If extrinsic mortality is high,

A) selection will act more strongly against mutations that negatively affect organisms late in life than those that do so early in life.
B) selection will act equally strongly on mutations that negatively affect organisms early in life and late in life.
C) organisms are likely to age more rapidly than if extrinsic mortality were low.
D) a and c
E) b and c

Extrinsic Mortality

The death rate from external factors, outside the organism's control, such as predation or accidents, as opposed to intrinsic factors like aging.

Mutations

Permanent alterations in the DNA sequence of an organism's genome, which can lead to diversity within species and potentially new species over time.

Aging

The complex biological process of getting older, characterized by a gradual decline in physical and cognitive functions.

  • Apply evolutionary theory to explain the mechanisms and outcomes of life history traits, including sex ratios and extrinsic mortality effects.
