giraffe Archives - DOES GOD EXIST? TODAY

In an American Scientist magazine article titled “Watchdogs of the Savanna,” Charlotte Ricker described unusual giraffe features. Here are some of those features:

HEIGHT: A giraffe can be almost 19 feet (5.8 meters) tall. For that reason, the circulatory system has to be specially designed to provide enough pressure to supply blood to the brain. That requires special features of the blood vessels, heart, and kidneys. In addition, the long neck allows giraffes to obtain food that other herbivores can’t reach and to see predators from a distance. Because of that, other animals rely on giraffes to alert them of danger.

EYES: Giraffes have the largest eyes of any land animal, allowing them to see those predators. Their long and sensitive eyelashes keep insects away and sense thorns on the acacia tree branches they eat.

PATTERN: The irregular brown markings on the giraffe are not just for appearance. They act as thermal windows with a complex circulatory system around each splotch to radiate or absorb heat.

SYMBIOTIC RELATIONSHIP: Birds called the oxpeckers have feet designed to cling to the giraffe as they eat ticks and other insects from its skin. This provides food for the oxpeckers and protection for the giraffes. Oxpeckers even clean the giraffe’s teeth.

LEGS: The giraffe’s thin legs have a “suspensory ligament,” which allows them to support their weight of up to a fourth of a ton (1270 kgs). This unusual giraffe feature gives them the ability to run up to 37 miles per hour (60 km/hr) and a kick strong enough to kill a lion.

NECK: The neck contains seven cervical vertebrae, the same as a human, but each vertebra can be nearly a foot long. Ball and socket joints connect them for a 360-degree motion range. In addition, a special ligament from the skull to the base of the tail counteracts the weight of the neck and head to relieve muscle strain.

When you see these unusual giraffe features, you have to ask how they originated. Are they the product of evolutionary processes, or were they designed by an intelligence to fulfill a specific purpose in a given environment? The more unique characteristics we see, the less likely that chance processes could have produced them. These are simplified explanations of a few of the design features of a very complex animal.

Looking at the complexity of all living things is an excellent testimony to the wisdom and planning of God. “We can know there is a God through the things He has made” (Romans 1:20).

Design of the Laryngeal Nerve in Giraffes

Atheists try to refute any notion of design in the natural world. They look for examples of what they call “bad design.” In a National Geographic documentary titled Inside Nature’s Giants, Richard Dawkins criticized the design of the recurrent laryngeal nerve in giraffes. He said, “No engineer would ever make a mistake like that.” The distance from the brain to the larynx is about two inches, but instead of going directly to the larynx, the nerve runs from the brain all the way down the giraffe’s neck and into its chest. There it makes a U-turn and runs back up the neck to connect to the larynx. In a mature giraffe, that distance can be more than 16 feet (4.9 m).

Dawkins calls it “a ridiculous detour.” Atheists refer to Jerry Coyne’s book Why Evolution is True, in which he calls this “one of nature’s worst designs.” The question is whether there is any reason for this design of the laryngeal nerve.

The laryngeal nerves activate muscles that make sounds and also aid the animal in breathing and swallowing. What atheists fail to mention is that two nerves connect the brain to the larynx. The primary nerve, called the superior laryngeal nerve, makes a direct connection from the brain to the larynx. The recurrent laryngeal nerve, which goes to the chest before returning to the larynx, also connects to the heart and has branches to the mucous membrane and muscular coat of the esophagus.

The design of the laryngeal nerve is not a ridiculous detour but an example of incredible technique, making efficient use of the nerves to allow the animal to have its long neck so it can reach food that other animals can’t. Dr. Wolf-Ekkehard Lonnig of Germany’s Planck Institute says that the system’s design demands that “the recurrent laryngeal nerve needs to be, indeed, very long.”

The lack of integrity in the best-known atheists of our day is as distressing as the hypocrisy of some TV preachers. Dawkins’ videos are popular on YouTube, even though it is hard to believe an expert in biology would not be aware of the complexity of the giraffe’s nervous and vascular system. When assuming there must be bad design, a scientist must resort to explanations that don’t match the facts. The design of the laryngeal nerve shows the wisdom that God has demonstrated in every corner of creation.
