A recent study of signaling pathways in Caenorhabditis elegans lays the next row of bricks in this foundation. One of the enduring challenges in biology is to learn how the amazing complexity and diversity of life forms arise from a limited repertoire of heritable factors. To understand the emergent properties of biological systems it is necessary to first map the functional organization of the complex biological networks that underlie them. Many levels of function will need to be analyzed systematically to arrive at this goal. Mapping molecular interactions such as proteinprotein protein-DNA and RNA-RNA interactions will help define structural and regulatory relationships. However understanding organizational principles that determine how different parts of these networks are coordinated will require uncovering functional dependencies that may not be reflected in direct physical interactions for example between actin- and tubulin-dependent cellular processes 1 . Large-scale mapping of genetic interactions in model organisms offers a powerful approach to tackle this challenge. A recent genetic-interaction study published in Journal of Biology by Byrne et al. 2 focusing on signaling pathways of the nematode worm Caenorhabditis elegans .
