Teosinte, a Mexican grass, is considered a historical precursor plant to modern corn. The teosinte ear has only between 5 and 12 kernels, but these plants are highly resistant to insect pests and to both viral and fungal diseases of corn. From a production standpoint, teosinte seems worthless compared to the high-yield varieties of corn currently grown as vast monocultures. How do monocultures affect agrobiodiversity? In this context, what is the value of teosinte to agriculture in the long term?
