Mice as stowaways? Colonization history of Danish striped field mice

http://rsbl.royalsocietypublishing.org/content/13/7/20170064

"Abstract

Species from the steppe region of Eastern Europe likely colonized northwestern Europe in connection with agriculture after 6500 BP. The striped field mouse (Apodemus agrarius Pallas, 1783), is a steppe-derived species often found in human crops. It is common on the southern Danish islands of Lolland and Falster, which have been isolated from mainland Europe since approximately 10 3008000 BP. Thus, this species could have been brought in with humans in connection with agriculture, or it could be an earlier natural invader. We sequenced 86 full mitochondrial genomes from the northwestern range of the striped field mouse, analysed phylogenetic relationships and estimated divergence time. The results supported human-induced colonization of Denmark in the Subatlantic or Subboreal period. A newly discovered population from Central Jutland in Denmark diverged from Falster approximately 100670 years ago, again favouring human introduction. One individual from Sweden turned out to be a recent introduction from Central Jutland."

"The greatest haplotype diversity is observed in Pakistan and northern India where all four sub-groups are present but CAS-2 and CAS-3 are dominant"

Interesting how we can trace human movements through pests as well.

It's just like passenger migration lists.
Ancestors usually traveled with family, so if your direct ancestor has common names, but a sibling has a rare first name, or married and came with the family group, you can track them that way.
Humans brought some of their farm and burden animals, pets, vermin, diseases, and other fellow travelers on their journeys.

There is one proviso that needs to be discounted.
They may have come with trade.
What is indisputable is that there is SOME sort of physical connection.

Just not the TARDIS.
