Hypothesis

This is our hypothesized evolutionary tree, showing 

how we predict our chosen species are related:

After observing the outward appearance of the flowers we used in our experiment, and considering which of them are annual and which are perennial, we drew this evolutionary tree. Looking at the way Millet and Snapdragon grow, that is, on a stalk holding many blossoms, and the fact that they are both annuals convinced us they should be next to each other on our tree. Our decision that irises are more closely related to snapdragon than to millet is mostly based off of our observation of the individual flowers, and the creatures who pollinate them. Irises grow a single flower from a single stem, but the flower that grows is much more similar in appearance to snapdragon than to millet. In addition, both Snapdragon and Iris have made complex adaptations to their flower structure and to their pollen in order to accommodate their insect pollinators, whereas Millet relies on birds to reproduce. We expect that under the microscopes, we will see more similarities in pollen type, number of apertures, and the surface texture of the pollen between Snapdragon and Millet and Snapdragon and Iris, than Millet and Iris.
