Es ist eine weitverbreitete Annahme, dass es für Lebewesen vorteilhaft ist, möglichst unabhängig von anderen zu sein. Einem Forscherteam des Max-Planck-Instituts für chemische Ökologie Jena um dem jetzt an der Universität Osnabrück tätigen Biologen Prof. Dr. Christian Kost ist es nun gelungen, experimentell zu zeigen, dass es für Bakterien sinnvoll sein kann, ihre Autonomie zur Herstellung von Stoffen aufzugeben und sich von anderen abhängig zu machen. Dies bedeutet, dass nicht nur der Erwerb neuer Eigenschaften, sondern auch der Verlust von bestimmten Fähigkeiten die evolutionäre Anpassung von Bakterien an die Umwelt – und möglicherweise auch anderen Organismen – vorantreibt.
