In your idiotic ideas file you no longer have to go back to the ancient myths, or even to centuries-old folly such as bloodletting, for we now have evolution--an idea that is promoted at this very time. One of the many inanities of evolution is its serendipity. If evolution is true, then we must believe that all manner of complex biological structures and machinery evolved (somehow) for one function, only then to enable new, revolutionary advancements to occur. Call it evolution's Law of Unintended Consequences.
Consider multicellularity. According to evolutionists, unicellular organisms aggregated and ultimately formed multicellular species. This would not have occurred without certain machines already present in the unicellular organisms. For instance, unicellular organisms have complex machines that secrete proteins whose function have nothing to do with working with other cells. But in multicellular aggregates such machines, according to evolutionary theory, were "recruited" (a favorite word in the evolutionist's lexicon) to fulfill an entirely new mission. Here is how Stuart Newman describes it:
Certain unicellular proteins and other molecules mobilize physical effects in the multicellular context that were unanticipated during their earlier evolution. To take a simple example, all single-celled organisms can secrete protein molecules into the environment around them. These molecules will generally float away, but they may serve to attract prey, repel predators, and so forth. When the external environment consists of other cells, as is the case in a multicellular cluster, the secreted molecule can form a distributed signal – a “morphogen” gradient – that can cause one end of the cluster to be different from another. The gene involved simply specifies the sequence of the secreted protein. What function the protein comes to assume in the new multicellular context has nothing to do with the evolutionary history of that gene, or the selection to which it had been subject. We have called such developmentally efficacious associations of ancient gene products with the physical effects they mobilize in multicellular aggregates “dynamical patterning modules” (DPMs). There are many other such examples.
It is another example of serendipity gone wild in evolutionary theory, but for evolutionist's it is just another event in a long Alice-in-Wonderland history of make believe events.
