DEVOTION AMONG ANIMALS

in his book The Origin of Species:
Natural selection can do nothing until favourable individual dif-
148
ferences or variations occur.

LAMARCK'S IMPACT

So, how could these "favorable variations" occur? Darwin tried to
answer this question from the standpoint of the primitive under-
standing of science at that time. According to the French biologist

Chevalier de Lamarck (1744-1829), who lived before Darwin, living
creatures passed on the traits they acquired during their lifetime to
the next generation. He asserted that these traits, which accumu-
lated from one generation to another, caused new species to be
formed. For instance, he claimed that giraffes evolved from an-
telopes; as they struggled to eat the leaves of high trees, their necks
were extended from generation to generation.
Darwin also gave similar examples. In his book The Origin of
Species, for instance, he said that some bears going into water to find
food transformed themselves into whales over time. 149
However, the laws of inheritance discovered by Gregor Mendel
(1822-84) and verified by the science of genetics, which flourished in
the twentieth century, utterly demolished the legend that acquired
traits were passed on to subsequent generations. Thus, natural se-
lection fell out of favor as an evolutionary mechanism.

NEO-DARWINISM AND MUTATIONS

In order to find a solution, Darwinists advanced the "Modern
Synthetic Theory," or as it is more commonly known, Neo-Darwinism,
at the end of the 1930's. Neo-Darwinism added mutations, which are
distortions formed in the genes of living beings due to such external
factors as radiation or replication errors, as the "cause of favorable vari-
ations" in addition to natural mutation.
