Does a Cadillac engine need a biological and phylogenetic explanation?

In this text we briefly explore whether ridiculing material objects like a ‘Cadillac engine’, a ‘desk’, ‘gold bars in a vault’ as reduction ad absurdum in ‘dialectical duels’ or as a metaphor for teaching evolution is really phylogenetically justified, or whether that evidence really needs an explanation in the evolutionary field. The key of reading is the combination of the definition of semaphorontholomorphy by Willi Hennig, the concept of Extended Phenotype introduced by Richard Dawkins and the memetic theory by Susan Blackmore. Once these theoretical elements are considered as a whole and in an integrated way, the logical system of Hennig still shows its all-encompassing explanatory power, a good opportunity to appreciate the great complexity and elegance of phylogeny and evolution. In the perspective presented in this paper, spiders, whales, a desk, the Cadillac engine and the American flag on the Moon are considered in some way monophyletic, and then require a putative explanation even in the phylogenetic-evolutionary field.
