Many plant-feeding insects need microbial enzymes, such as pectinases, that degrade plant cell walls; yet some insects have overcome this dependency in a surprising way. Now researchers found that stick insects make microbial enzymes themselves. From an ancestral gut microbe, the genes for the essential enzymes simply 'jumped' as they are to their insect host.
