Radiocarbon dating of blackened grains from the site advantages of dating a married man
It has long been discussed, for example, whether the earliest plants taken under cultivation in some areas of the world were dietary items or used for nonfood purposes.
In sample 19, dated to 6970 grains exceed those of all modern wild beans studied.
The previous earliest record for but neither did they conform to a known wild species.
They almost certainly represent cultivars because they occur far outside the natural distribution of the genus in southern South America (15).
We cannot state with much precision how much of an individual's lifetime the tooth calculus that was studied represents.
Little information is available on the rate of calculus formation but because it accumulates over an individual's life if not removed, at least several years of diet is probably represented for each tooth studied.
The Late Pleistocene to Middle Holocene Ñanchoc preceramic culture is known from 46 sites in the Ñanchoc Valley, a tributary of the Zaña Valley located at 500 m above sea level on the lower western slopes of the Andes (1–7) (Fig. Recovered from hearths and floors in 13 excavated house structures dating from ∼10,100 to 5500 C yr B. The isolated teeth come from an estimated minimum of six to eight individuals, probably from both sexes; three complete individuals are also represented (Table 1).
