Two species of fish had recently undergone sympatric speciation. The males of each species had a different coloring through which females could identify and choose a partner from their own species. After some time, pollution made the lake so cloudy it was hard for females to distinguish colors. What reproductive barrier might occur? Explain your answer.

Speciation can occur when two populations of a species become separated from each other. What is the best explanation for why speciation occurs?
Two species of fish had recently undergone sympatric speciation. The males of each species had a different coloring through which the females could identify and choose a partner from their own species. After some time, pollution made the lake so cloudy that it was hard for females to distinguish colors. What might take place in this situation?
The pupfishes in the Death Valley region are an example of which evolutionary process? (a) background extinction (b) allopatric speciation (c) sympatric speciation (d) allopolyploidy (e) paedomorphosis
If two groups of mice live on opposite sides of a river, they are two separate species. What two processes must have occurred in order for them to have become separate species?
Climate warming could lead to all-female populations of bearded dragons, resulting in extinction of the species. What are some other potential effects of climate warming on natural populations of organisms?
What is Allopatric speciation? A) When a population is separated from the main group by a barrier and becomes a new species B) When a population mutates into a new species C) When a population develops into a new species without any physical barriers to isolate them
Which of the following would NOT be a reason for a speciation event? Group of answer choices comfortable environmental conditions plentiful food supplies very few natural disasters and/or catastrophic events increased amounts of predators lack of predators
A population of chipmunks lives across the length of a valley in the mountains. One day a large section of the mountain breaks off, and the resulting rockslide divides the valley in half. Over time, the chipmunks on either side of the rockslide evolve and become different species. What type of speciation is this?
Which could lead to allopatric speciation by two populations of snail? Group of answer choices A. creation of a new mountain range between two populations B. a mutation in all members of one population which prevents gamete fusion between the two populations C. a change in breeding time of one population D. a change in mating behavior in one population but not in the other
Given your knowledge of how species evolve, why is it not likely that speciation will occur in the majority of species on the planet as a result of climate change?
When the isthmus of Panama (land bridge that connects north and south America) arose about 3 million years ago, it caused species of fish to diverge into sister species located in either the caribean or pacific ocean. Why did they form separate species? A) Because this is an example of sympatric speciation B) Because the tides are different on each side of the land bridge C) Because different predators in each ocean caused the populations to diverge D) Because the populations were reproductively isolated
Which of the following is an example of sympatric speciation? Group of answer choices a. birds moving to the far side of a mountain range b. squirrel populations on opposite sides of the Grand Canyon c. insects moving to new host plant species d. fish in two different lakes
