Question:

Why do plants produce molecules that bind to human receptors? What are the odds that a plant will develop a signal receptor system that is compatible with humans?

Lectins:

Lectins are molecules that are found in plants and are present in most foods. They bind soluble carbohydrate groups on a variety of molecules, including glycoproteins and glycolipids. Plant lectins are generally harmless, but some, such as ricin, are highly toxic.
