How to interpret past human mobility patterns

New paper (behind paywall), Interpreting Past Human Mobility Patterns: A Model, by Reiter and Frei Eur J Archaeol (2019).

Interesting excerpts (modified for clarity; emphasis mine):

Present investigations of mobility can be divided into two main groups: 1) individual mobility, and 2) group mobility.

Research approach

(…) it is arguable that, ‘the reality of a mobile existence is far more complex than the ordering principles used to describe it’ (Wendrich & Barnard, 2008: 15). It seems that the most accurate means of modelling mobility is through a thorough examination of a variety of phenomena in combination with archaeological context.

Open access Genomic and Strontium Isotope Variation Reveal Immigration Patterns in a Viking Age Town, by Krzewińska et al., Current Biology (2018).

Interesting excerpts (emphasis mine, some references deleted for clarity):

The town of Sigtuna in eastern central Sweden was one of the pioneer urban hubs in the vast and complex communicative network of the Viking world. The town that is thought to have been royally founded was planned and organized as a formal administrative center and was an important focal point for the establishment of Christianity [19]. The material culture in Sigtuna indicates that the town had intense

Improving environmental conditions favoured higher local population density, which favoured domestication

New paper (behind paywall) Hindcasting global population densities reveals forces enabling the origin of agriculture, by Kavanagh et al., Nature Human Behaviour (2018)

Abstract (emphasis mine):

The development and spread of agriculture changed fundamental characteristics of human societies1,2,3. However, the degree to which environmental and social conditions enabled the origins of agriculture remains contested4,5,6. We test three hypothesized links between the environment, population density and the origins of plant and animal domestication, a prerequisite for agriculture: (1) domestication arose as environmental conditions improved and population densities increased7 (surplus hypothesis); (2) populations needed domestication to
