Bird guides once listed the myrtle warbler and Audubon's warbler as distinct species. Recently, these birds were reclassified as eastern and western forms of a single species, the yellow-rumped warbler. Which of the following pieces of evidence, if true, would be cause for this reclassification?
- A. The two forms interbreed often in nature, and their offspring survive and reproduce well
- B. The two forms live in similar habitats and have similar food requirements.
- C. The two forms have many genes in common.
- D. The two forms are very similar in appearance.

A population of interbreeding birds has been split by a geological event after which the isolated part of the
population started to evolve into an incipient species with different mating rituals. Due to a recent environmental
change the two populations are now able to potentially mate again in what is called a hybrid zone. Mating does
take place every now and then but the hybrid offspring appear less able to survive. As a consequence, mating
rituals start to diverge even further. We call this process of continued divergence?
O Fusion
O Behavioral isolation
Reinforcement
O Postzygotic isolation
O Stability
Which of the following is an example of postzygotic reproductive isolation?a. Sperm of species A dies in the oviduct of species B before fertilization can take place.b. Hybrid zygotes between species A and B are spontaneously aborted early indevelopment.c. The mating seasons of species A and B do not overlap.d. Males of species A are not attracted to the pheromones produced by the females ofspecies B.
Two parents, who are thought to be different species, mate and produce viable hybrid offspring. When two of these hybrids mate, their offspring are not viable. What is the BEST interpretation of this data?
A.
The original parents are the same species because they can breed together.
B.
The original parents are the same species because they can breed together and produce viable offspring.
C.
The original parents are not the same species because they produce hybrids that impair the species’ development or survival in its environment.
D.
The original parents are not the same species because they produce hybrids that can have reduced viability and fertility when they mate.

- Since Western and Eastern meadowlarks are similar in appearance, one could assume that both are members of the same species. However, the Western meadowlark sings a song that is distinct from the Eastern meadowlark, preventing the two from mating. Therefore, one could also assume that Western and Eastern meadowlarks each represent their own species. Identify which concepts characterize both assumptions.arrow_forwardIn the United States, the rare red wolf (Canis lupus) has been known to hybridize with coyotes (Canis latrans), which are much more numerous. Although red wolves and coyotes differ in terms of morphology, DNA, and behavior, genetic evidence suggests that living red wolf individuals are actually hybrids. Red wolves are designated as an endangered species and hence receive legal protection under the Endangered Species Act. Some people think that their endangered status should be withdrawn because the remaining red wolves are hybrids, not members of a "pure" species. Do you agree? Why or why not?arrow_forwardScientists study the possible effects of human activity on the genetic variations within members of two populations of sparrows, A and B, that live within similar ecosystems. Population A lives in a recreational campsite while population B lives in a nature preserve. Both populations exhibit similar genetic variation between the parent population and second generation. However, a tornado touches down in the habitat of population A during the lifespan of the second generation. Which statement best describes the predicted difference between the third generation of the two populations? A - Population B underwent a speciation that will lead to an increase in the genetic variation of the third generation compared to population A due to natural selection. B - Population A underwent a speciation that will lead to an increase in the genetic variation of the third generation compared to population B due to natural selection. C - Population B underwent a bottleneck effect that will lead to a…arrow_forward
- Two 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_forwardThe domestic dog belongs to the species Canis familiaris. The great dane, golden retriever, cocker spaniel, fox terrier and chihuahua are different breeds within this species. a List some differences between these breeds. b List some differences within one of these breeds. c Considering the differences in size between the largest and smallest of these breeds, explain how it is that they are all considered to belong to the same species.arrow_forwardThe red wolf (Canis rufus) was once widespread in the southeastern United States but was declared to be extinct in the wild. Biologists bred captive red wolf individuals and reintroduced them into areas of eastern North Carolina, where they are federally protected as endangered species. The current wild population is estimated to be about 100 individuals. However, a new threat to red wolves has arisen: hybridization with coyotes (Canis latrans), which have become more numerous in the areas inhabited by red wolves. Although red wolves and coyotes differ in morphology and DNA, they are capable of interbreeding and producing fertile offspring. Social behavior is the main reproductive barrier between the species and is more easily overcome when same-species mates are rare. For this reason, some people think that the endangered status of the red wolf should be withdrawn and resources should not be spent to protect what is not a “pure” species. Do you agree? Why or why not?arrow_forward
- A 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_forwardWhich of the following is NOT true for the speciation of finches in the Galapagos islands? A. Natural selection acted on beak shape, and resulted in different beak morphologies for different food sources. B. Assortative mating reinforced existing divergence between birds. C. Speciation of finches started by birds starting to specialize on different food sources. D. Speciation of finches on the same island is due to allopatric speciation.arrow_forwardSpecies A and B have long wings, whereas species C has short wings.

- Distinct species that are able to interbreed in nature are said to “hybridize,” and their offspring are called “hybrids.” The gray oak and the Gambel oak can mate to produce fertile hybrids in regions where they co-occur. However, the gene flow in nature is sufficiently limited that, overall, the two species remain phenotypically distinct. If the hybrid offspring survive well and reproduce to the extent that there is a large population of hybrid individuals that breed between themselves but do not interbreed with either of the two original parent species (the gray and the Gambel), which of the following would you say most likely led to the new hybrid species?(a) prezygotic reproductive barriers (b) sympatric speciation (c) allopatric speciation (d) postzygotic reproductive barriers (e) none of the abovearrow_forwarda.) In either a secondary or a primary hybrid zone, what do the graphs above indicate about the relative fitness of the hybrid toads away from the 0-kilometer site on the cline? Why? b.) One explanation for the “stepped cline” in both gene frequencies and morphology is that B. bombina and B. variegata first diverged in allopatry and are now forming a secondary hybrid zone. Is the spatial pattern of genetic and morphological variation consistent with this explanation? Why or why not? c.) What would have to be true for the ecological niches of these two-color forms of toad for disruptive selection to be acting on so many loci in parapatry?arrow_forward(b) There is a positive correlation between branch width of trees and hind limb length of the brown anole lizard: Wide branch diameter = long hind limbs Narrow branch diameter= short hind limbs A group of lizards becomes separated from the main group on Island A due to a catastrophic hurricane that carries this small group out to sea. A few lizards are able to make it to uninhabited, dry land (Island B) and breed over several generations separated from the lizards on Island A.
