It has been hypothesized that fungi colonized land before plants. If true, then what does this mean regarding animals? Explore the relationships between plant, fungi, and animals and discuss why this hypothesis may be supported or rejected. What evidence would need to be found to support it? Why is it unlikely that we will be able to categorically dismiss it? Be sure to back up your claims with peer-reviewed, primary scholarly sources.

Endophytic fungi are required by gametophytes of all the "primitive" vascular plants. If the endophytic fungi is not present in the soil, the gametophyte plant will not grow. Why would such a condition develop? Are there any advantages to this absolute requirement for gametophyte development? Explain.
