Underwater Bees

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 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.” Along with ocean currents, they allow ocean vegetation to flourish.

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 runaway greenhouse heating of the earth. Life in the oceans is essential to life on land.

Here is another design feature of this planet which is critical to the long-term existence of life on Earth. In the 1950s, scientists thought that there were maybe five or six factors which 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).

Migrating Insects: Another Incredible Design

Migrating Insects - Arthropods
Arthropods

Over the years we have presented data on some amazing migrations. We have had several discussions about the Arctic tern and how it makes its incredible 12,000-mile journey. Research has shown that the Arctic tern uses multiple cues including magnetism, sight, smell, and even sound. We have also talked about whales, salmon, and sea turtles and the way they benefit multiple ecosystems by their migrations. Now we have a new migration that has just been discovered and is equivalent to 20,000 flying reindeer. It’s migrating insects.

According to the study, 2-5 million migrating insects fly over the United Kingdom each year. The study is reported in the December 23, 2016, issue of Science by a team headed by Jason Chapman. Tracking these arthropods involves the use of special radar designed to detect insects. The team estimates that the total biomass of these arthropods is 3200 tons which is 7.7 times more than the biomass of the songbirds in the same area. These are tiny creatures with some of them weighing less than 10 milligrams.

Chapman notes that these arthropods are not just accidentally caught up in the wind. Some of them climb to the top of a plant to launch their flight. Some stand on tiptoe and put out silk until the wind catches them and carries them away. The animals only launch when the wind is to the north from May to June, and in August and September, they launch when the wind blows to the south. Chapman concludes “these arthropods must have some kind of built-in compass plus a preferred direction and the genetics that change that preference as they or their offspring make the return migration.“

We would suggest the programming of the DNA of these creatures is not a product of chance. It is incredibly complex and requires an intelligent programmer. Migrating insects benefit the life forms that depend on them for food as well as having food benefits for themselves. They also avoid weather conditions that could be fatal to them. If that much is happening in the United Kingdom and Africa where the migrations end up, it most certainly is happening throughout the whole world. The complexity of this migration system over the Earth is far greater than anyone imagined.
