Question

Quizplus · Accepted Answer

This theory suggests that our hunter-gatherer ancestors needed to store fat because food was not always readily available. Therefore, over time, humans developed genes that allowed them to store fat for times of scarcity. However, in modern times, food is abundant, and we can easily consume more calories than we need, leading to obesity.
