All living things have a common design framework.
How can you tell a PC from a Mac? An android from an iphone? A ford from a chevy? A Picasso from a Rembrandt. You can really get to know and understand the designer by using, experiencing, observing his products. You can tell who made something after becoming pretty familiar with his product. God’s design framework is the same way. As an orderly creator (Cosmos) he used a common design framework for all living thing. Hence all living creatures have . . . DNA and/or RNA, sensory capability, the ability to reproduce . . .
This idea has been perverted by evolutionists, some of whom went so far as to airbrush images of animal embryos to remove differences and highlight similarities (See Icons of Evolution).
