Students have asked these similar questions
What is Allopatric speciation?
A) When a population is separated from the main group by a barrier and becomes a new species
B) When a population mutates into a new species
C) When a population develops into a new species without any physical barriers to isolate them
If a geographic barrier is removed and the two reunited populations intermingle and breed, what attributes must the offspring have in order for the two populations, according to the biological species concept, to be considered still the same species?
What is the ecological definition of a species?
A) A group of individuals that can breed and produce viable offspring
B) A group of interbreeding individuals that share the same environment
C) A group of individuals that share a common ancestor

- If the two populations in question 2 are determined to still be the same species, did allopatric speciation occur?arrow_forwardWhen the isthmus of Panama (land bridge that connects north and south America) arose about 3 million years ago, it caused species of fish to diverge into sister species located in either the caribean or pacific ocean. Why did they form separate species? A) Because this is an example of sympatric speciation B) Because the tides are different on each side of the land bridge C) Because different predators in each ocean caused the populations to diverge D) Because the populations were reproductively isolatedarrow_forwardWhy might captive-breeding programs that reintroduce species into natural environments fail?arrow_forward
- n which situation would it make sense to use the morphological species concept? When you are able to collect data about how individuals in your study use their habitat, but you are unable to determine if they interbreed When working with fossils from extinct organisms When you only have genetic data about each organism in your study When you are not able to collect data about how individuals in your study use their habitat, but you are able to collect reproductive dataarrow_forwardHow is sympatric speciation different from allopatric speciation? Group of answer choices Allopatric speciation requires a geographic barrier, while sympatric speciation occurs in one place Allopatric speciation results in hybrids, while sympatric speciation does not Allopatric speciation is a result of behavioral isolation, while sympatric speciation is a result of habitat isolation Allopatric speciation occurs in one place, while sympatric speciation requires a geographic barrierarrow_forwardWhat is the nature of the reproductive barrier between a species that mates at dawn (sunrise) and a species that mates at dusk (sunset)? gametic temporal habitat behavioral mechanical A mountain range divides a freshwater snail species into two isolated populations. Erosion eventually lowers the range and brings the two populations together again, but when they mate, the resulting hybrids all produce sterile young. This scenario is an example of allopatric speciation gradualism punctuated equilibrium extinction sympatric speciationarrow_forward
- Which of the following statements is false? a. Gradual speciation is most likely to occur in a large population that lives in a stable climate. b. Punctuated equilibrium is unlikely to occur in a large population that lives in a stable climate. c. Gradual speciation and punctuated equilibrium both result in the divergence of species. d. Gradual speciation is most likely to occur in a small population that experiences a rapid change in its environment.arrow_forwardWhich of the following could result in allopatric speciation? A. Two populations of a species are separated by a river that they are unable to cross. B. Two populations of a species are separated by a field that is too dry during the summertime. C. One group within a population mates during the evenings and another during the mornings. D. One group within a population develops a new mating ritual that is not recognized by the other.arrow_forwardGiven your knowledge of how species evolve, why is it not likely that speciation will occur in the majority of species on the planet as a result of climate change?arrow_forward
