Imagine that a species of fish used to be a broadcast spawner (producing many eggs that then get no subsequent parental care) but has evolved to be a mouth brooder (holding the eggs in the parent’s mouth until they hatch and then caring for the young for a while). We would expect the survivorship curve of this species to:

A. shift from Type I to Type II or III.
B. shift from Type II to Type I.
C. shift from Type III to Type I or II.
D. shift from Type II to Type III.
E. vary unpredictably.
