The maternal care of offspring is one of the behavioral drivers that has led some bee species to have an ever-expanding social life over the history of evolution, new research out of York University has found.<\/p>\n


\n <\/section>\n

By virtue of being in a social group, the genome itself may respond by selecting more social rather than non-social genes. The behavior and social environment come first, setting the stage for future molecular evolution.<\/p>\n

In addition, the researchers have found that a similar genetic evolution happ<\/a>ened independently in different species at different times, suggesting there is a unifying principle leading to the same social trait.<\/p>\n

“There seems to be something about sociality specifically that is driving the genome to evolve in this way. It’s a very interesting finding previously reported only in ants and honeybees,” says lead researcher Associate Professor Sandra Rehan of the Faculty of Science<\/a>.<\/p>\n

Rehan and her team looked at 16 different bee species across three different independent origins of eusociality\u2014the transition from solitary to social life where bees or other species live in a multigenerational group cooperatively caring for offspring in which there is a reproductive division of labor.<\/p>\n

They also sequenced the genome of six of the carpenter bee species\u2014one from North America, three from Australia, one from Japan and another from Kenya\u2014to find out how sociability effects genome evolution. They found that caring for the species’ young in a group has in many cases led to the selection of social rather than non-social gene regulation.<\/p>\n
