Giraffes having increasingly longer necks over time.
Reason: natural selection produces population-level change across generations by favoring heritable traits that increase survival or reproduction. The giraffe example describes an evolutionary change in a lineage; the other choices describe a single defect, a likely maladaptive trait in that environment, or a trait not clearly shown to be the result of selection.
