Early Horse Domestication Evidence in Kazahkstan

Evidence from soil suggests that people were relying on domesticated horses for survival more than 5,000 years ago.

Archaeologists have had trouble figuring out when horses were first domesticated because the first riders and herders did not use iron bits or fittings. The leather and rope tools they used have perished over time. However, a team working in Kazahkstan has used soil chemistry to identify areas where ancient horses manured the soil.
