Scientists want to know how much animals can learn from their peers. How much animal behavior is genetic, and how much can they learn by watching other members of their species? 

Many years ago, a friend who raised golden labradors showed me how her favorite lab had learned to recognize the design and shape of an inverted can that covered a treat. She used ten similar cans, but only one had a pattern on it. She had taught her favorite dog to turn over that can to get the treat, which was an odorless biscuit to eliminate the dog using its sense of smell. 

The dog got the right can ten times out of ten, going straight to the can with the treat every time. She then took a puppy and put it with the adult dog and the ten cans. The puppy followed the adult dog one or two times, and then when it was alone, it ran straight to the can with the treat and turned it over. Clearly, animals can learn from their peers since the puppy had learned by watching the adult dog. 

Various experiments show animals learning from others of their species, but what about insects? Researchers at Queen Mary University in London trained bumblebees to do complex behavioral actions. The researchers set up a container with bumblebees and a blue lever that unlocked a door when pushed. There was also a red lever to open another door leading to a container of sugar water. The researchers successfully taught a group of bumblebees how to press the two levers in sequence to access the sugar water. 

When they added new bees to the container, the newcomers “watched the original bees and figured out how to complete the puzzle—showing for the first time that insects can learn multistep processes through social interaction.” We could challenge this experiment since bees have a built-in ability to convey information to other bees. When a bee returns to the hive after finding food, it can do a “dance” that tells its fellow bees where the food is. 

Animals and insects communicate, but language is unique to humans. The Bible story of the Tower of Babel (Genesis 11:1-9) shows how essential language is to human interaction. Animals can learn from their peers, but God gave humans alone the ability to communicate using language and symbols. Only humans can convey moral issues, beliefs, and values through grammar and vocabulary.

Design of Sunflowers for Optimum Pollination

Design of Sunflowers for Optimum Pollination

Everyone knows that sunflower heads turn to follow the Sun throughout the day, allowing them to get the maximum amount of sunlight. However, researchers have found another feature that helps sunflowers to thrive. Plant biologists at the University of California, Davis, have published a report showing the incredible design of sunflowers for optimum pollination.

The sunflower head has hundreds of tiny florets. The newest florets are at the center of the bloom, and the most mature are at the edges. Their design forms a distinctive spiral pattern from the center to the edge. Each floret blooms over two days. On the first day, the male part of the bloom opens, presenting pollen. The female stigma unfolds to receive the pollen on the second day. In some way, the florets coordinate their opening, beginning at the edge and moving toward the center. This progressive opening leaves a ring of female flowers outside the earlier stage of pollen-bearing males.

Pollinating insects (primarily bees) tend to land on the edges and walk toward the center. In that way, they pick up pollen after they have walked over the female florets. Then they carry the pollen to a different flower head for cross-pollination. This coordinated opening design attracts as many insects as possible and makes pollination as efficient as possible.

The sunflower’s circadian rhythm, influenced by sunlight, controls the opening of the sunflower’s florets. People, animals, and plants have a built-in circadian clock as part of our design. We see it in the design of sunflowers for optimum pollination.

Understanding how to develop plant cultivars that can optimize pollination is essential since the bee population has been declining. We have much to learn about God’s design in the plant and insect world. Studies like this can help us meet the food shortages affecting many people on this planet.

Missile Defense Systems and Dragonfly Brains

Missile Defense Systems and Dragonfly Brains

Researchers at Sandia National Laboratories have been studying the brains of insects to learn how to build computers that can intercept incoming missiles. Dragonflies successfully capture up to 95% of the prey they pursue – which is usually mosquitoes. The dragonfly doesn’t just aim its body at the mosquito, but rather it points its body at where the mosquito is going to be. You can see the connection between missile defense systems and dragonfly brains.

Dragonflies have specialized eyes that send data to their brains at the equivalent of 200 frames per second, which is several times faster than the human eye. The human brain has many more neurons than the dragonfly–86 billion as opposed to the 250,000. The larger number of neurons in human brains allows us to have cognition and do many things. However, dragonflies are designed to do one thing—to catch their food—and do it fast.

Dragonflies respond to a maneuver by their prey in 50 milliseconds (ms). That requires the eye to detect and transmit information to the brain in 10 ms. The brain has to calculate the dragonfly’s counter-maneuver in 35 ms to leave 5 ms for flight muscles to activate and take the dragonfly to where the mosquito will be. In-flight, the dragonfly must continually monitor the mosquito’s path and recalculate the trajectory. The speed of the process means there is time for only three or four neuron layers to act. Missile defense systems and dragonfly brains must act quickly.

Other insects have neurons designed for specific functions. For example, monarch butterflies have a navigational system that depends on the position of the Sun. Since the Sun’s position changes from morning to afternoon, the butterflies must have a designed system that allows them to always travel in the right direction. In addition to that, they need an instinct that tells them when to start their journey. Ants and bees also have neuron structures that allow them to return to their nest or hive no matter how far they get from it in their search for food.

Researchers at Sandia National Laboratories and Janelia Research Campus are studying these insect brains with the idea of building computers that will allow interception of missiles, prevent cars from colliding, and serve other practical purposes that require focus and speed. Proverbs 6:6 tells us to “go to the ant … consider its ways and be wise.” The design we see in even the simplest of God’s creatures radiates purpose and intelligence beyond that of mechanical chance.

Stop the Killing of Bees

Stop the Killing of Bees

There are many things that God has provided that we take for granted, and yet without them, we would not be able to live on planet Earth. One example is the common bee. The Earthjustice organization has been involved in trying to stop the killing of bees, and they gave some interesting statistics.

Bees fly an average of 55,000 miles (88,000 km) to produce one pound of honey. They can see colors that humans can’t see, and they communicate by dancing. Very importantly, it’s hard to realize that one-third of our food crops are dependent on bees. It takes 60,000 bees to pollinate one acre of an orchard, and without bees, we would have no almonds, apples, apricots, squash, and many other fruits and vegetables. An average hive contains about 30,000 bees.

One problem is that every year farmers apply over 5.6 billion pounds of pesticides to our country’s crops, and that is a factor in the decline of the bee population. The current alarm over the drop in the bee population is an excellent time to remember that God provided bees, not just for honey. They also sustain the food crops we need. That is why we must stop the killing of bees.

Waxworms, Common Pests that Eat Plastic

Waxworms, Common Pests that Eat Plastic

What appears to be a pest may become a solution to a problem. A recent example of that is waxworms, common pests that eat plastic.

Waxworms got their name because they eat the wax in honeycombs. That makes them enemies of bees and a curse for the honey industry and for bee growers that use bees for pollination. Studies of waxworms have shown that microbiota in their gut breaks down the beeswax and provides nutrition for the waxworms.

The Proceedings of the Royal Society B published the report of a study indicating that waxworms can also eat plastic. Specifically, they can eat polyethylene, which is a non-biodegradable plastic. They metabolize polyethylene into glycol, which is biodegradable. Polyethylene makes up a vast percentage of the 300 million tons of plastic waste generated every year.

Scientists are researching ways to harness waxworms, so they eat the waste without also destroying bees. This study shows that there are natural solutions to one of the biggest waste problems in the world today.

God, in His wisdom, gave us a wide variety of plants and animals that feed on a wide range of foods. That fact not only allows the natural world to exist, but it provides enormous benefits to human society. We need to understand more about what God has done, and science is a useful tool to do that. It was science that told us about waxworms, common pests that eat plastic.

Underwater Bees

Seagrass and Green Sea Turtle
Seagrass and Green Sea Turtle

Those of us who live many miles from the ocean may not think about what goes on under the water. Similar to the land, there is an enormous diversity of plants in the sea. Just like land plants, ocean plants have flowers and pollinate and reproduce. Seagrass grows on the floor of the ocean and provides a habitat for sea turtles, manatees, and many other marine animals. There are some 60 species of seagrass, and those grasses bloom and release pollen. Like land plants, seagrasses need something like the bees that help pollinate land plants. So are there underwater bees?

Researchers at the National Autonomous University of Mexico have reported that hundreds of crustaceans and other small insect-like animals visit plants and bring pollen with them. These invertebrates are the “underwater bees.” They allow ocean vegetation to flourish, along with ocean currents.

As scientists study ways in which carbon can be locked up to avoid high concentrations in our atmosphere, they find that the ocean is a major factor in avoiding the runaway greenhouse heating of the earth. Life in the oceans is essential to life on land.

Here is another design feature of this planet that is critical to the long-term existence of life on Earth. In the 1950s, scientists thought that there were maybe five or six factors that would be critical to the existence of life. The famous Drake Equation of how many planets could have life on them only considered five factors in its original format. Now we know there are a huge number of things that have to be “right” to allow life to exist.

Every time we find a new variable, the odds against life occurring by chance on planet Earth become greater. God’s wisdom and design can be seen everywhere around us. Truly, “the heavens declare the glory of God and the firmament shows His handiwork” (Psalms 19:1).

Bees and Quantum Mechanics

Bees on Honeycomb
Bees on Honeycomb

One of the most detailed discussions of living things is Karl von Frisch’s book Dance Language and Orientation of Bees. Von Frisch spent 40 years studying how bees communicate to other bees information about pollen sources. He referred to the honeycomb as a dance floor and described the bee making a “waggle dance” which gave other bees information where to find nectar. The bee dance indicates the direction to this food source and an alteration of the shape of the dance indicates the distance to the source. If the food source was close, the bee uses a round dance instead of the waggle dance. Von Frisch’s study catalogs what the bee does, but it doesn’t tell you how the bee does it.

Barbara Shipman is a mathematician with an interest in bees. There is a mathematical concept known as “manifolds.” Manifolds can have two dimensions, but they can have an infinite number of dimensions. One type of manifold called the “flag manifold” has six dimensions. As Shipman worked with flag manifolds, she saw patterns that were similar to the patterns of the waggle dance of the bees. Physicists use flag manifolds in dealing with subatomic particles called quarks which are the building blocks of protons and neutrons. Shipman believes that bees are sensitive to quarks and the sensitivity appears to be a reaction to a quantum field acting on the membranes of selected cells in the bees. It has been demonstrated that bees are sensitive to Earth’s magnetic field and the polarization of sunlight. Shipman is seeking to add the dimension of quantum fields to the bee’s repertoire of tools for location and communication.

If you are interested in digging into this in depth, there is an excellent article titled “Quantum Honeybees” in Discover magazine, November 1997. We have not found later discussions in the current literature, but the mystery of how bees communicate is far greater than the articles we have found on wolves, whales, and elephants. Attributing such things to chance products of natural selection is creative, but suggesting that the wisdom of a Creator is involved is far more satisfying to many of us who have studied these abilities.
