Immune system is irreducibly complex (Talk.Origins)

Claim CB200.4:

The human immune system is irreducibly complex, indicating that it must have been designed.

CreationWiki response:

Urochordates are marine invertebrates. While this indicates that a simpler immune system may be possible in a water environment, it says nothing about the human immune system, since humans live on land.

The fact that a simpler organism living in a different environment can have a simpler immune system, does not make the human immune system not irreducibly complex. It just shows that different immune systems are possible under the right condition.

Such studies may show where the genetic information for the human immune system came from but it does not solve the problem. It does not explain how the needed components happened to get together in the right order to produce a functioning system. Such preexisting material would also be expected if the human immune system was a result of genetically engineering an original creation.

It is unlikely that Adam and Eve would have needed much of an immune system in the Garden of Eden, but after the fall they would have needed a sophisticated one such as is seen in humans today. So the human immune system is likely the product of post fall genetic engineering by God Himself.

None of this changes the fact that the human immune system is irreducibly complex and that it indicates design.

If you look at the dates on both sources you see that Behe predates Ussery, so all this shows is that Behe’s description is simply out of date. It happens all the time in science.

This statement is bogus; it is based on flawed logic.

This includes impossible demand that those who hold to the position that irreducible complexity implies design disproves all possible evolutionary scenarios, even those that have not been invented yet.
