THE METHOD OF ARGUMENT

The Method of Argument ~ 92 ~ the simpler forms came first and the more developed forms came later. 3. Another feature of the evolutionary process is that, in spite of the difference in species, life forms are marked by many resemblances in their biological systems. For instance, a fish resembles a bird; a horse skeleton resembles a man’s and so on. It follows from this that all the living species have descended from the same family having one common ancestor. 4. How did one species follow another? Did some transmutation take place? It becomes clear when we think of how an animal gives birth to many offspring, not all of which are uniform in their features, many actually being quite different from each other. These differences develop in the next generation and go on developing according to the process of natural selection. After hundreds of thousands of generations, this difference is increased to the extent that a small-necked sheep turns into a long-necked giraffe. This
