Original Post – Due two days before the due date.

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 one: Observation

1. Write 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.

2. Write a short summary, approximately a couple of sentences, of Tables 3 and 4. These

tables discuss different characteristics related to guppy mating.

Step Two: Draw a Conclusion

1. What selection pressures caused the variation in the color pattern of male guppies?

Support your claims with evidence.

2. Is it better to be bright or drab if you are a male guppy? Support your claims with

evidence.

Respond to your peers – Due by the due date.

NOTE: Only those student who have submitted a main post two days before due date are eligible to respond to peers.

You must start a thread before you can read and reply to other threads

Go through the majority of the posts and respond to two other students. Both of your

responses should be grammatically correct, well thought out, and further the

discussion. Some common ways to further a discussion are to ask a question, share

something related to the topic, or expand on a topic. Responses should be approximately a

paragraph in length.

For example, in this topic, you might note similarities and differences in your observations.

You may also find you disagree with a peer’s assessment of what causes the color variations

or the benefit of being bright or drab. Remember to always support your claims with

evidence!
