Which of the following speciation mechanisms is most likely to be responsible for the divergence of a single species into two distinct species due to geographic isolation caused by a mountain range? Sympatric speciation Allopatric speciation (dispersal) Allopatric speciation (vicariance) Parapatric speciation
Which of the following statements about sympatric speciation is correct? It is a process through which two populations can diverge and develop reproductive isolation while in two different geographic area. It is the most common mechanism for populations to form independent species. Postzygotic isolation is the main form of reproductive isolation for the sympatric speciation process. Genetic isolation through large scale chromosomal mutations, such as chromosome inversion or polyploidy, are more likely contributing to sympatric speciation. None of the above
A small group of individuals from a bird species is carried by strong winds to a distant island, where they establish a new population that eventually diverges into a separate species. This is an example of: Parapatric speciation Allopatric speciation (vicariance) Allopatric speciation (dispersal) Sympatric speciation
Agrostis tenuis grasses tolerant of zinc metals in the soil (after evolving from metal-sensitive grasses near mine soils contaminated with zinc over the past 100 years), is an example of: allopatric speciation by vicariance allopatric speciation by dispersal peripatric speciation parapatric speciationE. sympatric speciation
Each of the examples describes either a speciation event or potential speciation event. Place each scenario under allopatric, parapatric, or sympatric speciation. Allopatric speciation Parapatric speciation Sympatric speciation
The phyletic gradualism model of speciation asserts that; Most speciation occurs allopatrically Speciation is a slow and gradual process that occurs as species slowly become geographically separated speciation occurs in quickly and then is followed by periods with little if any change Most speciation occurs sympatrially
Speciation events can occur on a variety of timescales. Which factor is NOT likely to influence the rate of speciation? Selection pressures Color of the organism Generation time Mutation rate
What are characteristics of sympatric speciation? Select all that apply. Reproductive isolation necessary to end gene flow Divergence within a population leads to speciation Absence of a physical barrier Presence of a physical barrier Reproductive isolation unnecessary to end gene flow
Of the following species concept, which one emphasizes reproductive isolation as the major cause for speciation? Phylogenetic species concept Morphological species concept Biological species concept Evolutionary species concept
Which of the following is NOT necessary for speciation to take place? Genetic divergence Physical separation by a geographic barrier Separation in space or time Reproductive isolation
The biological species concept primarily focuses on which of the following criteria for defining a species? Interbreeding and reproductive isolation Phylogenetic relationships Ecological roles Morphological similarities
How is sympatric speciation different from allopatric speciation? Group of answer choices Allopatric speciation requires a geographic barrier, while sympatric speciation occurs in one place Allopatric speciation results in hybrids, while sympatric speciation does not Allopatric speciation is a result of behavioral isolation, while sympatric speciation is a result of habitat isolation Allopatric speciation occurs in one place, while sympatric speciation requires a geographic barrier
