The following graph depicts the performance of 3 bird species (green, red, blue) as a function of prey size. The sizes of prey that can be consumed by each species are a function of the bill size, which is under genetic control.
Choose among the following possible answers: stabilizing selection, disruptive selection, or direction selection.
(a) The green species would exert what kind of selection on the red species?
(b) The green and blue species together would exert what kind of selection on the red species?
(c) Draw the niche of a species that would exert disruptive selection on one of the other species shown on the graph.
(d) For one of the above examples (part a, b, or c), draw graphs of the type of data you would need to convince yourself that all three conditions for natural selection to occur could be met in the example. Be sure to label the axes on your graphs. You may draw a separate graph for each condition or use the same graph for multiple conditions, as appropriate.
