God’s spirit also produced highly organized works in the biological sphere of creation. By means of his holy spirit, during creative days three through six, God created an astounding variety of plants and animals. (Gen. 1:11, 20-25) Thus, living things provide countless examples of complexity, symmetry, and beauty that bespeak design of the highest level.
Consider DNA (deoxyribonucleic acid), one of the chemical mechanisms involved in passing on the characteristics of organisms from one generation to the next. All living things on the earth—including microbes, grass, elephants, blue whales, and humans—reproduce using DNA. Although the earth’s creatures differ widely, the code that controls many of their inherited characteristics is very stable and has served to maintain the distinction between basic kinds of creatures down through the ages. According to Jehovah God’s purpose, the earth’s various organisms therefore continue to perform their functions in the complex web of life. (Ps. 139:16) This very effective, orderly arrangement provides further evidence that creation is the work of God’s “finger,” or holy spirit.
