How did the end of the altithermal period affect Archaic Indian cultures in Oklahoma? A. It allowed for more megafauna to migrate to eastern Oklahoma. B. It allowed for increased development in Oklahoma. C. It allowed for fewer game herds to come to Oklahoma. D. It allowed for mass migration from Asia to America.

The correct answer is B.

Explanation:

The Alithermal Period refers to a period which spans 50 decades. It is characterised by protracted harsh climatic conditions especially heat, and aridity. When the period eased up for a more friendly climate, the population of the region naturally expanded by immigration. This translated to more permanent settlements. As the population increased, so did the development in the region.
