No, nor am I saying that they are designed. My point is simply that, as one following science, if talk of a designer implies someone who got involved miraculously in the process, that idea is simply inappropriate in this context. One must explain the adaptedness of organisms by natural means. This one can do by invoking natural selection, the differential survival of certain organisms, against a background of modern genetics. I believe that, for reasons not connected with their needs, organisms vary.
Some organisms survive and reproduce.
Some do not. Those that do succeed, have on average variations not possessed by the losers, and those variations, although they appeared for no good reason, helped the winners to win. Given enough time, since the variations are heritable, one gets evolution. More significant, one gets the evolution of adaptations. The argument is simple, but not simplistic.
