Natural selection acts on the distribution of traits. When graphed, natural selection shifts the graph away (new population) from its original shape (original population). The original graph that serves as a baseline for the shifts in traits caused by natural selection is referred to as what type of distribution and is represented by what type of curve? a.) Normal distribution/Spiked-curve
b.) Abnormal distribution/Bell-curve
c.) Normal distribution/Bell-curve
d.) Abnormal distribution/Spiked Curve
