Thousands of years of human breeding transformed wild species into the domesticated varieties we enjoy every year.
Most of these foods were originally found in the Americas.
The original domesticated carrots were purple. Carrots were bred to be orange by Dutch farmers in the 17th century, and then used as a political symbol of the ruling family - the House of Orange.
The ancestors of pumpkins were mainly eaten by mastodons and giant sloths - they were too bitter for smaller animals to stomach.
Turkeys were bred to have white plumage so their skin would be more uniform in color.
