Textbook Question
Chapter 24, Problem 11TYK
Morphological and genetic comparisons group 30 species of snapping shrimp (genus Alpheus) into 15 pairs of closely related species. What is the best explanation for the fact that one member of each pair lives on the Atlantic side of the Isthmus of Panama, whereas the other member of each pair lives on the Pacific side?
- a. Different predator pressures in the Atlantic and Pacific selected for differences that resulted in the reproductive isolation of these species.
- b. The pairs of species arose by allopatric
speciation when the Isthmus of Panama separated their ancestral species. - c. The 30 species of snapping shrimp evolved by sympatric speciation before the Isthmus of Panama formed.
- d. These 15 pairs of species illustrate the pattern of punctuated equilibrium, in which most speciation events take place in a short period of time.

Which of the following would be a good example of premating reproductive isolation?
A. Cross-fertilizations between the gray treefrogs, Hyla versicolor and H. chrysoscelis result in a high degree of mortality prior to hatching of hybrid eggs.
B. The mule, a hybrid between horses and donkeys is viable, but sterile.
C. Males of H. versicolor produce an advertisement call with a much slower pulse rate than males of H. chrysoscelis and females use pulse rate differences to avoid mating with the wrong species.
D. Hybrid offspring are produced from matings between leopard frogs and green frogs, but usually die before the tadpoles metamorphose into froglets.
Look at picture attached
A) What does the phylogeny suggest about the evolutionary process that led to the trait differences by habitat?
a. convergent evolution
b. adaptive radiation
c. phenotypic plasticity
B) Choose different functional forms from two of the habitats shown in the collage and describe how one or more differences in form may represent an adaptation to their different environment. Example: compare plant form for lobeliads in montane bog to cloud forest understory
Consider two species that diverged while geographically separated but resumed contact before reproductive isolation was complete. Predict the outcome over time if the two species mated indiscriminately and (a) hybrid offspring survived and reproduced more poorly than offspring from intraspecific matings or (b) hybrid offspring survived and reproduced as well as offspring from intraspecific matings.

- which statement is false? 1)In the context of the evolution of senescence, the aphorism "live fast and die young" means that organisms with a more risky behavior will have a shorter life span. 2)Allopatric speciation is a type of speciation process that takes place in different geographic locations.arrow_forwardPart A: To which other species of storm-petrel is H. matsudairae, the cold-season breeder on Japan, least closely related? A. H. monteiroi B. H. monorhis C. H. tristrami Part B: What does the phylogeny suggest about a primary reproductive barrier that exists between H. matsudairae and H. monorhis to allow speciation to occur? A. Mechanical B. Gametic barrier C. Temporal D. Nesting on different islandsarrow_forward13) Lake Malawi in Africa is home to about 200 species of allopatrically speciated cichlid fish. However, recent development around the lake is reducing the visabiliy in the lake, and as a result recently diverged species are merging back together. Why? A) Because the geneflow between species has been reduced due to the reduction in visability B) Because those species have not evolved a second reproductive isolation mechanism in addition to sexual selection C) Because the open water habitat is no longer as habitable, so the open water species are now using the bottom habitat D) Because the bottom habitat is no longer habitable, so the bottom habitat species are not using the open water habitat, leading to more hybridizationarrow_forward
- Choose True for yes and False for no, for each of the statements 1) The distribution of the two species-C populations cannot be explained by two totally independent dispersal events by the common ancestor species of A and B. True or false 2) B must share a more recent common ancestor with C1 than it does with C2. True or falsearrow_forwardTwo morphological variants in a population of medium ground finch on the Galapagos Islands have been found to exist. Individuals of each variant respond more strongly to songs produced by the same variant, and prefer to mate with individuals of their own morphological variant. What type of speciation could be in progress, and what measurements could inform the extent of prezygotic reproductive barriers that have developed? A. Sympatric speciation by sexual selection; survival and reproductive success of hybrids of the two morphological variants. B. Allopatric speciation by habitat differentiation; survival and reproductive success of hybrids of the two morphological variants. C. Sympatric speciation by sexual selection; frequencies of mating and numbers of viable offspring of the two morphological variants. D. Allopatric speciation by habitat differentiation; frequencies of mating and numbers of viable offspring of the two morphological variants.arrow_forwardWhich 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 reversalarrow_forward
- Explain the type of speciation (allopatric, parapatric, or sympatric) most likely to occur under each of the following conditions: A. A pregnant female rat is transported by an ocean liner to a new continent. B. A meadow containing several species of grasses is exposed to a pesticide that promotes nondisjunction. C. In a very large lake containing several species of fish, the water level gradually falls over the course of several years. Eventually, the large lake becomes subdivided into smaller lakes, some of which are connected by narrow streams.arrow_forwardA population of lizards colonizes a region and feeds on small arthropod species. Over time, a small group within the population starts eating different types of worms. Over time, this group develops inherited traits that help them catch, eat, and digest the worms. The two lizard groups share the same habitat but no longer recognize each other’s mating calls. What does this scenario best describe? A. speciation without geographic isolation B. natural selection without speciation C. increased genetic variation without speciation D. decreased genetic variation with geographic isolationarrow_forwardTry to outline a scenario explaining the evolution of the three species shown in panel g. Use migration, mutation, genetic drift, selection, reproductive isolation, gene flow, extinction, and many generations in your scenario. Based on your scenario, what are the components that are necessary in a population in order for it to split or diverge into two new daughter species from a single ancestor (the parent species)?arrow_forward
- Choose correct option do explain. 1.Two closely-related finch species occasionally form hybrids. These hybrids tend to have beaks of an intermediate size to their parental species, which have large and small beaks respectively. What evidence would suggest there is extrinsic postmating isolation? Group of answer choices- a.The hybrids are not able to obtain enough food due to beak size b.The hybrids die early due to deleterious gene combinations c.The hybrids cannot reproduce with members of either parent species d.The hybrids cannot reproduce with other hybridsarrow_forwarda. What are the various types of reproductive isolating mechanisms that can lead to speciation? b. What are the different modes of speciation? c. Explain how evolution produce the tremendous amount of diversity among organisms.arrow_forwardAnswer the following: This spectacular animal is a Lesser Bird of Paradise, Paradisea minor, from the highlands of Papua New Guinea. In the context of various evolutionary phenomena, why do you suppose: (a) This bird is confined to New Guinea and two nearby islands? Why would you not expect to find it in the mountains of Borneo? Explain in detail. (b) This spectacular tail presumably attracts predators; why hasn't natural selection acted to reduce it or camouflage it? Explain in detail.arrow_forward
