120 The Origin of Birds and Flight

It would be irrational to expect unconscious cells, which allegedly
came into being by chance, to agree among themselves and come up
with a plan to give rise to a wing that will enable the body to fly—and
then to work until they achieved the appropriate scale and structure. In
such a case, the cells comprising the wings would need to be aware of
the functions of other organs and cooperate with them. Having achieved
the most appropriate structure, they would also have to take a collective
decision to stop evolving.

T es the ideal structure,

bird’s wing possess-

shape, and proper-
ties for flight. For example, birds use their
feathers to keep themselves aloft and bal-
anced. John H. Storer has stated in Scientific American mag-
azine that every bird has a dual remote control, which can best
be observed in slow-motion photography.
During the downward beat, the primary feathers at the
wingtips stand out at right angles to the rest of the wing and
to the line of flight. But they assume this twisted form for only
a split second during each wing beat.
They are constantly changing their
shape, adjusting automatically to air
pressure and the changing require-
ments of the wing as it moves up and
down. 1
