how it came about. And this is a very profound question which every-
body skirts, everybody brushes over, everybody tries to sweep under
the carpet.

The fact is that the majority of these complex adaptations in nature can-
not be adequately explained by a series of intermediate forms. And this
is a fundamental problem. Common sense tells me there must be some-
thing wrong. 51
As his statements show, there can be no question of an evolutionary
link between the two-directional reptile lung and the one-directional
bird lung. It’s impossible to establish any transitional model between
these two pulmonary structures. A terrestrial animal must constantly
breathe to survive, and any radical change to its lungs will inevitably
end in death in a matter of minutes. Yet according to evolution, this
change must have occurred over millions of years
Another point is that reptiles have a diaphragm-based respiratory
system, whereas birds do not. These different structures again repudiate
claims of the one type evolving into the other.
John Ruben, an authority on respiratory physiology, comments:
The earliest stages in the derivation of the avian abdominal air sac sys-
tem from a diaphragm-ventilating ancestor would have necessitated
selection for a diaphragmatic hernia in taxa transitional between thero-
pods and birds. Such a debilitating con-
dition would have immediately
compromised the entire pulmo-
nary ventilatory apparatus and
seems unlikely to have been of
any selective advantage. 52
