Textbook Question
Chapter 14, Problem 5TYK
Bird guides once listed the myrtle warbler and Audubon’s warbler as distinct species that lived side by side in parts of their ranges. However, recent books show them as eastern and western forms of a single species, the yellow-rumped warbler. Most likely, it has been found that these two kinds of warblers
a. live in similar habitats and eat similar foods.
b. interbreed often in nature, and the offspring are viable and fertile.
c. are almost identical in appearance.
d. have many genes in common.

Students have asked these similar questions
Which 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.
These two meadowlarks are two separate species, the eastern meadowlark (Sturnella magna) and the western meadowlark (Sturnella neglecta). Although
they look very similar and have similar habitats, they are considered different species because
Group of answer choices
A. the two do not normally interbreed.
B. they have different songs.
C. they do not share the same habitat.

a. genetic divergence between populations may be overcome by gene flow.
b. speciation will occur 100% of the time.
c. gene flow between populations will be impossible.

Today, lemurs are found only on the island of Madagascar and extreme South Africa.arrow_forwardA small number of birds arrive on an island from a neighboring larger island. This small population begins to adapt to the new food plants available on the island, and their beaks begin to change. About twice a year, one or two more birds from the neighboring island arrive. What effect do these new arrivals have? A. Their arrival tends to retard adaptation to the new food plants. B. Their arrival speeds the process of speciation. C. Their arrival tends to promote adaptation to the new food plants. D. Their arrival will likely prompt genetic drift. E. Their arrival represents a colonizing event.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.

A. speciation without geographic isolation B. natural selection without speciation C. increased genetic variation without speciation D. decreased genetic variation with geographic isolationarrow_forwardHybridization between incompletely isolated populations a. always leads to reinforcement due to the inferiority of hybrids. b. can serve as a mechanism for preserving gene flow between populations, thus preventing speciation. c. only occurs in plants. d. never affects rates of speciation.arrow_forwardIn Darwin’s finches, a. occurrence of wet and dry years preserves genetic variation for beak size. b. increasing beak size over time proves that beak size is inherited. c. large beak size is always favored. d.
