If it is crucially different, then that difference ought to be
measurable. Got any ideas? One possibility might be modularity,
although modularity can be favoured in Darwinian evolution too, so as
to increase evolvability.

See eg Pepper (2000), "The evolution of modularity in genome architecture",
