What Is the Scientific Basis Of the Kashrut? Or Why Are There Dietary(Kosher) Laws?

Taq polymerase is an example of a thermophilic enzyme. Thermophilic enzymes are proteins that are stable and functional at high temperatures, typically found in organisms that thrive in extreme heat, such as thermophilic bacteria and archaea.

Taq polymerase is a DNA polymerase enzyme used in the Polymerase Chain Reaction. Polymerase chain reaction (abbreviated PCR) is a laboratory technique for rapidly producing (amplifying) millions to billions of copies of a specific segment of DNA, which can then be studied in greater detail. Taq polymerase is highly heat-stable, allowing it to function at high temperatures.

Connection to Non-Kosher Animals

While Taq polymerase itself is not naturally present in animals, non-kosher animals like pigs or shellfish could practically harbor thermophilic bacteria in their gut microbiomes if they consume contaminated water or food from geothermal environments. These bacteria could produce thermophilic enzymes like Taq polymerase.

Taq polymerase is a well-studied thermophilic enzyme, making it a clear example of a heat-stable protein. Non-kosher animals could potentially host thermophilic bacteria in their digestive systems, especially if they consume food or water from extreme environments.

Taq polymerase is a classic example of a thermophilic enzyme that could practically be associated with non-kosher animals through their microbiome.

However, the fact is that any animal can be non-kosher because the presence of thermophilic bacteria (and their enzymes) in an animal’s gut  depends on its diet and environment. Taq Polymerase live in environments like hot springs, hydrothermal vents, or geothermal areas. And any animal in these environments can contact Taq Polymerase either directly, or indirectly from thermophilic bacteria and archaea.

Link To Human Evolution and Progress

Taq polymerase has a relatively low replication fidelity, which means it has a higher error rate. For example, using too much Taq polymerase can cause unwanted DNA fragments to appear on a gel. In a similar way, Taq polymerase interferes with the emergent phase of evolution by causing error in new DNA synthesis.

This is a classic example of the subtle role diet and environment play in the evolution of organisms.
