AI Summary

The study of ancient DNA from Chilean mummies has provided new insights into the origins of smallpox in the Americas. Researchers have found evidence that the virus was introduced to the region by European colonizers, rather than being present before their arrival. This conclusion is based on the genetic analysis of mummies from the 16th century, which showed no signs of the virus. The discovery suggests that the introduction of smallpox had a significant impact on the indigenous population, contributing to the devastating effects of colonization.
