Adam Walton finds out all about camels, llamas, alpacas, vicunas and guanacos in this, the UN International Year of Camelids.

We learn about the evolutionary history of camels with Dr Pablo Orozco Ter Wengel from Cardiff University.

Head of the Pwllpeiran Upland Research Centre, Professor Mariecia Fraser, explains why there are alpacas in Wales.

Plus we head to Chester Zoo to meet two Bactrian camels, Sparky and Mei-Li.
