How could immune systems of animals and plants have evolved? Each immune system can recognize invading bacteria, viruses, and toxins. Each system can quickly mobilize the best defenders to search out and destroy these invaders. Each system has a memory and learns from every attack.
If the many instructions that direct an animal’s or plant’s immune system had not been preprogrammed in the organism’s genetic system when it first appeared on Earth, the first of thousands of potential infections would have killed the organism. This would have nullified any rare genetic improvements that might have accumulated. Simply stated, the large amount of genetic information governing the immune system could not have accumulated in a slow, evolutionary sense.a Obviously, for each organism to have survived, all this information must have been there from the beginning. Again, creation.
