Scientists have used gene technology to understand more about the make-up of the evolution of brassicas - paving the way for bigger and more climate resilient yields from this group of crops that have been grown for thousands of years.

Researchers combine phylogenetic reconstructions and computational behavioral analysis to show that army ant mass raiding evolved from group raiding through the scaling effects of increasing colony size. The transition evolved tens of millions of years ago and is perfectly correlated with a massive increase in colony size.
