King hypothesizes that proteins that the single - celled ancestors of animals used to interact with the extracellular environment — to capture bacterial prey by binding to their cell surface and to detect chemical signals — were later repurposed to enable cells to stick to and talk to each other.

The researchers also found that these peptides can destroy certain biofilms, which are thin layers of bacterial cells that form on surfaces.
