Question

human babies are typically born within a very narrow range of weight. babies that are too heavy or too light are less likely to survive. in terms of natural selection, this is an example of ______. a artificial selection b disruptive selection c directional selection d stabilizing selection

Explanation:

Stabilizing selection favors intermediate traits (here, average birth weight) by reducing survival of extreme traits (too heavy or too light). Artificial selection is human-driven, disruptive selection favors extremes, and directional selection shifts toward one extreme—none match the scenario except stabilizing selection.

Answer:

d. stabilizing selection
