Early in the game, clicking on the "cloning" option in the lab will cause Lex to say that "I might do something about that later". Later on, and I don't know what the trigger is, clicking on the option will instead cause Lex to go through all of his old projects, and discover an old, failed, Superman clone inside a tube. This inspires Lex, and opens up a new heist. You only have do do it twice, unfortunately, it has a really high chance of turning up "miscellaneous parts" which are worthless. Eventually, you'll get all the stuff Lex needs, and you can start cloning. Galatea is available from the start, but takes 30 days to gestate.
