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.
(…) 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.

A new paper has appeared at BioRxiv, The Genomic Health Of Ancient Hominins (2017) by Berence, Cooper and Lachance.
Important results are available at: http://popgen.gatech.edu/ancient-health/.
While the study’s many limitations are obvious to the authors, they still suggest certain interesting possibilities as the most important conclusions:
- In general, Genetic risk scores (GRS) are similar to present-day individuals
- Genomic health seems to be improving over time
- Pastoralists could have been healthier than older and modern populations
Some details and shortcomings of the study (most stated by them, bold is from me) include:
- Allele selection: only some of the known
