Ancient DNA in ice, such as the Ötzi the Iceman (Handt "et al." 1994), or through rapid desiccation, such as high-altitude mummies from the Andes (c.f. 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."

Prompted by Heuvelmans' naming the Iceman "Homo pongoides", the FBI was informed that the subject might potentially be a human murder victim, but the agency did not investigate, possibly due to many believing it was a hoax. Sanderson, then science editor for "Argosy" magazine, authored an article about the Iceman in the April 1969 issue that featured the headline, "Is this the missing link between man and the apes?"
