Ancient DNA Studies On Human Remains
Due to the considerable anthropological, archaeological, and public interest directed towards human remains, it is only natural that they have received a similar amount of attention from the DNA community. Due to their obvious signs of morphological preservation, many studies utilised mummified tissue as a source of ancient human DNA. Examples include both naturally preserved specimens, for example those preserved in ice, such as the Ötzi the Iceman (Handt et al. 1994), or through rapid desiccation, for example 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, and 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. Recently, several other sources have also yielded DNA, including paleofaeces (Poinar et al. 2001) and hair (Baker et al. 2001, Gilbert et al. 2004). Contamination remains a major problem when working on ancient human material.

“Even as fog continues to lie in the valleys, so does ancient sin cling to the low places, the depressions in the world consciousness.”
—Dewitt Bodeen (1908–1988)
“Here [in London, history] ... seemed the very fabric of things, as if the city were a single growth of stone and brick, uncounted strata of message and meaning, age upon age, generated over the centuries to the dictates of some now all-but-unreadable DNA of commerce and empire.”
—William Gibson (b. 1948)
“These studies which stimulate the young, divert the old, are an ornament in prosperity and a refuge and comfort in adversity; they delight us at home, are no impediment in public life, keep us company at night, in our travels, and whenever we retire to the country.”
—Marcus Tullius Cicero (106–43 B.C.)
“Just as love is an orientation which refers to all objects and is incompatible with the restriction to one object, so is reason a human faculty which must embrace the whole of the world with which man is confronted.”
—Erich Fromm (1900–1980)
“Men nowhere, east or west, live yet a natural life, round which the vine clings, and which the elm willingly shadows. Man would desecrate it by his touch, and so the beauty of the world remains veiled to him. He needs not only to be spiritualized, but naturalized, on the soil of earth.”
—Henry David Thoreau (1817–1862)
