“…In recent decades, advances in mobility research have created a broader understanding of how mobility—or potential mobility—functions in an increasingly connected world (see discussion of push/pull in Heberle, 1938; Lee, 1966; cost/benefit in Sjastaad, 1962; and ‘motility’ in Kaufmann et al, 2004). New methods in the field of isotopic tracing, such as the analysis of hair and fingernails, micro-sampling of multiple skeletal elements as well as the consecutive analysis of molars, has enabled scholars to create high-resolution timelines for individual human movements (Font et al, 2012; Tipple et al, 2013; Knipper et al, 2014; Frei et al, 2015a, 2015b, 2017; Scharlotta, 2018). Studies of various cases of single individual mobility timelines can be combined with other group analyses, thereby allowing archaeology to gain a better handle on the complexity of the networks connecting human biology, ethnicity, culture, and heritage (Haak et al, 2008; Knipper et al, 2017).…”
