“Tarnita’s Termites, Pacific Lampreys, and Large Brains”
This week our discussion is focused on animal evolution. For your primary post, respond to one of the following three topics. Also, please reply to at least one fellow student on any topic.
: Population Distribution of Termites in a Savanna. Watch the video (1) describing Corina Tarnita’s research on the spacing of termite mounds in savanna ecosystems, and then address the following:
: Pacific Lampreys. Watch the video about Pacific Lampreys (2)*, then address the following:
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.
