To add to this: Don't forget that all of our seeds today are the result of centuries of man-made breeding and selection processes. Mankind did selection and cultivation to achieve wanted properties (higher yields, resilience against plagues/insects, taste properties etc.) and todays strands of seeds are the result of this breeding - the value cannot be stressed enough. Best example is the grapefruit, a fruit that did not exist before the 18th century at which point it was the result of a cross-breed between an orange and a pomelo strain. It was deemed tasty, and that is the only reason why we still have it today.
