BioEE1780 Evolution and Biodiversity Today’s lecturer: Cole Gilbert Lecture 17: Oct. 5, 2011 Diversity 6 page -1 Fungi: Those magical molds and mushrooms Readings: Life, 9 th ed. Chapter 30 In this lecture we will go back to the basal radiation of the eukaryotes and continue exploring the last clade, the Unikonts, which will be the focus of the remaining diversity lectures this semester. A few weeks ago, we introduced this early radiation: Chromalveolates, Plants, Excavates, Rhizaria and Unikonts. The first four groups are sometimes, although not in your text, put together in a group called Bikonts, because when they have flagella, they have two of them (bi = two, kontos = pole). The Unikonts, in contrast, extend only a single “pole” or flagellum, if they have one at all. The Unikonts are split into two groups. The first is Amoebozoa, the slime molds, which have their flagellum at the anterior end and pull themselves through the water like all the other eukaryotic groups we have discussed so far. The other group is the Opisthokonts, which includes animals and
