Because increased fecundity means increased fitness, we might expect to observe the evolution of ever-increasing fecundity, but this is not the case. which reason for lower-than-expected fecundity is plausible? group of answer choices a. increased fecundity leads to overpopulation and mass starvation, due to increases in individual fitness. b. all of the above are plausible reasons. c. fecundity evolves only until it balances mortality. d. while beneficial to the population or species, selection for increased fecundity is harmful to the individual. e. there are allocation trade-offs between fecundity and other traits.
