Question from James:
Why does Richard Dawkins use the analogy of a “blind watchmaker” to describe natural selection?
Answer by SmartLX:
Straight from Wikipedia:
“In his choice of the title for this book, Dawkins refers to the watchmaker analogy made famous by William Paley in his 1802 book Natural Theology.[1] Paley, writing long before Charles Darwin published On the Origin of Species in 1859, held that the complexity of living organisms was evidence of the existence of a divine creator by drawing a parallel with the way in which the existence of a watch compels belief in an intelligent watchmaker. Dawkins, in contrasting the differences between human design and its potential for planning with the workings of natural selection, therefore dubbed evolutionary processes as analogous to a blind watchmaker.”
Essentially, natural selection clearly does not plan. Paley’s argument is that if a watch suggests the existence of a watchmaker, the supposed appearance of design in living things should suggest the existence of a designer, but on closer inspection life is not as it would have been if designed by an entity with all its faculties intact. The reasons given by Dawkins include vestigial organs and features, inefficient physical arrangements of a body’s components (like the recurrent laryngeal nerve), inefficient solutions to simple problems, easily avoidable susceptibilities to malfunction, disease and death (see here for examples in humans), and needlessly expensive competition between individual organisms. Life functions, sometimes barely, but it could be so much better if someone had actually designed it rather than natural selection procedurally applying the simplest short-term solution to everything.
