1. Discuss what you think might happen to this population of birds over many generations with respect to the three different types of selection (directional, stabilizing, and disruptive selection). Formulate your argument, including backing evidence, for which of the three types of natural selection the birds will likely undergo and debate and defend your thoughts with a classmate.

stabilizing selection

Explanation:

Both directional and disruptive selection are extreme phenotype selections, i.e. against the average phenotype. Stabilizing selection, like the adjective already explains, is a type of natural selection that stabilizes on a non-extreme trait or mean average. A good example is human birth weight. The extreme cases (very light or very heavy) have less chance to survive and to reproduce.
