Biology: Supporting the Energy of Large Brains

Large Brains”

Topic 3 [article]: Supporting the Energy Needs of a Large Brain. As discussed in the article by Zimmer (3)*, brain tissue is energetically expensive. For a species to evolve a large brain, it may need to make certain adjustments to ensure that enough energy is available to support brain function. Zimmer discusses various hypotheses about such adjustments in the human line of descent. Explain one of these adjustments.
