Discussion Post
This discussion provides you with some data about four pools of guppies. These pools have different turbidity (i.e. cloudiness), make-up of predators, depths, locations, numbers of guppies, and contain bright or drab-colored male guppies. Your goal is to first observe the data given about the pools and note any patterns you see that might relate to the color patterns of the male guppies.
Selection pressures are an aspect of the environment that causes a change in characteristics over time. Then you will decide which of the selection pressures on the male guppies have resulted in the variations in color patterns you see in the data. The data you need for this assignment is posted in D2L titled Data for Evolution by Natural Selection Discussion.
Step I: Observation
i. A short summary, approximately a paragraph, of Table 2.1. Try to give a concise (short) but rich description of each of the four guppy pools.
ii. A short summary, approximately a couple of sentences, of Tables 3 and 4. These tables discuss different characteristics related to guppy mating.
Step II: Draw a Conclusion
i. What selection pressures caused the variation in the color pattern of male guppies? Support your claims with evidence.
ii. Is it better to be bright or drab if you are a male guppy? Support your claims with evidence.
