I just came across an article distributed by the National Public Radio (NPR) about a scientific beak though in DNA sequencing. This article just goes to show that DNA can answer current question about crimes, relationships and health but it can also help us look into our past.
Scientists have used DNA lurking inside the teeth of medieval Black Death victims to figure out the entire genetic code of the deadly bacterium that swept across Europe more than 600 years ago, killing an estimated half of the population…
People back then had no access to modern antibiotics and were likely weakened by other infections as well.
Poinar says the ancient Black Death DNA looks so similar to Yersinia pestis that still infects people today that researchers believe the medieval strain must be the ancestor of all modern strains.
The Natural History Museum of Denmark’s Thomas Gilbert says the insights that come from these studies will be of interest not only from a historical perspective, but also to help scientists understand how deadly epidemics have emerged in the past so that they can get ready for what might come in the future.

While this field of research might not seem very practical at first glance there is a wealth of knowledge about, diseases, bacteria and the ways we interact with them and how they spread and change.
