"It is this evidence concerning the western contribution which persuaded workers to advocate the view that the Andronovo culture area was the original home of the Indo-Iranians, from where they marched into Iran and India as two separate groups by the end of the 2nd millennium B.C. or the beginning of the 1st millennium B.C.. The Andronovo hypothesis was nevertheless faced with a serious shortcoming from the very beginning. The cultures of the Timber-frame Andronovo circle took shape in the 16th or 17th century B.C., whereas the Aryans already appeared in the Near-East not latter than the 15th to 16th century B.C.... These regions contain nothing reminiscent of Timber-frame Andronovo materials; in fact, the latter could not have been there at so early a date."
