Present-day domestic goats may look humble, but they harbor more genetic diversity than any other livestock species. In fact, analyses of goats' mitochondrial DNA have shown that these animals evolved through five distinct maternal lines that spread from the Near East and central Asia across Europe.

A new study indicates that goats representing the earliest two of the five genetic lines inhabited the same location in southwestern Europe by about 7,000 years ago, only 3,000 years after the initial domestication of the animals in the Near East.

This ancient genetic diversity in a region far from the goat strains' origins reflects the long-distance transport of goats from the Near East by European pione
