Phylogenetics of Cannabis
Phylogenetics of Cannabis is the reconstruction of the evolutionary relationships of the genus Cannabis from molecular data. It addresses three questions: the placement of Cannabis among the genera of the family Cannabaceae, the genetic structure within the genus, and the genomic signatures left by domestication. Successive methods resolve these relationships at different depths, and the picture has sharpened as whole-genome sequencing has replaced the biochemical and marker-based approaches used earlier.
Molecular evidence informs the long-running dispute over how many species the genus contains, but has not settled it; recent genomic reviews lean toward a single species while treating the question as open, and the rank debate itself is covered in Cannabis taxonomy. How much phylogenetic structure can be recovered is limited by two features of the plant: the genus is fully interfertile, so gene flow between lineages is easy, and four decades of intentional hybridisation between drug-type populations have overwritten much of the older structure in cultivated material. read more →

Cannabis eradications
We are witnessing the rapid disappearance of traditional cultivation knowledge and genetic diversity in cannabis. These landrace populations represent thousands of years of natural and human selection, containing unique genetic traits and chemical profiles. Systematic documentation and conservation efforts can serve as a bridge, preserving irreplaceable genetic heritage while supporting traditional communities and advancing our understanding of this remarkable plant.
