age 56, without marked spurts or plateaus. At this stage steril-
ity became severe. 106
After these experiments, Mayr reached the following
conclusion:
Obviously any drastic improvement under selection must seri-
ously deplete the store of genetic variability. . . The most fre-
quent correlated response of one-sided selection is a drop in
general fitness. This plagues virtually every breeding experi-
ment. 107
One of the most important texts dealing with this subject
is Natural Limits to Biological Change written by biology profes-
sor Lane P. Lester and molecular biologist Raymond G.
Bohlin. In their book's introduction, they write:
That populations of living organisms may change in their
anatomy, physiology, genetic structure, etc., over a period of
time is beyond question. What remains elusive is the answer to
the question, How much change is possible, and by what ge-
netic mechanism will these changes take place? Plant and ani- Harun Yahya (Adnan Oktar)
mal breeders can marshal an impressive array of examples to
demonstrate the extent to which living systems can be altered.
But when a breeder begins with a dog, he ends up with a
dog—a rather strange looking one perhaps, but a dog nonethe-
less. A fruit fly remains a fruit fly; a rose, a rose, and so on. 108
The authors studied this subject with scientific observa-
tions and experiments and arrived at two basic conclusions:
1) No new genetic data can be obtained without external
interference in the genes of organisms. Without such interfer-
ence, new biological data cannot appear in nature. That is,
new species, new organs, and new structures cannot come
