A design must be considered improbable if it is highly functional and durable yet too complex to have come about spontaneously or by intermediate steps. Think of the subway system in any large metropolitan area. Could the combination of tracks, stations, tunnels, signs, vending machines, stairwells, lighting, trains, billboards, ticket booths, turnstiles, benches, platforms, security measures, and restrooms have happened all at once or did it come about by stages? If these commuter systems were to follow the tenets of the theory of evolution, the tracks going off in every direction might be called links to the stations called species. How does one get from station to station without the tunnel, train, and tracks? In the theory of evolution, these kinds of intermediaries are abundantly missing.
The wombat has an upside-down pouch. Scientists presume, and it makes sense, that position prevents dirt from entering the pouch when the wombat is digging in the ground. Could there have been transitional species with pouches situated sideways, or did the first wombats have to scoop dirt out of their pouches every day?
