During the Paleolithic era, hunter-gatherer groups began to develop cultural traits. What was the most important influence on which cultural traits developed?

Climate shaped the resources available to Paleolithic groups, including the plants and animals they could rely on.

So the climate where the groups lived was the most important influence; ease of getting food mattered too, but it was strongly shaped by climate.
