How did the altithermal period change the cultures of early American Indian peoples in Oklahoma? Explain how changing temperatures affected society.

The correct answer to this open question is the following.

The Altithermal period changed the cultures of early American Indian peoples in Oklahoma in that higher temperatures made the weather change and grasslands spread over most of the Oklahoman territory. The eastern part of Oklahoma remained with woodlands. This grassland spread helped to attract big animals such as Buffaloes and other types of animals like rabbits, deers that could adapt to the climate conditions. Of course, this factor helped to attract Native American Indians because they could hunt those animals to feed their families. So yes, changing temperatures affected society and is a major factor to limit or attract people to one territory, depending on the highs and lows of climate conditions.
