Two species of fish had recently undergone sympatric speciation. The males of each species had a different coloring through which females could identify and choose a partner from her own species. After some time, pollution made the lake so cloudy it was hard for females to distinguish colors. What might take place in this situation?
The difference between sympatric and parapatric speciation is ___ .a. parapatric speciation occurs only in velvet walking wormsb. sympatric speciation requires a barrier to gene flowc. the extent of overlap in ranged. reproductive isolation does not occur
A major mechanism of speciation in plants but not in animals isa. adaptation to new environments.b. polyploidy.c. hybrid breakdown.d. genetic changes that alter the organism’s niche.e. both a and d.
Natural history museums house collections of many kinds ofanimals. These collections contribute to our understanding ofevolution. Most museums still participate in limited collecting,concentrating on particular groups or organisms that will provide aparticular insight into evolution. A bird that was suspected of beinga rare hybrid recently appeared in Missouri, so it was collected forstudy at a nationally recognized museum. Some members of thelocal bird-watching community were upset. a)Do you think that collecting birds such as this suspected hybrid is scientifically justified? Why?
Males of different species of the fruit fly Drosophilathat live in the same parts of the Hawaiian Islandshave different elaborate courtship rituals. These rituals involvefighting other males and making stylized movements thatattract females. What type of reproductive isolation does thisrepresent?(A) habitat isolation(B) temporal isolation(C) behavioral isolation(D) gametic isolation
Over the years, you notice that a chipmunk that has been making narrow tunnels under trees in your backyard has acquired a narrower body shape with strong digging arms and legs. Which of the following describes how Lamarck would view this change in the chipmunk's body. Question 17 options: The chipmunk will undergo rapid speciation, followed by long periods of no speciation. The chipmunk will only pass on genetic information to it's offspring, and the environment will shape how they develop. The chipmunk will pass the acquired traits in it's body to it's offspring. If this chipmunk is better adapted to it's environment, it will be more likely to reproduce and pass on it's genes.
When two populations are reproductively isolated, what else must occur for speciation to happen? (a) gene ﬂow (b) genetic divergence (c) coevolution (d) convergent evolution (e) none of the above
In which of the situations below would speciation be most likely to occur? You can choose more than one answer. a. Seven lemurs escape from an enclosure at Duke University. To everyone's surprise, they establish a small but viable population coexisting successfully with humans in a partly suburban environment very different from their native Madagascan habitat. b. Bighorn sheep occupy mountains from Canada to Death Valley in Southern California, interbreeding all along the way. The populations at the two ends of the range live in very different environments. c. A few individuals of a butterfly species were blown to an island during a severe storm. d. A population of juniper shrubs is split by the formation of a canyon. Every year, strong winds carry a small amount of the shrubs' pollen across the canyon.
Which is a criticism of sympatric speciation? A.) many cases of sympatric speciation are actually microallopatry B.) allopatric speciation is less common and scientists should focus more attention on locating additional examples C.) sympatric speciation is only associated with changes in ploidy, a process so rare that it's relatively unimportant D.) since most examples of sympatric speciation involve post zygotic isolation, hybridization nearly always results in their reversal
Consider the speciation event via which your species O. virginianus White tail deer split from species b O. hemionus Mule Deer (the more closely related species). Taking into account the basic biology of these organisms, briefly describe how each of the four evolutionary forces might have acted in producing that speciation event: genetic drift, gene flow, natural selection and nutation) .Genetic drift .Gene Flow .Nautual selection . Mutation
Analysis of Rhagoletis fly populations in North Americaprovides evidence that if some members of an insectpopulation shift to a new host species,a. sympatric speciation may eventually result.b. adaptive radiation is likely.c. little or no subsequent genetic divergence is likely.d. sympatric speciation is probably impossible in insects.
A. What kind of speciation do we normally associate with members from one population being geographically displaced to a new, smaller population? Geospiza scandens B. What kind of speciation do we normally associate with members of a population that become ecologically, genetically or behaviorally distinct within that population such that they become reproductively isolated?
