Michael Price, of Science Magazine, reports on the genetic effects on the American Indian Nation Tsimshiam in British Columbia by the unfortunate variety of diseases and infections which diminished the local population upon contact with Europeans. The small amount of people who survived were able to pass down their immunity to their descendants. In the present time, studies show around 175 years ago, “infectious diseases brought by Europeans… have molded the immune systems of today’s indigenous Americans, down to the genetic level.”
"Using a technique known as whole exome sequencing, researchers—including Tsimshian scientists Barbara Petzelt and Joycelynn Mitchell—sifted through the DNA for genes related to immune response. They then sequenced DNA samples from 25 Tsimshian living near Prince Rupert today. Comparing the two sets of genes, the team discovered several immune-related gene variants that were rare among the living."
