222 The Origin of Birds and Flight
But adherents of the dino-bird theory are reluctant to accept this
because they want to classify the creatures as dinosaurs, even though
this fossil provides no support for evolutionist claims. Indeed, this fossil
represents a new contradiction to evolutionists’ alleged ancestral rela-
tionships.
According to the evolutionist scenario, these dinosaurs and modern
birds both have a special bone that lets them bend their wrists. Again
according to evolutionist claims, this feature enabled them to move their
forefeet in a wide manner, to catch fleeing prey with their long arms and
gripping talons. This allegedly powerful beating movement represented
an important part of the wingbeats the today’s birds use to fly. However,
such interpretations are scientifically invalid, because flight consists of
far more complex actions than just wing beating:
Any forward beating movement gives rises to a counter impulse that
propels the bird backward. For the purpose of flight, the main flight
feathers are arranged at such an angle as to push the air back and
propel the birds forwards. As in planes, the wings have a special aero-
foil shape, which causes air to flow faster over the upper surface than
the lower. This, according to the Bernoulli principle, reduces air pres-
sure on the upper surface and creates lift. This is the main factor in
take-off, but there is also the question of Newton’s Third Law—the
reaction to the air being propelled downward.). 192
In addition, the structure of a wing hypothesized to catch prey is
very different from that created for beating in flight. A feathered wing is
no advantage to a bird using its wings to catch prey, because a feathered
wing’s broad surface will only increase air resistance and make move-
ment more difficult. If, the bird flapped for hunting, as evolutionists
maintain then its wing structure should help the bird move forward by
pushing air back. Therefore, it would be a greater advantage for the
bird’s wings to let air pass through them, like a sieve or flyswatter. Thus
evolutionist accounts are full of illogicalities that conflict with their own
claims.
