Horse hooves gallop aeons ahead of the internet

Horses have been likened to "an ancient internet" for their role in early globalisation.

People on horseback and in wagons spread into new territories, new environments or along new trade routes, all of which brought about widespread and revolutionary shifts in culture. This is according to William T Taylor, author of a new book called Hoof Beats: How Horses Have Shaped Human History.

Taylor, an anthropologist at the University of Colorado Boulder, explains how horses and humans are entwined throughout history - and neither could have thrived without the other.
