fall colors Archives - DOES GOD EXIST? TODAY

One of the great mysteries of living things is the presence of beauty. If your faith is “survival of the fittest,” you have no explanation for beauty. Things in the natural world often radiate incredible beauty that has no survival benefit or even threatens survival. The incredible color in birds and trees provides a classic example. Some birds have gorgeous colors that can make them vulnerable to predators.

Here in Michigan, we are witnessing another example of beauty with no survival value but seems designed for humans to enjoy. The green color we see in plants is due to chlorophyll, which allows plants to use photosynthesis. There are two kinds of chlorophyll molecules called chlorophyll A and chlorophyll B. Chlorophyll A absorbs blue light, and chlorophyll B absorbs red light. Green light is the highest energy of sunlight reaching Earth’s surface. Plants are green because the green light radiation is reflected away to protect the plants. In the fall of the year, the chlorophyll in the leaves is removed, and we see the remaining colors.

These facts explain why trees are green and the wisdom in the green color of chlorophyll. But why do the leaves have different colors when the chlorophyll is removed? In our area, the first fall colors that appear are the reds of sumac and poison ivy. Depending on the variety, maple trees have various colors of red, orange, and yellow. We also have multiple birch tree varieties, each with different fall colors.

Why should there be different colors we can’t see until the chlorophyll is gone? The chemistry that creates these colors is very complex. From an evolutionary view, all trees would have the one pigment that advances survival, but that is not the case. The picture gets even more complicated when we consider plants that never see sunlight, such as ferns and various grasses.

As we enjoy the incredible color in birds and trees, we can see beauty for the spiritual value it offers and the joy it brings. That is because we are created in the image of God, the creator of beauty.

The beauty of autumn’s brilliant colors is an amazing testimony to the creative wisdom of God as well as an expression of His love of beauty. The colors of fall are caused by several pigments and the interaction of sunlight and sugar.

Most of us know that chlorophyll makes leaves green. When leaves receive reduced sunlight in the fall, they also have a reduced supply of nutrients and water, causing the chlorophyll to be removed. The chlorophyll masks two pigments that have different colors. Carotene is yellow, and several varieties of anthocyanins are red. Many leaves contain tannin, which is brown and is dominant in oak trees. Sunlight acting on trapped sugar also produces anthocyanins with various sparkling colors, which is why the color is so spectacular on a sunny autumn day in a maple forest.

As the days grow shorter, the reduced amount of sunlight causes a corky wall called the “abscission layer” to form between the twig and the leaf stalk. This wall will eventually break and cause the leaf to drop off in the breeze. The corky material seals off the vessels that supplied the leaf with nutrients and water and blocks any loss of sugars from the plant.

What is especially interesting is that the leaf colors are not all the same. Some vines produce spectacular colors. Poison ivy takes on a beautiful red due to a high concentration of anthocyanin. Aspen has a high concentration of carotene producing the vivid yellows which dominate the woods in the Rocky Mountains. In Michigan, we have maples, gum, aspen, and oak, giving us spectacular colors that vary from one location to another.

The colors of fall are a great testimony to the fact that God paid attention to aesthetics in the creation. If survival of the fittest were the only criteria for choosing the chemicals that allow plants to survive, it seems that there would be one best choice. Different chemicals provide a vivid, beautiful splash of color for humans to enjoy. Beauty is not part of the evolutionary model, but it speaks of God’s creativity, giving us a wonderful and beautiful world in which to live.
