26 The Origin of Birds and Flight

evolutionists have no alternative but to produce similar scenarios of no
scientific value.
The book Avian Visual Cognition, edited by Dr. Robert G. Cook of
Tufts University, refers to the clear nature of this speculation:
The excellence of the avian design for flight, along with the paucity of
fossil evidence for transitional forms, has made the evolution of flight
in birds an area of tremendous speculation. 6
“Origin of Bird Flight Explained”, an article in the 17 January, 2003
edition of Scientific American, referred to the insufficient nature of both
the cursorial and the arboreal theories—although there is in fact no sat-
isfactory explanation at all for the origin of birds:
…But both the arboreal and the cursorial scenarios have explanatory
gaps. As far as tree dwellers go, of the hundreds of nonavian gliding ver-
tebrates around today, not one flaps its appendages. And why would
natural selection have favored the development of little protowings in a
theropod equipped with heavily muscled legs for running across the
ground? Neither theory, [Kenneth] Dial [an evolutionists biologist of
The University of Montana] asserts, adequately addresses the step-by-
step adaptations that led to fully developed flight mechanics. 7

THE ORIGIN OF FLIGHT ACCORDING TO THE CURSORIAL
THEORY, AND THE ERRORS THEREIN
The cursorial theory maintains that two-legged (or bipedal) reptiles
began flying after a series of leaps they performed while running. It
assumes that as the distance leaped increased, the reptiles used their
forelegs used for balance and propulsive force, and that eventually,
resulted in flight—without the need for any other supplementary
means.
Initiatives to explain this utopian hypothesis have taken two forms:

The “Insect Net” Model
This model proposes that the forearms of these two-legged reptiles
