Based on Darwin's ideas of descent with modification and natural selection, observation would best support the idea increased competition causes changes in a species ?
A population of rattlesnake goes extinct as the water resources in their environment dry up during an extreme, prolonged drought
A population of frogs develop greener skin after a hurricane blows away the white flowers the environment
A population of artic foxes develop a brown fur color as warmer temperatures reduce the number of days of snowfall in the area
A population deer show an increase in antler size over time, which allows them to obtain more mates during mating season
Primates are examples of: a. density-dependent species b. density-independent species c. r-selected species d. K-selected species
Two different species cannot occupy the same niche in the same geographic area. If they do they will compete with one another for the same food and other resources. Eventually, one species will out compete the other. This is an example of natural selection.
A) True
B) False

Group of answer choices choices made by plant and animal breeders possession of adaptations developed through use possession of inherited adaptations that maximize fitness lack of competition within the speciesarrow_forward
- Approximately 14,000 years ago, the climate in North America began to warm rapidly. At the same time, human hunters migrated to the continent. Which of these most likely resulted from a combination of these two factors? an increase in the rate of large mammal extinctions a reduction in the rate of species change an increase in the amount of interspecies cooperation a reduction in the total number of small parasitic insectsarrow_forwardMany species of animals make alarm calls, which warn others in their group that a predator is approaching. Alarm calls also attract the atten- tion of the predator, making it more likely that the individual making the call will be eaten. Why might natural selection favor the evolution of alarm calls in a species? How might you test that hypothesis?arrow_forwardWhich of the following would likely not be a result of character displacement? A: The competition between 5 beetle species living in the same area is lessenedB: One of the four bird species on an island goes extinctC: Coevolution of plants and pollinatorsD: Two lizard species in the same area evolve the ability to feed on different insectsarrow_forward
- Given your knowledge of how predators and resources can affect life history traits, hypothesize how the four combinations of high resources, low resources, predator presence, and predator absence would affect the size at maturity of a prey species.arrow_forwardYou arrive on an island that has not been previously studied by biologists. You discover a number of species of snails that bright colored shells and bodies with black bands. What type of species interaction is most likely to be the cause of natural selection for these colors? Group of answer choices a. predation b. competition c. mutualism d. commensalismarrow_forwardMembers of some species will sound warning calls when they notice predators even though this increases the likelihood the predator will find the individual that provided the alarm. The evolution of such behaviors provides evidence for which hypothesis? A. Evolution selects behaviors that increase the ability of individuals in a species to camouflage. B. Evolution selects behaviors that increase the likelihood that individuals in a species will reproduce. C. Evolution selects behaviors that increase the the likelihood that individuals in a species that share similar genes will survive and reproduce. D. Evolution selects behaviors that increase the likelihood that individuals in a species that share similar genes will migrate.arrow_forward
- Many species of birds have elaborate mating rituals that include bird calls, nest construction, and courtship displays. A researcher is comparing two populations of birds with similar morphology that live in similar niches. Male birds in one population build a nest before attempting to court a female, while males in the other population build the nest in cooperation with the female. Is it likely the researcher will classify these birds as the same species?arrow_forwardA population has several generations of random mate choice followed by a generation of nonrandom mate choice. The effect of this generation of nonrandom mate choice is ____. a new evolutionary pattern due to nonrandom mate choice would begin equilibrium (no change between the random generations and the nonrandom generation) a reversal of the evolutionary pattern set by random generations due to a generation of nonrandom mate choicearrow_forwardThe graph in Figure 3 represents the beak sizes of the offspring of the birds that survived the drought of1977. (The survivors were represented by the black bars in Figure 2, and this graph shows the beak depth distribution of their offspring in 1978.) Explain the observed change in beak characteristics using the following concepts in your answer: competition, survival of the fittest, inheritance.arrow_forward
