According to the evolutionary hypothesis man is related to the animal
kingdom by descent from a brute ancestor, who, apelike in appearance,
is the common ancestor of ape and man. The evidence of such derivation
is believed to be:
i. Rudiments of structure which were useful in some brute ancestor.
There remain in man a few elementary muscles for twitching the skin, as
in the forehead; and it is pointed out that many animals have such
muscles at the present time, and it is argued that the ability of some
men to move the whole scalp points to the existence of muscles with such
function in our brute ancestors. The vermiform appendix in man is
termed rudimentary, being but a remnant of the much longer and more
complex appendix of the same nature in living animals today.
2. Embryonic Development. Because the young of all animals resemble one
another while in the embryo stage, and since such resemblances are
found in man, it is concluded that the evolution of man from some
related animal form must be accepted as the most reasonable explanation.
3. Some diseases are common to animals and man (tuberculosis, cholera,
hydrophobia, etc.).
4. The similarity in structure of man and the apes.
5. The fossil remains of man. Certain skulls and leg bones have been
found which are said to represent forms higher than the ape and lower
than man. On the strength of such finds it is said that the "missing
link" has now been supplied.
The Nebular Hypothesis.
The Frenchman de La Place (1827) first promulgated in modern terminology
the theory once held by Greek philosophers, that the earth and the
system in which it is a member originated from a primitive cosmic-vapor
or universal fire-mist filling all space with infinitely small atoms.
In this homogeneous mass _motion_ originated, resulting in a
concentration at one point. This condensation resulted in heat and
light. The planetary system at first consisted of a huge gas-ball which
gradually cooled, contracting into a molten mass which under the
influence of centrifugal force began to rotate. This rotation became
more rapid as the mass condensed, throwing off the planets, in which
the process was repeated (the moons being cast off), until the earth
became sufficiently cool to sustain life.
The Origin of Life.
When asked about the origin of life on earth, the evolutionists
generally reply that this is not a question for science but for
philosophy to answer. However, the
