THE MIRACLE OF MIGRATION IN ANIMALS

gradual addition of small coincidental advantages gained in the
course of this struggle over time. A small bird only a few weeks old
sets off on a journey thousands of kilometers long, but its success is
due to its having the necessary structure and perfect mechanisms.
Accordingly, it’s not possible for the necessary organs and behavior
to develop in stages, because for any animal lacking the necessary
equipment and skills, the chances of survival would be very slim, as
an evolutionary source mentions:

The risk of mortality during migration is great; the evolution of migra-
tion in the face of this risk is one of the aspects of this behavior that still
requires explanation. 67

But this impasse does not deter evolutionists from making fan-
tastic speculations about migration. Their most publicized scenario is
based on the retreat of icebergs, as is related in an evolutionary
source:
One widely held idea has been that glaciation explains the evolution of
migration. Some believe that advancing glaciers pushed temperate
zone birds into the tropics. When the glaciers retreated, the descen-
dants of these birds returned to their ancestral homes. Others think that
glaciers prevented tropical birds from spreading into temperate re-
gions. When the glaciers retreated, these birds were able to spread into
areas that had been ice-covered. Their descendants returned, however,
to their ancestral homes in the tropics. 68
There are serious contradictions in the explanations linking mi-
gratory behavior in animals to hereditary characteristics shaped by
coincidental effects. Information encoded in an animal’s DNA cannot
create compatibility with environmental factors or be influenced by
any aspect of an animal’s behavior. As already explained, this unsci-
entific logic emerged in an era before any knowledge of genetics. For
example, even if migration in birds began in ancient times when
moved to a different place as the icebergs retreated, that does not sup-
