“We unraveled the geographic origin of the cultivation of cannabis (East Asia), the date (early Neolithic), and the presence of a cannabis genetic lineage unknown to date, distinct from the one that gave rise to the hemp and marijuana varieties distributed worldwide, and probably still similar to the early domesticated common ancestor of all these lineages” . . .
"Though previously a matter of debate, cannabis researchers have largely reached consensus that cannabis is comprised of just one species—Cannabis sativa—and this research corroborates that idea. So if you hear someone refer to indica, they’re still talking about a Cannabis sativa plant."

And the study: Large-scale whole-genome resequencing unravels the domestication history of Cannabis sativa
