The chart below is a taxonomic key for the fictitious insect genus Problematica.
A student has been asked to identify the following insect specimens.
Part A: Using the dichotomous key above, provide the scientific name for each of the insect specimens A-D.
Part B: For #5 in the key above, provide a suggestion for a way that the two remaining insects, specimens E and F, might be described to ensure they are correctly identified.

In an animal population, the physical appearance of males and females can be noticeably different. As shown by the picture above, male white-tailed deer (Odocoileus virginianus) are easily recognized by the presence of antlers on their heads. Female white-tailed deer, on the other hand, do not grow antlers. Using the white-tailed deer for your example, describe how the mechanism of natural selection may have led to the evolution of antlers ONLY for males in a white-tailed deer population.
