Creation Moments

Mark W. Cadwallader: Can spiders grow to be the size of a house? You'll find out next on today's Creation Moments.

And now, here's our Creation Moments host, Ian Taylor.

Ian T. Taylor: The largest known beetle in the world is the aptly named Goliath Beetle. This African beetle can become almost as large as a mouse. Dinosaurs were not the largest animals ever to live. The great blue whale holds that honor. The smallest animal in the world is smaller than many insects, a newly discovered species of bat in Thailand, weighs only 6 hundredths of an ounce.

Such extremes might lead us to wonder whether those giant insects we see in the movies could ever develop. Could a spider grow to be as large as a house? You'll be happy to know that no spider, nor any other insect could get as large as a house. We can be sure of this because of the way insects breathe.

Insects breathe through small tubes along their bodies. These tubes provide oxygen directly to their internal tissues. If an insect were to grow too large, these tubes could not get enough oxygen to the tissue. This is because the larger the creature, the more internal living tissue that requires oxygen.

You and I have lungs that provide a network of surfaces equal to the size of a tennis court, and an insect our size would need a body that has the surface area of a tennis court too, which is an impossibility. Even though different creatures have different organs to supply their needs, each creature has just the right organs for its needs. This is a sign of our creator's wisdom. This fact also tells us that living things are not related to each other by evolution.
