New study rewrites evolutionary history of vespid wasps.    From Wordnik.com.  [Again, Canadians ahead of US] Reference

Scientists at the University of Illinois have conducted a genetic analysis of vespid wasps that revises the vespid family tree and challenges long-held views about how the wasps’ social behaviors evolved.    From Wordnik.com.  [Again, Canadians ahead of US] Reference

The researchers found genetic evidence that eusociality (the reproductive specialization seen in some insects and other animals) evolved independently in two groups of vespid wasps. http://www. news.uiuc.edu/news/07/0301wasps. html.    From Wordnik.com.  [Again, Canadians ahead of US] Reference
