“…aDNA can help elucidate the genetic relationships between prehistoric individuals, past population movements or interactions, and changes in genetic diversity over time (e.g., O'Rourke et al, 2000a;Kaestle and Horsburgh, 2002;Kemp et al, 2007;Shook and Smith, 2008;Keyser et al, 2009;Rasmussen et al, 2010). Genetic data from ancient remains can also be used to reconstruct the kinship systems, mating patterns, social structure, and burial practices of ancient populations (e.g., Keyser-Tracqui et al, 2003;Mooder et al, 2005;Bolnick and Smith, 2007; Haak et al, 2008).While numerous methods have been developed for extracting aDNA from skeletal remains, virtually all protocols require the destruction of some portion of the specimen, usually by powdering part of a tooth or bone (O'Rourke et al, 2000b;Kaestle and Horsburgh, 2002). Because this destructive analysis permanently removes skeletal material and may make other analyses more difficult or impossible (i.e., if skeletal material is damaged or exhausted in attempts to isolate DNA), museums may be unwilling to permit aDNA analysis of the unique human remains in their collections.…”
