Quizplus · Accepted Answer

The brainstem is considered the oldest region of the brain in terms of evolutionary history. It controls basic functions such as breathing, heart rate, and digestion that are essential for survival and were present in early vertebrates. The limbic system and frontal lobes are more recent developments in evolutionary history and are associated with higher-level cognitive and emotional processing. The corpus callosum, while important for connecting the two hemispheres of the brain, is not considered to have an extensive evolutionary history.
