Can factors that cause sympatric speciation also cause allopatricspeciation? Explain.
Explain the type of speciation (allopatric, parapatric, or sympatric) most likely to occur under each of the following conditions:
A. A pregnant female rat is transported by an ocean liner to a new continent.
B. A meadow containing several species of grasses is exposed to a pesticide that promotes nondisjunction.
C. In a very large lake containing several species of fish, the water level gradually falls over the course of several years. Eventually, the large lake becomes subdivided into smaller lakes, some of which are connected by narrow streams.
Over time, enough genetic variations can develop within a population to cause it to undergo speciation. Identify the various mechanisms that will prevent different species from being able to reproduce successfully. Which of these mechanisms is the most influential in keeping species sperate?

- How come dispersal is still allopatric speciation? I was under the impression that a new geographical barrier would have to develop and separate a once-uniform species. Also, what's the difference between vicariance and allopatric speciation?arrow_forwardWhat are the most common mechanisms of sympatric speciation and in which major group of organisms does this happen most often? Distinguish between sympatric, allopatric and parapatric speciation. What is considered the (far) more common mechanism of species formation? What does "gene flow" between populations mean?arrow_forwardWhich 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 abovearrow_forward

Does this species concept apply in all situations? Think of an example from nature where the biological species concept would NOT be that applicable. Which species concept would be better in this example? How does speciation occur? What environmental factors might contribute to speciation? Can an individual speciate? Use terminology for the two kinds of speciation we have learned about. What is “gene flow”? What does it mean if there is NO gene flow? Two groups of individuals are separated by either side of a canyon. One researcher found that they do not cross the canyon at any point. The group on the north side have fluffy tails and thicker coats, and they do not eat moss. The south side individuals eat moss almost exclusively, have a thin coat and tail, but otherwise are generally identical. When in the lab they mated successfully, and the offspring of that mating also mated…arrow_forward
