Did immune systems evolve?

Biological immune systems can recognize bacteria, viruses, and toxins that invade the body. Each system can quickly mobilize just the right type of defenders to search and destroy these invaders.

Each system also has a memory that learns from every attack so that the defense is quicker and more effective the next time.

If the extensive instructions that direct the immune system of a plant or animal were not already programmed into the organism’s genetic system when the organism first appeared on the earth, any infection would have quickly destroyed the organism. This would have nullified any genetic changes that might have accumulated.

The genetic information governing the immune system could not have accumulated in a slow evolutionary way. Immune systems became critical for survival after the Fall when sin and death changed the order of things. Yet the very existence of these systems testifies to a mastermind Designer.

How could the immune system of animals and plants have evolved? This very basic question still has no answer.1

Our Mission

We exist to glorify and honor God by equipping Christians to diligently “go and make disciples” and contend for the faith with gentleness and respect—in a morally and spiritually bankrupt culture.

“But ask the beasts, and they will teach you; the birds of the heavens, and they will tell you; or the bushes of the earth, and they will teach you; and the fish of the sea will declare to you.

Who among all these does not know that the hand of the LORD has done this?

In his hand is the life of every living thing and the breath of all mankind.”
(Job 7-10)
