The figure below shows the per capita mortality rates for three different vertebrate species. How would the graphs look like in the absence of senescence?
The human females are represented by the lowest line on the graph, the chimpanzee females are represented by the middle line on the graph, and the Harbor porpoise is represented by the top line on the graph. a. They would rise linearly with age. b. They would be parallel to the x-axis. c. They would continue to show elevated rates at an early age, but then bottom out and parallel the x-axis. d. This cannot be confidently determined as the mortality rate mirrors both extrinsic mortality and senescence.
