Certainly television did evolve from radio, in a particular sense of the word. It did not, and could not, evolve by random mutation and natural selection. Radio and television components definitely are similar. That doesn't prove that an early television was once a radio, or that television and radio shared a common ancestor that has not been discovered yet. It is simply evidence that common component building blocks can be assembled to create different products. Radio and television are both products of human intelligence. Their similarity is evidence of a common designer, not random chance. Phillip Johnson explains it this way: Tim Berra is a professor of zoology at Ohio State University. He wrote a book that was published by the Stanford University Press with the title Evolution and the Myth of Creationism: A Basic Guide to the Facts in the Evolution Debate. Berra's book has much the same purpose as this book [Defeating Darwinism]. It aims to explain, for nonscientists, how good thinkers should view the conflict between evolution and creation. Here is Berra's explanation of "evolution," which comes illustrated with photographs of automobiles in the middle of the book: Everything evolves, in the sense of "descent with modification," whether it be government policy, religion, sports cars, or organisms. The revolutionary fiberglass Corvette evolved from more mundane automotive ancestors in 1953. Other high points in the Corvette's evolutionary refinement included the 1962 model, in which the original 102-inch was shortened to 98 inches and the new closed-coupe Stingray model was introduced; . [a long list of changes deleted] .The point is that the Corvette evolved through a selection process on variations that resulted in a series of transitional forms and an endpoint rather distinct from the starting point. A similar process shapes the evolution of organisms. Of course, every one of those Corvettes was designed by engineers.
