Our civilizations are merging. The seeds from the lands of our heritage are being blown by the wind along the roads that we travel as we find new homelands. Our cultures are not static. They are constantly adapting to new environments and circumstances, merging like seeds and plants to form new environments and new cultures. Seeds and grains are the little parcels of embryonic food potential that have allowed civilisations to move across vast distances and thrive in remote and harsh terrain like central Australia. Humans have played a big role in transporting and dispersing seeds from their geographic origins. Patterns of seed dispersal reflect the intersection of cultures and their relationship to the natural world.
