Explanation:
Stabilizing selection is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value. This occurs when the environment is stable and consistent, and selection pressures eliminate individuals on the extremes of the trait distribution.
In this scenario, the weight of a newborn ranges from 2 to 5 kg, with a survival rate that varies based on the weight. The survival rate is highest for newborns with an average weight between 3 to 3.3 kg, which suggests that the population is stabilizing on this trait value.
Furthermore, the survival rate is much lower for newborns with weights from 2 to 2.5 kg or 4.5 to 5 kg, indicating that selection pressures are eliminating individuals on the extremes of the trait distribution.
Therefore, the type of selection process that is taking place in this scenario is stabilizing selection.
