An Asian origin for a 10,000-year-old domesticated plant in the Americas

New genetic and archaeological approaches have substantially improved our understanding of the transition to agriculture, a major turning point in human history that began 10,000-5,000 years ago with the independent domestication of plants and animals in eight world regions. In the Americas, however, understanding the initial domestication of New World species has long been complicated by the early presence of an African enigma, the bottle gourd (Lagenaria siceraria). Indigenous to Africa, it reached East Asia by 9,000-8,000 before present (B.P.) and had a broad New World distribution by 8,000 B.P. Here we integrate genetic and archaeological approaches to address a set of long-standing core questions regarding the introduction of the bottle gourd into the Americas. Did it reach the New World directly from Africa or through Asia? Was it transported by humans or ocean currents? Was it wild or domesticated upon arrival? Fruit rind thickness values and accelerator mass spectrometer radiocarbon dating of archaeological specimens indicate that the bottle gourd was present in the Americas as a domesticated plant by 10,000 B.P., placing it among the earliest domesticates in the New World. Ancient DNA sequence analysis of archaeological bottle gourd specimens and comparison with modern Asian and African landraces identify Asia as the source of its introduction. We suggest that the bottle gourd and the dog, two "utility" species, were domesticated long before any food crops or livestock species, and that both were brought to the Americas by Paleoindian populations as they colonized the New World.

BP is Before Present. So 8000-9000 BP is roughly 6000-7000 BC. At least that is better on my eyes than the screwy BCE that some pc scholars have used.

Yes, since this is the year of Our Lord Jesus Christ 2005, he's trying to say circa 7,000 to 6,000 before Christ.

it reached East Asia by 9,000-8,000 before present (B.P.)

What present?

A Christmas present?

I remember seeing B.P. in museum exhibits long before B.C.E. started to be more widely used by the politically correct crowd.

It doesn't work well when you get down to historic times where more exact dating is possible...if you expressed the date of the battle of Marathon in B.P. terms you'd have to revise the number every year.

Actually B.P. has a base timeline...

I believe it is 1950 A.D. ( or C.E., or whatever )

Just adding this to the GGG catalog, not sending a general distribution, as we've had a similar topic.

I think Drammach may right about the 1950 baseline for B.P. in RC dating. Rings a bell anyway. Bibby pioneered his method of RC dating about 1950.

To all -- please ping me to other topics which are appropriate for the GGG list. Thanks.
