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
