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.

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).
