25. If Ro = 2.5 a) the average newborn female can expect to produce 5 offspring in her lifetime b) every newborn female can expect to produce 2.5 offspring in her lifetime c) the population is in decline d) the average newborn male will produce 5 offspring, with r = 0.5 e) the population will grow until N =K 26. Suppose that an especially ignorant bird has never taken an evolutionary biology course, and never heard of or understood Hamilton's rule (very ignorant bird indeed): a) it will know who to direct altruistic help toward b) it is likely to think through its options for helping other individuals, and calculate degrees of relatedness, costs, and benefits of certain actions c) it will exhibit behaviors that in its ancestors successfully made Br-C> 0 d) it will give up in frustration and not be altruistic 27. Quickly changing biotic environments a) favor asexual reproduction b) favor developmental canalization c) favor phenotypic plasticity d) favor sexual reproduction e) probably both c and d are favored by rapidly changing biotic environments
