25. Useless Noise, Though
The majority of your DNA includes remnants of ancient viruses that infected your ancestors. However, this notion of “junk”/”noise” DNA is evolving. Increasingly, what was once considered useless is found to have regulatory or structural functions. This discovery challenges our understanding of genetic material.

In fact, a person lacking “junk DNA” would likely die, indicating its vital role in biological processes. While the exact functions of this DNA are not yet fully understood, ongoing research sheds light on its significance.
