Fully Developed Organs
All species appear fully developed, not partially developed. They show design.There are no examples of half-developed feathers, eyes, skin, tubes (arteries, veins, intestines, etc.), or any of thousands of other vital organs. Tubes that are not 100 percent complete are a liability; so are partially developed organs. For example, if a leg of a reptile were to evolve into a wing of a bird, it would become a bad leg long before it became a good wing.
