Genesis 1:20
“And God said, Let the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth in the open firmament of heaven.”

It is likely that you were taught in high school that birds evolved from dinosaurs – specifically from therapods, the suborder that contains tyrannosaurus, velociraptor, and deinonychus. This is such an article of faith for evolutionists that they now usually refer to dinosaurs as non-avian dinosaurs – birds being avian dinosaurs. With the suggestion gaining ground that many therapods might have been covered with feathers, we can see that the stage has been set for the evolution of birds from dinosaurs to be “settled science”. It is certainly in order, therefore, to raise some problems with this apparently settled position.

One problem is that of how the animals breathe. Bird lungs produce a sort of “flow through” ventilation, where air is moved through them by air sacs almost continuously. This enables a very efficient exchange of oxygen and carbon dioxide – much more so than the in-and-out breathing of extant reptiles, which is much the same as that of mammals. Studies of fossil impressions of sinosauropteryx suggest that their airways are more like those of extant reptiles, such as crocodiles. Any transition form between the two types of lungs would find it impossible to breathe, and so would die.  Even if certain dinosaurs had avian lungs, all this does is push the evolutionary problem back a few generations.

Bird lungs show that they were designed for purpose, the way that God meant them to be, on day five of creation – whereas dinosaurs must have been made on day six.

Prayer: We love Your word, Lord, and we know that it speaks the truth of everything on which it touches. Amen.
