The rapidly developing ancient DNA technology is playing an increasingly important role in zooarchaeology.By analyzing ancient DNA extracted from animal remains excavated from archaeo-logical sites combined with archaeological evidence,would help us gain insights into the origin and do-mestication process of animals,the genetic characteristics of species,as well as the interactions between humans and animals.However,ancient DNA research is greatly affected by the age of the samples and the environment in which the site is located.In particular,the acidic soil environment in southern re-gions can severely erode and damage bone structure,which is extremely unfavorable to the preservation and extraction of DNA.Therefore,when conducting ancient DNA research,we must fully consider the influence of environmental factors,and optimize the extraction process of ancient DNA to ensure the accuracy and reliability of the research.
