Solution
The main, or central, idea of the passage is:
**As early humans developed agriculture, their bones changed significantly.**
This statement encapsulates the overall theme of the passage, which discusses how the transition from a hunter-gatherer lifestyle to an agricultural one led to notable changes in the human skeleton, particularly in the jaw and other bones. The other option, while true, is more specific and does not capture the broader transformation described in the passage.

As early humans settled into agriculture, their bones adapted to a softer diet, leading to a smaller jaw and lighter bones. This shift highlights the profound impact our diet has on both our physical structure and lifestyle. Imagine a time when humans roamed the earth hunting mastodons and foraging for wild berries! The transition to agriculture not only changed how they sourced food but also marked the beginning of communities, trade, and modern civilization. So, grab a fork and appreciate those plant-based dishes – they shaped our ancestors just as they’ve shaped us!
