The type of selection that can occur when individuals with phenotypes at the upper and lower ends of the curve have higher fitness than individuals near the middle is Disruptive selection.

Here's a step-by-step explanation:

1. In biology, natural selection is a process where organisms better adapted to their environment tend to survive and produce more offspring. This process leads to evolution.

2. There are three types of natural selection: directional, stabilizing, and disruptive.

3. Directional selection occurs when one extreme phenotype is favored over other phenotypes, causing the allele frequency to shift over time in the direction of that phenotype.

4. Stabilizing selection occurs when the intermediate phenotype is favored over the extreme phenotypes. This reduces genetic diversity and maintains the status quo.

5. Disruptive selection, on the other hand, occurs when extreme phenotypes are favored over intermediate phenotypes. This can result in two new species if the population is separated into two distinct groups.

6. Therefore, when individuals with phenotypes at the upper and lower ends of the curve have higher fitness than individuals near the middle, it is an example of disruptive selection.
