Pääbo 1986; Montiel "et al." 2001), as well as various sources of artificially preserved tissue (such as the chemically treated mummies of ancient Egypt). However, mummified remains are a limited resource. The majority of human aDNA studies have focused on extracting DNA from two sources that are much more common in the archaeological record – bone and teeth. Several other sources have also yielded DNA, including paleofaeces (Poinar "et al." 2001) and hair (Baker "et al."
