The bdella is an impressive microscopic chemist.  During its short four-hour life span, it manages to survive in environments as diverse as fresh water, salt water or raw sewage.  In the first stage of its life cycle, it uses a flagellum (a long whip-like tail) to swim ten times faster than its favorite food, e. coli bacteria.  When a bdella spots an E. coli, it rams the bacterium and uses at least six different enzymes to bore a hole through the outer membrane of the bacterium.  The bdella then drops its flagellum, penetrates the bacterium, and starts the second stage of its life.

As soon as the bdella gets between the inner and outer membrane of the bacterium, it injects a chemical into the bacterium that kills it.  In order to keep the dead bacterium for its own use, the resourceful parasite injects yet another chemical into the bacterium's cell membrane that causes the outer coat of its prey to harden so that no other bdella can enter the bacterium.

Over the next two to three hours the bdella eats the bacterium and reproduces.  The new bdellas break through the dead bacterium's hardened membrane to start the cycle all over again.  Even in our fallen world the evidence for design is undeniable.  What enormous faith to believe all of this is a result of random mutations!  No wonder Scripture says that only the foolish can deny that God exists.

The 1/50-inch-long ice plant scale is the scourge of a common landscaping plant.  Since this creature is wingless, it was thought to spread from plant to plant by contact.  This idea has turned out to be totally incorrect.  Biologists have discovered that the ice plant scale sails the wind from plant to plant.  This insect not only has the ability to accurately sense wind velocity and direction, but can turn itself into a tiny bug-shaped parasail.

Once the insect senses a wind velocity of 10 miles per hour, it determines the wind direction with its antennae.  It then proceeds to turn its back to the breeze, rear up on its hind legs, and extend its antennae and legs.  This doubles the ice plant scale's surface area and makes it possible for the insect to be lifted and carried by the wind.  In essence, the scale makes a parasail out of its body.  Scientists found that even one-day-old insects are knowledgeable about flight are ready to migrate.

Both the intricate design and instincts with the smallest creatures testify to programming by their Creator.

Sulfate-reducing bacteria love metal.  Using complex chemistry, they are capable of dissolving objects made of metal.  These bacteria can make a sixteenth-of-an-inch hole in an inch-thick pipe within six months.  Even stainless steel and titanium can't stand up to them.  The sulfate-reducing bacteria often attach themselves to the inside of a pipe or tank and seal off their colony from the liquid inside.  Once sealed off, the bacteria start to form hydrogen gas.  Sealed under a miniature biosphere, the hydrogen accumulates and is absorbed by the metal.  The absorbed hydrogen begins to corrode the metal, making it brittle.

Isn't it interesting that this co-called simple organism can produce complex chemical reactions that can eat away man's strongest metal alloys?  Simple organisms are anything but simple!

Even the "lowest" forms of life, such as bacteria, have built-in abilities and intelligence.  Some bacteria can move toward the food they like and away from environments which are harmful to them.  The E. coli bacterium is so tiny that it has difficulty moving through water in the same way a human would have trouble swimming through molasses.  Therefore, E. coli was designed with whip-like hairs called flagella which allow it to move.

E. coli can only move when its flagella are rotating.  When rotated counter-clockwise its six to eight flagella wind together, forming a propeller that rotates at a fantastic 18,000 revolutions per minute.  This allows the bacterium to move in a straight line.  Sometimes the E. coli reverses its propeller, causing the whip-like hairs to unwrap and spin the bacterium into a tumble.

Microbiologists have yet to figure out how a bacterium knows where it wants to go in order to find food.  The bacterium must have both sensors and a memory in order to know whether or not the location it is traveling to is better than where it came from.  These remarkable abilities of even a tiny bacterium should cause anyone to question how it could possibly have evolved by random-chance mutations.

Almost all plants survive by a remarkable process which converts sunlight, water, and air into food. This incredibly complex process is called photosynthesis and is only found in living plants. Biologists have recently discovered a type of lake algae that not only feeds itself through photosynthesis, but also eats bacteria.

The average alga will consume an incredible one third of its weight (or 36 bacteria) every hour. This would be equivalent to a 150 pound person eating 1,200 pounds of food per day! The cells of the alga were designed to share a fibrous casing with flagella (whip-like tails) coming out of the top of the casing. These flagella force water into the casing, allowing the cells to consume the bacteria contained within the water.

The entire process of an alga plant capturing and digesting living bacteria is extremely complicated and could not have happened by any step-by-step process of random mutational changes. In addition to keeping the algae alive, this process keeps the bacteria population in check and makes the lake water safe for other creatures. The existence of this unique lake algae points to God's design in the balance of nature.

DNA is the master code which directs cells to produce proteins. Each cell in our body is made from thousands of different and very specific types of protein. This master code also directs the production of special proteins which make more DNA in order to reproduce an exact copy of the cell. In other words, to make DNA, you have to have DNA in the first place! How could DNA have developed when the existence of coded information on the DNA molecule is required to produce DNA from the start? This leads to the conclusion that cells could never have evolved, they simply had to have been created with the DNA code already in them!

Everywhere we look, from the microscopic molecules within every cell to the most complex plants and animals, we see undeniable evidence for our Creator.

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.

Inside of the intestinal track of termites live vast numbers of microscopic protozoa. These microorganisms enable termites to digest wood. The microscopic parasites eat the cellulose wood structure but share enough nutrients to keep their termite host alive. In order to confirm the relationship between the termites and their protozoa, scientists exposed termites to conditions that killed the protozoa but not the host termites. Everything seemed normal and the termites continued to eat wood until they dropped dead 10 to 20 days later. Both the termites and these specific protozoa within the termites survived because of a mutually beneficial relationship.

Neither can survive without the other.

This type of mutually beneficial arrangement is quite common in nature. It is also a strong argument against the evolutionary hypothesis. How did either of these creatures survive without the other one present? No one knows. According to evolution, termites and their parasites are so different that they would have evolved independently. The mechanisms of evolution do not explain how either creature could have evolved separately, let alone both at once, each dependent on the other.
