From phys.org: Ancient mice teeth show settled villages made ecological impact long before agriculture.

Long before the advent of agriculture, hunter-gatherers began putting down roots in the Middle East, building more permanent homes and altering the ecological balance in ways that allowed the common house mouse to flourish, new research in the Proceedings of the National Academy of Sciences indicates.

“The research provides the first evidence that, as early as 15,000 years ago, humans were living in one place long enough to impact local animal communities—resulting in the dominant presence of house mice,” said Fiona Marshall, study co-author and a professor of anthropology at Washington University in St. Louis. “It’s clear that the permanent occupation of these settlements had far-reaching consequences for local ecologies, animal domestication and human societies.” [continue]
