Evolutionists frequently point to similarities between living creatures as evidence to support their claims. For example, the bones in a human arm, a whale's fin and a bat's wing have similar structure. This, according to evolutionists, proves that the animals in question evolved from one single ancestor. However, it is mistaken to think in this way. Actually, this similarity is evidence that all living creatures have been designed according to a plan. From what we have observed in nature, it is evident that a Creator has formed all life within the scope of a similar plan, and fashioned all living creatures in accordance with their needs. When we examine the scientific evidence, the "common design" explanation emerges as the correct one.

To Prove that Animals Are Descended from a Single Ancestor, Then You Should Produce a Mechanism, but There Is None

If you claim that animals are descended from a common ancestor, it's not enough to use the similarities between animals as proof. It would be more apt to show a mechanism, but no such mechanism has yet been put forward. For example, which mechanisms transformed the forelimb of a mouse or a shrew-like animal, imagined ancestors of bats, into a bat's wing? Similarly, we can ask what mechanism caused the hind limbs of a land animal to turn into the fins of a whale? For this to happen, according to evolutionary theory, natural selection and mutation are required. However, these two mechanisms make sense only if all intermediate phases in the evolutionary process are of some advantage to the species. If the incomplete forms of the said organs afford the animal no benefit, they are a disadvantage and constitute a handicap for the animal in question. Therefore, there is no natural mechanism for developing the complex organs of animals or for producing genetic information that corresponds to them.
