e. group survival . b. an exaptation . Which of the watch conditions would most probably lead to an increase in the frequency of an altruistic behavior in a population ?
a. Groups that differ in terms of altruistic and selfish genotypes have derived function reproduction or survival.
bel. The altruistic behavior benefits the population.
c. The rate of extinction of the selfish genotype is senior high school.
d. There is a gene hang among populations.
e. The beneficiaries of the behavior are related to the individual acting it . e. The beneficiaries of the behavior are related to the individual perform it . An experiment shows ( 1 ) that the size of a population may decline as a solution of natural survival, even as person organisms become fit and ( 2 ) that selection for larger groups opposes the consequences of individual survival. These observations provide evidence for
a. the influence of altruistic traits.
b. the work of group survival.
c. the effects of individual survival.
d. Both boron and cytosine
e. All of the above d. Both b and c Which of the following would be the best way to test whether larger body size in amphipods is an adaptation to risk of depredation ?
a. Correlate body size with predation risk across a number of closely relate species, independent of phylogenetic relationships.
b. Correlate body size with depredation risk across a number of close related species, taking into report phylogenetic relationships.
c. Expose two species that differ in torso size to predators and compare their survivorship.
d. Expose all of the close relate species to predators and compare their survivorship.
e. Correlate body size with other possible antipredator traits, such as armor or swimming accelerate . b. Correlate consistency size with depredation hazard across a number of closely relate species, taking into score phylogenetic relationships . Species choice occurs when there is a correlation coefficient between some trait and the rates of two processes : _______ and _______.
a. survival ; reproduction
b. geological duration ; geographic compass
c. speciation ; extinction
d. fitness ; heritability
e. sexual replica ; asexual reproduction c. speciation ; extinction not all traits are adaptations. Which of the postdate may besides explain the development of a particular trait ?
a. It may be a necessity consequence of physics or chemistry.
b. It may have evolved by genetic drift preferably than by natural choice.
c. It may have evolved because it was correlated with another trait that conferred an adaptive advantage.
d. It may be a consequence of phylogenetic history.
e. All of the above e. All of the above

Which of the comply conditions can not cause the development of an adaptation ?
a. environmental change that does not threaten extinction
boron. The superiority of new mutations to any preexistent genic variations in an unchanging environment
c. Future extinction of a population
d. Environmental change that reduces population size
e. none of the above can cause the evolution of an adaptation . c. Future extinction of a population Which of the follow statements about adaptations is fake ?
a. They enhance seaworthiness.
bacillus. They evolve through natural excerpt.
c. They perform a routine.
d. They arose when the current function originate.
e. They are developed by individuals in response to the needs of the individual . e. They are developed by individuals in response to the needs of the individual . A feature that reduces the seaworthiness of an individual but benefits the population or species
a. can not evolve by individual selection.
b. could evolve by group selection.
c. would decline in frequency among early nonaltruistic phenotypes.
d. All of the above
e. none of the above d. All of the above Alarm calls by ground squirrels alert other flat coat squirrels to danger, but they draw attention to the caller and expose it to increased gamble of predation. such altruistic behavior is best explained by the phenomenon of
a. selfish genes.
b. group choice.
c. individual choice.
d. kin survival.
e. exaptation d. kin choice . Which of the take after traits can be thought of as a preadaptation for the equate function ?
a. Snake skull bones → swallowing prey
b. Kea ’ s peck → piercing skin
c. Orchid bloom form → pollination
d. Spider intimate suicide → fertilization success
e. Ant concerted behavior → queen generative achiever b. Kea ’ s beak → cutting skin Which of the surveil is defined as any coherent difference in fitness among phenotypically different classes of biological entities as a consequence of competition for mates ?
a. generative achiever
bacillus. lifelike selection
c. Sexual choice
d. Individual excerpt
e. meiotic drive

c. Sexual survival The fitness of a biological entity is
a. the mutant in the number of offspring produced as a consequence of competition for mates.
b. any consistent difference in generative success among phenotypically different classes of organisms.
c. its survival rate.
d. its average per caput pace of increase in numbers.
e. its physiologic discipline . d. its median per caput rate of increase in numbers .
