For most of human history, horses were seen as prey to be hunted for sustenance. During the late Pleistocene, around 55,000 years ago, Neanderthals scavenged off of horse carcasses and made occasional kills of their own.
There was also a rise in the number of horses slaughtered - up from 3,500 in 2008 to over 24,000 in 2012. It dropped to 10,000 in 2013, but the report says that may have been partly as a result of stricter controls following the horse meat scandal. This article was amended on 12 June.
