A forthcoming Science paper by Charles W. Whitfield, a professor of entomology at the University of Illinois at Urbana-Champaign, and others looks at the evolution of the honey-bee, Apis mellifera. EurekAlert has a summary and some pithy quotes from the author here. SNPs revealed that the honey-bee originated in Africa and then spread to Europe in two waves, resulting in genetically-distinct though nearly sympatric populations there. No word on whether these migrations could be related to human movements in any way, at least not in the summary.
Oh, and BTW, the honeybee genome has also just been published: http://www.nature.com/nature/focus/honeybee/index.html
