bees: balancing selection and trans-species polymorphisms.

A definitive demonstration of balancing selection acting at the honey bee csd gene is provided, insights into the molecular determinants of csd allelic specificities are offered, and three different hypervariable repetitive regions in csd are present in the three species, suggesting variable mechanisms underlying allelicspecificities.
Biogeography of Apis cerana F. and A. nigrocincta Smith: insights from mtDNA studies
This study adds new data from Korea and the Philippines to earlier mitochondrial DNA (mtDNA)-based studies of the phylogeography of Asian cavity-nesting honeybees, revealing 41 haplotypes that appear to be strongly influenced by changes in sea-level during Pleistocene glaciations.
