Native bees' exotic origins reveal cross-pollination

Ancestors of a distinctive pollinating bee found across Australia
probably originated in tropical Asian countries, islands in the
south-west Pacific or greater Oceania region, ecology researchers
claim. Describing the likely dispersal corridor for the ancestral
lineage of the bee genus Homalictus will help understand the social
evolution of the vibrant halictine bees, researchers say.
