Animals Growing Crops

Animals Growing Crops

We generally think of farming as a human enterprise, but there are cases in the natural world of animals growing crops. In most cases, the crop they are raising could not survive without the animal tending it. Some good examples are living things that eat fungi or algae. 

Researchers at Kyoto University in Japan studied red algae called Polysiphonia. These algae have a symbiotic relationship with a species of damselfish (Stegastes nigricans). Red algae look like a brown carpet, and the damselfish make sure that the carpet is not disturbed. If any other species of algae shows up among the red algae, the damselfish will nip it off and take it out of the fish’s territory. If the damselfish is removed from the area, the red algae can’t survive. So it appears that the damselfish are critical to the survival of the red algae and vice versa. 

There have been other studies of certain species of ants, termites, and ambrosia beetles that grow fungi for food. Some of these “farmers” even use bacteria to produce pesticides to protect their fungus crops. How do such symbiotic relationships happen? Evolutionists suggest that initially, the animal had a varied diet but becoming dependent on one thing offered such an advantage that the animal gave up any other foods. 

The difficulties with the evolutionary explanation are many and quite complex. The nutritional issues are a problem because a single source of nutrition must have a balanced collection of minerals. Going from a varied diet to a single food does not seem to be an evolutionary advantage. Defending the food source is also an issue. For example, when the researchers removed the damselfish, other fish and sea urchins had eaten all of the red algae within days. 

Another explanation is that symbiotic relationships are part of the design of every animal’s genome. The earliest fossil remains of many animals show that a symbiotic relationship was already in place. We suggest that animals growing crops is part of God’s design. He gave them the genetic messaging and instinctive drive necessary for them to survive.

You Are a Spaceship with a Full Crew

You Are a SpaceshipOne of the most interesting sites on the web is the “Astronomy Picture of the Day” produced by NASA. This website features a new picture every day, usually of objects in deep space with an explanation of the image. On August 18, 2019, there was a beautiful artistic rendition of a human with a star-filled background titled “Human as Spaceship.” (Because of copyright we can’t show you the picture, but you can see it HERE.) The opening line of the explanation is, “You are a spaceship soaring through the universe.”

The point of the presentation is that as we soar through the universe, we are not alone. We are the captains of our ships, our human bodies because we are not a singular living organism. There are a massive number of separate organisms that exist inside our bodies that do specific things for us. They help digest food, fight disease and infection, and carry vital materials on a liquid highway (your bloodstream) from one end of your body to the other. These organisms are the crew of this spaceship. They are bacteria, fungi, and archaea, and they actually outnumber your own cells. Science still doesn’t know what many of these organisms do, but they have their own DNA, and together they make up the human microbiome. You are a spaceship with a massive crew.

We sometimes seem to view God’s creation of the human body as a process similar to building a machine. To build a machine you would put together pre-manufactured parts in a prescribed way. To build a working and living human body requires a host of communities which do the jobs they were designed to do in ways that science is just beginning to understand.

David said it best in Psalms 139:14: “I am fearfully and wonderfully made: marvelous are your works.”

Biomass on Earth Measured

Biomass on Earth Mostly Plants
Biomass is the mass of living biological organisms. If you lumped all living things by category, what group of organisms do you think would have the greatest biomass on Earth? We aren’t talking about the number of individuals, but the mass of the different lifeforms.

The Proceedings of the National Academy of Sciences on May 21 published a study of the different areas of the world and what form of life dominates in those areas. (Click Here to read the full report.) Plants contribute the primary biomass in the terrestrial environment. Animals are primary in the marine environment. Bacteria and archaea (single-celled microorganisms) dominate the deep subsurface environment.

You may find the results surprising. The total biomass of Earth consists of 80% plants. Bacteria make up the second largest biomass at 15%. After that in descending order are fungi, archaea, protists (unicellular organisms that sometimes form colonies), animals (including humans), and viruses. Soil fungi, protists, soil archaea, arthropods, annelids, and livestock all exceed humans in their biomass. Only wild mammals, nematodes, and wild birds have smaller biomasses than humans. In the marine environment the biomass is much smaller than on land, and after animals, the greatest biomass is in protists, archaea, fungi, and finally bacteria. It is interesting that tiny Antarctic krill contribute about the same biomass as humans.

As you think about the biomass on Earth, it becomes evident that for human life to exist, we need a huge biomass of supporting life-forms. It becomes apparent that we must take care of all of the living things that support us. It is also obvious that before human life could exist on Earth enormous preparation was required.

We have to be reminded of the words of the psalmist in Psalms 8: “When I consider your heavens, the work of your fingers, the moon, the stars, which you have set in place, what is man that you are mindful of him, the son of man that you care for him… You have made him ruler over the works of your hands; you put everything under his feet: all flocks and herds, and the beast of the field, the birds of the air, and the fish of the sea, all that swim the paths of the sea.”

Soil Studies Speak of God’s Preparation for Humans

Healthy Soil
There is an economy of language in the Hebrew descriptions of the Bible. In Genesis 2:8-9 for example, the Bible says: “Now the Lord God had planted a garden in the east, in Eden; and there he put the man he had formed. The Lord God made all kinds of trees to grow out of the ground…”

We can learn a lot from those verses. They tell us that the Lord planted something, he did not “zap” something into existence. Later the man was told to tend the garden (verse 15), suggesting that it needed care to continue to provide for the man’s needs and later for the woman’s needs. How long was it after God planted the trees before they began to produce fruit? What did Adam and Eve have to do to take care of the garden? How long was it before Adam and Eve sinned? What else did God need to do in the process of planting the trees?

This last question opens the door to a great deal of understanding that science has gained in recent years through the study of soil chemistry. Plants do not grow in sterile sand. For soil to nourish plants so that they can feed us, much careful science has to be applied. Modern soil scientists refer to “healthy soil” meaning that it is rich in organic material, is crumbly, and has the right chemical profile. To have these things, the soil must contain microbes including bacteria, fungi, nematodes, and protozoa. A teaspoon of healthy soil can hold more microorganisms than there are people on Earth.

We now know that there is a symbiotic relationship between plants and soil microbes. Plants use the sun’s energy to pull carbon dioxide from the air and create a carbon-rich nutrient packet to allow growth. Oxygen is released in that process. The plants also leak nutrients to the microbes, and the microbes supply plants with other nutrients they have extracted from the minerals in the soil. The fungi produce an underground network that brings water and carbon to the plants. When insects begin to feed on a plant, fungi filaments called hyphae help the plant bring tiny soil nematodes that feed on the insects.

When humans abuse the soil and interrupt this system, we have to artificially add chemicals to do what organisms in the soil were designed to do. The chemicals of modern farming could be reduced or eliminated if farmers worked on building healthy soils. The Garden of Eden was a place of healthy soil. God used incredible wisdom and intelligent design to build a system that would meet human needs. This was done in God’s time and was not a magic show, but a consciously built system that has sustained all living things for a very long time. Proverbs 8:22-31 tells us that wisdom was involved in all of this planning and design, and Romans 1:18-22 lets us know that all of this is a testimony to the existence of God.

There is a wonderful article in the April/May 2017 issue of National Wildlife page 35 (available online http://www.nwf.org/News-and-Magazines/National-Wildlife/Gardening/Archives/2017/Soil.aspx) that documents all of this and shows us the complexity of God’s soil science.
