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)

    You must train the children to their studies in a playful manner, and without any air of constraint, with the further object of discerning more readily the natural bent of their respective characters.
    Plato (c. 427–347 B.C.)

    The price of hating other human beings is loving oneself less.
    Eldridge Cleaver (b. 1935)

    The best thing about the sciences is their philosophical ingredient, like life for an organic body. If one dephilosophizes the sciences, what remains left? Earth, air, and water.
    Novalis [Friedrich Von Hardenberg] (1772–1801)
