An effort is underway to create conditions that might provoke evolution to generate substantially greater complexity in digital replicators. I am preparing what I call the ``biodiversity reserve for digital organisms.'' This will be based on a networked version of the Tierra software. We will attempt to get thousands of people to run network Tierra on their computers, and all of these computers will be connected into a virtual sub-net of the internet, within which digital organisms will be able to move freely from computer to computer.
