Which of the following is true regarding senescence? Aging must be explained by different evolutionary forces among different species. Animals may vary in longevity, but the aging processes are similar. There is minimal variance in either longevity or the process of aging among animals.

Aging is a property of all animals that reach a fixed size at maturity, and the variations in life spans among different species are far greater as that among individuals from the same species: a fruit fly is ancient at 40 days, a mouse at 3 years, a horse at 30, a man at 100, and some tortoises at 150. (A) among different species are far greater as that among individuals from (B) among different species are far greater than that among individuals from (C) among different species are far greater than those among individuals of (D) between different species are far more than that between individuals of (E) between different species are greater by far than is that between individuals from

Which of the following has been proposed as an evolutionary explanation for senescence? (Select all that apply. HINT: the proposed explanations may not be generally considered correct) Group of answer choices Bergmann's rule Aging and death are adaptations for the good of the group Genes that cause senescence show antagonistic pleiotropy Hamilton's rule Kleiber's Law
