98 The Origin of Birds and Flight

Another problem for evolutionists is that the feather structure nec-
essary for thermal insulation is completely different from that used for
flying. The best thermal insulators is down—feathers without hooks,
since hooks stiffen the flight feathers. Therefore, there is no need for soft
insulation-feathers to acquire a hooked structure. Such evolutionist
claims actually contradict the mechanism of natural selection! Alan
Feduccia makes the following admission, although he is evolutionist:
. . . every feature of them [feathers] has aerodynamic functions. They
are extremely light, have the ability to lift up which increases in lower
speeds, and may return to their previous position very easily. 85
The feathers of flightless birds—chickens, for example—are very
different from those of flying birds. The feathers of flightless birds are
tasseled, rather than displaying the aerodynamic structure of those of
flying birds. Their tassels are similar to the hairs covering the bodies of
mammals—which are arranged so as to provide excellent insulation. 86
Therefore, feathers with a tasseled structure, that do not make flight pos-
sible, pose an advantage in terms of insulation.
