Before revision:  These three processes can be combined in a multitude of ways , thus generating the huge diversity of plant and animal forms we see today. The wealth of possible developmental schemes created by this combinatorial explosion is hard to survey and understand. Here, with a generative Boolean model , we demonstrate and systematically chart the extent of diversity that development can potentially produce.
