This is an example of evolution, speciation and fitness for their niches. Nor could a 747 have been created in the sixties if not for the successive generations of aircraft before it. What we see in the 747 is a gradual change from the early days of flight, to the more modern, complex, craft of today. There has been a great deal of speciation of aeroplanes from the original early model, filling in niches from Tornadoes and Stealth Bombers, to luxury personal jets, to gliders and pleasure craft. Rather than refute the evolution argument, a 747 actually supports it.
Complex systems evolve from more simple ones.
While each individual item may have been built from scratch, the modern versions of most complex items we see about us have evolved from more simple structures until they fill the niches required. Even Tom Willis's pocket comb looks remarkably different from the one used by early humans. We now have many kinds of combs and brushes suited to all kinds of niches. The one in his pocket is suited for that exact purpose, being constructed from durable plastic with close teeth. If Tom Willis desires to refute evolution, he would do better to choose something that has never evolved.
