All species appear fully developed, not partly developed. They show design.a There are no examples of half-developed feathers, eyes,b skin, tubes (arteries, veins, intestines, etc.), or any vital organs (dozens in humans alone). Tubes that are not 100% complete are a liability; so are partially developed organs and some body parts. 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.c [See Figure 4.]
