This deals a severe blow to
the evolutionist scenario assum-
ing a progression from thermal
insulation to flight. According to
that scenario, feathers that evolved
for thermal insulation at the outset must
have a tasseled structure. Therefore, natu-
ral selection will favor only feathers providing
improved insulation—in other words, more tas-
seled feathers. This discourages progress from a tas-
seled structure to an aerodynamic one.
No fossil records show that the insulating feath-
ers’ structure began specializing in the direction of flight.
Hair-like feathers in flightless birds actually require this
development process to work in the exact opposite direc-
tion. In conclusion, not only is the hypothesis that bird feath-
ers evolved from reptile scales self-contradictory, but there is
no evidence in the fossil record to support it.
