Answer: you didnt give me enough info for me to answer the question but let me know if this info helps
Explanation: a sets. Getting DNA from ancient bones and teeth is still a fairly new procedure, and it has largely focused on the stuff from humans. But modern sequencing techniques pick out all the genetic material in a sample, which frequently includes a lot of contaminating bacteria. For this reason, “normally 95 percent, 99 percent of the data was just thrown into the Dumpster,” Simon Rasmussen, who studies pathogen evolution at the Technical University of Denmark and co-authored the study, told me. The idea was to look through all this genetic detritus for signs of Yersinia pestis. When people die of the plague, their blood has high levels of bacteria, which leave a distinct genetic signature in the dental pulp inside teeth.
