The mesencephalon gives rise to the midbrain and aqueduct of
the midbrian(cerebal aqueduct). Both the prosencephalon and rhombencephalon
develops in to the metencephalon and myelencephalon. The telencephalon develops into the cerebrum
and lateral ventricles. The diencephalon forms the thalamus, hypothalamus, and
epithalamus.

Answer:
directional selection
Explanation:
Directional selection is the most common type of natural selection and occurs when some individuals with characteristics favorable to the conditions of the environment in which they live, have survival advantages over individuals who do not have this advantage, who end up dying.
Imagine, for example, a graph showing the directional selection in the same species of moths. Moths of the same species have white and brown collations, in summer, brown moths can camouflage themselves on tree trunks, while white moths cannot and are easily captured by their predators, which means that the amount of white moths decrease. In this graph, the population of white moths would be at a minimum, at the same time that the population of brown moths would be at maximum.
However, with the arrival of the reverse, snow begins to cover the trees, allowing white moths to camouflage themselves more easily. The brown moths, then, are very exposed to predators, causing their population to reach the minimum while the population of white moths reaches the maximum.
