In the survivorship curve shown in the figure, imagine an early acting mutation that increases survivorship between days 0 and 30 and a late-acting mutation that increases survivorship between days 150 and 180. Natural selection will act

The survivorship curve shown is a Type I curve, where most individuals survive to old age and then experience a rapid decline in survivorship. The mutations that increase survivorship between days 0-30 and days 150-180 would both impact the initial portion of the survivorship curve, where most mortality occurs. Therefore, the early-acting mutation that affects survival early in life would have a larger impact on overall survivorship and would be subject to stronger selection. Additionally, the late-acting mutation that affects survival later in life would have less impact on overall survivorship since there are fewer individuals remaining at that stage.
