Unlike cattle and sheep, horses do appear in the North American fossil record and their story will be told in the next episode of the long-running ‘Nature’ series, set to air on February 23, according to an announcement posted earlier this week by Arizona PBS.
The extent to which the wild vs. feral debate will be considered is not known.
The remark about horses racing across the Pony Express trail may be a reference to the Onaqui Mountain herd, most of them removed from their Congressionally designated habitat last summer, in favor of privately owned livestock.
