When you say that the number of drab females increase when the number of bright colored males increase, consider other factors. Is it possible that the number of drab females is related to the decreasing number of predators. It could be that these two factors are independent of one another, but caused by the same factor.
On slide 3, you stated that as "the brighter make guppies increase from 5 to 108 as the pools get darker". The turbidity of water decreases from 27.50 and 36.25 to 3.00 and 8.75, which means that as the brighter guppies increase, the water becomes clearer since the value is close to 0.
For the evidence slide, when you said "the pools get darker" did you mean that the pool becomes clearer due to the low turbidity levels present in pools further upstream?
I believe that your reasoning and claim would be better if you changed the wording of the pools getting darker because that is not supported by the actual evidence presented in the packet.
In your reasoning, are you stating that there is sexual selection because of the fact that the drab guppies can not be seen in higher turbidities, not because they are attracted to each other or both?
Your presentation adequately explained your claim. I thought it was clever how you chose to use two reasons for the changes in the trends in the colorization of guppies. However, you may want to check your spelling errors on the explanation slide.

Do you think there could have been sexual selection in the darker side of the river as well?
