L. siceraria or bottle gourd, thought to have originated in southern Africa, was brought to Europe and the Americas very early in history, being found in Peruvian archaeological sites dating from 13,000 to 11,000 BC and Thailand sites from 11,000 to 6,000 BC. A study of bottle gourd DNA published in 2005 suggests that there are two distinct subspecies of bottle gourds, domesticated independently in Africa and Asia, the latter approximately 4,000 years earlier. The gourds found in the Americas appear to have come from the Asian subspecies very early in history, although a new study now indicates Africa. The archaeological and DNA records show it is likely that the gourd was among the first domesticated species, in Asia between 12,000 and 13,000 years before present, and possibly the first domesticated plant species.
