Identification of different paleospecies in the fossil record: Group of answer choices: all of the options are true is easily established using reproductive isolation as a criterion for distinguishing one species from another. is facilitated by the understanding that most fossil species are ancestral to living (extant) species. is profoundly affected by assumptions of the amount of variation within species.
All of the following data types can be used as evidence of shared ancestry except similarities in _______ . a. amino acid sequence d. embryonic development b. DNA sequence e. form due to convergence c. fossil morphology f. all are appropriate
Adaptive radiations can be a direct consequence of three of thefollowing four factors. Select the exception.(A) vacant ecological niches(B) genetic drift(C) colonization of an isolated region that contains suitablehabitat and few competitor species(D) evolutionary innovation
Consider two species that diverged whilegeographically separated but resumed contactbefore reproduction isolation was complete. Predictwhat would happen over time if two species matedindiscriminately and a. hybrid offspring survived and reproducedmore poorly than offspring from intraspecificmating or b. hybrid offspring survived and reproduced aswell as offspring from intraspecific mating.Provide an example for each to illustrate yourpoint.
Which term can most accurately be used to describe evolutionary change that leads to speciation? A. microevolution b. macroevolution c. sexual selection d. natural selection e. reproductive isolation
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
In the western United States, populations of an annual plant can be found almost continuously from San Diego to Seattle. Even though individuals from the San Diego and Seattle populations never come into contact, they can still be considered part of the same species under the ________ species concept because they can potentially interbreed. A.biologicalB.morphologicalC.lineageD.habitat
Artificial classification generally shows evolutionary relationships? True or False An artificial system may use habitats as criteria for classification. True or False
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
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.
The Hawaiian Islands were "born" in the middle of the Pacific Ocean from volcanic eruptions. A genetic analysis indicates that the native species of fruit flies on the island of Kauai diversified very rapidly from a single ancestor that colonized the island.
