Freshwater Mussels and Design

Humanity’s war with pollution has a surprising helper in freshwater mussels. They are susceptible to any change in the water in which they live. When anything disturbs the quality of the water, these mussels close their shells. In Poland, fifty water processing plants use these mussels to monitor any contamination of their drinking water. Technicians attach sensors to the mussel’s shells with hot glue. When four of the eight mussels close their shells, they trip a sensor alerting control computers to shut off the water supply. After three months, the mussels are removed from service and returned to the wild because they adapt to water quality and become less sensitive.

When Joe Kramarz sent this information, I thought it was a joke, but it’s true, as the National Institutes of Health reported. Our thanks to those who send us information we might miss.  In this case, we find it interesting that mussels are designed to avoid pollution in their environment. Freshwater mussels are just one example of many animals that monitor their environment, including bats, whales, corals, moles, and even groundhogs. Some of these may not directly benefit humans, but they help us understand that God has designed animals for a complex and changing world.

When God challenges Job’s understanding in Job 38-41, He refers to many things in the creation that show wisdom and design. We are still learning about many of those examples, but all of them are beyond human capacity to duplicate.
