Aye-ayes Have Many Unusual Characteristics

Scientists use animal classification systems based on old evolutionary assumptions. The result is that many times an animal turns up that doesn’t fit any evolutionary model. An excellent example of this is a species of long-fingered lemurs called aye-ayes. They are nocturnal animals found only in Madagascar. Aye-ayes have many unusual characteristics giving a name that comes from a local phrase meaning something like “I don’t know.” Here are a few of the aye-aye’s traits:

1) They have large round eyes, which aid in night vision.
2) They use their continually growing incisor teeth to tear a hole in trees to reach grubs. Their teeth are so strong they can chew through cement blocks.
3) Their long middle finger is skeletal and has a ball-and-socket joint used to hook onto wood-boring grubs.
4) Their big toe is opposable to enable them to hang from tree branches.
5) They have fur with guard hairs they can raise to appear to double their size.
6) They use a unique system of foraging by percussive tapping on wood. They sense the echo with their bat-like ears to detect hollow areas where grubs are.
7) They build elaborate spherical nests made of leaves and branches.

Because of their teeth, nesting behavior, and long tail, your first guess might be that they are rodents. Despite the face of a possum, the teeth of a mouse, and the ear of a bat, they are classified as primates. This lemur is so unusual it has its own taxonomic family.

Aye-ayes have many unusual characteristics that point out weaknesses in the evolutionary taxonomic system. Systems such as cladistic taxonomy have gained weight as science discovers more animals like this in fossils and places like Madagascar. From an apologetics standpoint, it seems clear that God has created a variety of animals and given them characteristics to fill various ecological niches. Aye-ayes seem to be a special creation for a unique environment.

God’s Environmental Solutions

With a growing human population, environmental toxins, the warming of our planet, and the shortages of potable water, we recognize that Earth is under stress. News reports tell of people dying because of ecological problems. It is essential to understand that all of this pain, death, and turmoil are unnecessary. When God created planet Earth, He built into it many self-correcting tools for survival. If you name a major problem that threatens the long term existence of humans, I believe there is a built-in device that can correct the problem. God designed the Earth to withstand even the abuse that selfishness, ignorance, and greed have brought upon it. Here are a few examples of God’s environmental solutions:

Carbon dioxide and global warming. Several greenhouse gases contribute to global warming, but the main one is carbon dioxide. Not only do animals exhale carbon dioxide, but fires produce it, so human-caused fires are a contributor. God beautifully designed planet Earth with tools to contain carbon dioxide. Plants take it out of the air and release oxygen as a product of photosynthesis. This system is highly efficient as a single tree can take care of the carbon produced by one human. Plants in the ocean do the same thing. Human deforestation of both the land and the sea thwarts the system God put in place to sustain life on Earth. God’s environmental solutions are there if we will use them.

Water. Oceans cover roughly 3/4ths of Earth’s surface, but water shortages plague a significant percentage of the world’s population. The obvious problem is that because of minerals in the water, ocean water cannot be consumed directly by humans or most animals or plants. But the 50-quadrillion tons of minerals in the oceans, including 4.5 billion tons of uranium, have 14,000 industrial uses. God’s environmental solutions not only provide enough water for every living thing on the planet but also a wealth of minerals to sustain an advanced society.

Toxins. In the past five years, science has discovered that a Chinese brake fern (Pteris vittata) can survive on arsenic. Arsenic is a significant pollutant poisoning millions of people in the world, causing skin lesions, cancer, and other illnesses. Finding a plant that removes arsenic from the environment is a significant breakthrough. Over the past several years, we have mentioned other plants that provide environmental cleansing. Scientists have found bacteria that eat plastics and others that consume crude oil. These are more of God’s environmental solutions to tackle the plastic trash and oil spills in the ocean.

We need to allocate research funding to learn more about God’s environmental solutions to counter ecological problems. God has given us resources to repair the damage we have done to the environment. Maybe the problems we see around us will bring us to accept what God has provided and have the heart to think beyond our own selfish interests.

Elephant Ecology or Extinction

Elephant Ecology or Extinction There are those who like to change things, even if they have not investigated all the ramifications of that change. When God’s creation is involved, there are especially drastic proposals that are sometimes a product of ignorance. There is an ongoing battle between those who want to preserve elephants as a species and those who say that elephants are an ecological disaster. Instead of elephant ecology, they believe that elephants need to travel the road to extinction.

Those who want to allow elephants to go the way of the dinosaurs say that the volume of plants they need to survive makes them too destructive to justify their existence. To support such claims, they show pictures of areas decimated by elephants and tell stories about the invasion of elephants into agricultural regions. Elephants, they say, have threatened the survival of whole communities of subsistence farmers by eating the plants humans depend on.

On the other side of the fence is the “Save the Elephant” campaign in Kenya. They maintain that there is interconnectivity in the natural world between all organisms. They argue that elephants provide a variety of connections to various African ecologies. Elephants are ecosystem engineers. Scientists tell us that elephants knock over trees, trample brush, prune branches, and disperse seeds, which increases the biodiversity of the areas in which they live. Elephant ecology helps to maintain the savannas and forests.

A recent discovery connects the largest animals in the African ecology with the smallest. Herpetologist Dr. Stephen Platt has been studying the Nay Ya Inn wetland in Myanmar (Burma). He found that frogs depend on elephants in a very surprising way. As elephants travel in wetland areas, they leave Jacuzzi-size pools in the ground that stay full of water during the dry season. Frogs depend on these pools to lay eggs and develop tadpoles to maintain their populations in a fragile environment. Platt says there other small organisms that also depend on these pools for their survival. In Platt’s words: “Such microcosms of life are probably commonplace, but almost no one has bothered to look before.”

Earth’s history has been full of examples where large animals supported an ecosystem that produced not only life, but also resources for humans. Dinosaurs were huge for a reason, and it was not to make movies. Like the elephant, dinosaurs provided for humans by being the ecosystem engineers of their day. Without them, we would not have the coal, gas, iron, and many other resources that make our modern world possible.

God has provided for us in some incredible ways, and elephant ecology has opened our minds to a whole new way of seeing that.

God’s Swiss Army Tree

Most of us know what a Swiss Army Knife is. The one I had as a kid had a knife, can opener, bottle opener, nail file, corkscrew, screwdriver, and scissors all built into one six-inch container. You pulled out of the container whatever you wanted to use. While it didn’t always work well, it did a large number of things.

The mangrove is a tree which God has created to do a large number of different things. The design of the tree is ingenious. The roots of the plant filter out 90% of the salt from seawater so the plant can grow along any ocean shoreline. The leaves of the plant are waxy and thick so that the water inside the plant is stored efficiently. The roots make the plant look like it is on stilts, but their design gives stability even in the worst of storms. Those same roots sequester carbon four times more effectively than tropical rain forests.

In addition to all of those things, the mangrove is home to a wide range of living organisms. The root system is a protective breeding ground for many different species of fish as well as crustaceans, mollusks, barnacles, and turtles. Many varieties of sea-birds such as egrets and warblers nest in mangroves. There are about 60 species of mangroves in the world, and they are all beneficial. Not only do they protect the shorelines from beach erosion and shelter fisheries, but the wood is used in a variety of ways.

We take for granted all that God has done to allow us to live on this planet. Having a plant as versatile and useful as the mangrove is a great testimony to God and his wisdom in designing things that allow us to live here. We need to treasure and take care of what God has given us. Remember that one of the first jobs God gave humans to do was to “take care of the Garden, dress it and keep it” (Genesis 2:15). That responsibility is still one we should do responsibly. Data from World Wildlife Magazine, January 2017, page 5-6.
