Genetic diversity of crops

Photos:
Different potato varieties from Peru and from a grocery store in Germany are used as examples of genetic diversity and genetic poverty of crops.

In Peru there are several thousand different varieties of potatoes. Many of them were forgotten, but today they are increasingly being grown again. The potatoes available in Europe originate from a few varieties that explorers brought back from their journeys to the New World in the 16th century.

Information and ideas:
Can be used as an introduction to the discussion about the huge significance of genetic diversity for life on our planet. A comparison can be made with the species diversity of other crops, such as corn or soy. How can historical famines, such as the Irish potato famine in the 19th century, be explained in terms of the genetic poverty of crops?
