The Intricacies of Flight

This is Ken Ham, on a mission to call the church back to God’s Word and the gospel.


You and I breathe about twelve times a minute. But small birds breathe 250 times a minute! Now, this is due to their unique respiratory system. If it weren’t for this special system, birds wouldn’t be able to fly. Their high-energy muscles, like wings, need plenty of oxygen. Regular lungs just won’t cut it. Instead, air sacs branch throughout the body. The sacs bring oxygen straight to the heart, lungs, and stomach.

Birds don’t breathe in and out like we do. They’re able to inhale oxygen without exhaling carbon dioxide first. So, they always have a continuous supply of fresh air!

There is no way all of the pieces necessary for flight could have evolved. Flight shows the Creator’s fingerprint.
