// From the Episode
Dr. Corva described his work as being on the 'ethno' side of ethnobotany, focusing on human communities and oral histories rather than pure plant science. Mojave Richardson emphasized that California's role as the cannabis epicenter emerged because 'the fruits and nuts brought the seeds' — countercultural migrants brought genetics from their home states and international travel. The discipline recognizes that clone-only cultivars represent narrow genetic snapshots of small insular breeding communities.
