A new study by researchers at the Max Planck Institute for Evolutionary Biology (MPI-EB) sheds fresh light on one of the most debated concepts in biology: evolvability. The work provides the first experimental evidence showing how natural selection can shape genetic systems to enhance future capacity for evolution, challenging traditional perspectives on evolutionary processes.

The research is published in the journal Science. A related Perspective article also appears in Science.

The ability of organisms to generate adaptive genetic variation is crucial for evolutionary success, particularly in changing environments. The MPI-EB study investigates whether natural selection operates not merely as a “blind” process driven by random mutations but could actively favor mechanisms that channel mutations toward adaptive outcomes.
