Theories Of Biological Aging
Vivian exhibits clear signs of aging in her fifties and dies at age 59. Why is it reasonable to question her doctor's assertion that her aging and death were determined strictly by genetic programming?
A
Evidence indicates that all aging is caused by wear and tear over time; therefore, Vivian's body must have been subjected to extreme wear and tear.
B
The doctor overlooks the obvious cause of death, which must be a disease process; an individual cannot die at age 59 without an active disease present.
C
Although the doctor is correct in asserting that genetics are programmed, he overlooks the likelihood that Vivian consumed an unhealthy diet.
D
It is highly unlikely that any single theory can fully explain the aging process; both genetics and physiological wear and tear play significant roles.
E
The doctor's assertion relies on debunked theories; evidence clearly demonstrates that genetics do not play a role in aging or death.
