Sometimes evolutionary biologists have trouble determining if subpopulations of a group of organisms are a single speci or are unique species. African giraffes provide a good example of this. At least six distinct subpopulations of giraf exist, which include Rothschild's, reticulated, West African, Angolan, South African, and Masai. Each has a different pattern of spots on its fur and exists in a different geographi region in Africa. Three of the subpopulations have some overlap in Kenya and Tanzania. What criteria support the hypothesis that giraffes from different subpopulations are unique species? Giraffes from different subpopulations are unable to breed with cach other. Giraffes from different subpopulations face the same selection pressures. Giraffes from different subpopulations are not able to produce viable young. Giraffes from different subpopulations migrate betweem their home regions. Giraffes from different subpopulations experience similar patterns of genetic drift.

The elaborate tail of the peacock (Pavo cristatus) is approximately 120 cm to 150 cm long, while the tail ofthe peahen is quite short. The long tail reduces the male bird’s ability to maneuver and fly and makes him moreconspicuous to predators. Suggest at least one reason why this cumbersome structure has not been eliminatedby natural selection.
Suppose that females of one population of strawberry poisondart frogs (Dendrobates pumilio) prefer to mate with males thatare orange-red in color. In a different population, females prefermales with yellow skin. Explain how such differences could ariseand how they could affect the evolution of reproductive isolation in allopatric versus sympatric populations.
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.
The Galapagos Islands are inhabited by organisms that are similar to the organisms on the mainland of South America but they have specific characteristics that set them apart. One of the most famous groups of organisms that has been studied has been the finches. There are at least 13 different species of ground finches found throughout the Galapagos, most likely all coming from a common ancestor that arrived from the mainland of South America in the distant past. Which of the following explanation accurately explains the variation of finches on the Galapagos Islands? Question options: Divergent evolution has occurred because the finches all share characteristics that are similar to the common ancestor but differ because each species occupies different niches that require different characteristics to survive. Convergent evolution has occurred because the finches do not share characteristics that are similar to the common ancestor and differ because each species occupies…
House sparrows (Maya) were introduced to North America in 1852. Since that time thesparrows have evolved different characteristics in different locations. Sparrow populations inthe north are larger-bodied than sparrow populations in the south. This divergence inpopulations is probably at least partly a result of natural selection: larger-bodied birds canoften survive lower temperatures than smaller-bodied birds can. Colder weather in the northmay select for larger-bodied birds. What type of evolution based on natural selectionaccounts for this observation? Explain your answer.
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.
Recent reconstructions of evolutionary history are often dependenton assigning divergence in terms of changes in amino acid ornucleotide sequences. For example, a comparison of cytochromec shows 10 amino acid differences between humans and dogs,24 differences between humans and moths, and 38 differencesbetween humans and yeast. Such data provide no information asto the absolute times of divergence for humans, dogs, moths, andyeast. How might one calibrate the molecular clock to an absolutetime clock? What problems might one encounter in such acalibration?
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.

Natural selection tends to work toward genetic unity;the genotypes that are most fit produce the mostoffspring and increase the frequency of adaptive allelesin the population. Yet there remains a great deal ofvariability within the populations of species. Describethe factors that contribute to this genetic variability. Provide the link of references
DNA-sequencing studies for a gene in two closely relatedspecies produce the following numbers of sites that vary:Synonymous polymorphisms 50Nonsynonymous polymorphisms 20Synonymous species differences 18Nonsynonymous species differences 2Does this result support neutral evolution of the gene?Does it support an adaptive replacement of aminoacids? What explanation would you offer for theobservations?
Which part of these statements isn't right ? A species is a group of organisms that can potentially interbreed with one another to produce viable, fertile offspring. Speciation is when two new species form from one original one. Sympatric speciation occurs when there is a geographic separation of a population. Allopatric speciation occurs while the population remains in the same area. Adaptive radiation occurs when one species evolves into many to fill several different niches. Natural selection requires traits to be passed from parent to offspring, more offspring are produced than can survive creating competition, and inherited traits vary among offspring. Fossils, Anatomy and embryology, biogeography, and molecular biology all provide support for the theory of evolution. Evolution can be driven by many different things. Mutations are changes in DNA that create new alleles in a population. Gene flow is the flow of alleles in and out of a population resulting from the migration…
Lithobates clamitus. also know as the green frog and bronze frog can range in in skin color from pure to brown to pure green and a mixture of both. As their habitats change frogs with a mixture of both colors have a higher fitness as they are better able to hide from predators. 1. If the change in the distribution of this trait is the result of natural selection, name the mode of selection (ie: Balancing, Disruptive, etc...) 2. If a small group of male frogs end up joining this population from a different population of frogs, which process of selection describes the movement of alleles present in the male frog? 3. The process you named in “c” ________ the genetic variation in the population that the male frog joined? (increase, decrease, or stay the same?)
