Bird guides once listed the Myrtle warbler and Audubon's warbler as distinct species, but applying the biological species concept, recent books show them as eastern and western forms of a single species, the yellow-rumped warbler. Experts must have found that the two kinds of warblers: Question 10 options: live in the same area. successfully interbreed in nature. look enough alike to be considered one species. are reproductively isolated from each other. are allopatric.

A poodle (Canis lupus familiaris) and a gray wolves (Canis lupus) can interbreed to produce viable and fertile offspring. These dogs are very similar genetically , although their are quite different in appearance. Which species concept is most likely to place poodles and wolves together into a single species? Question 19 options: biological alone morphological alone morphological and phylogenetic phylogenetic alone biological and phylogenetic
Which of the following species would have the greatest chance of going extinct? a species with a slow reproduction rate and very little genetic variation living in a changing environment a species with a fast reproduction rate and lots of genetic variation living in a changing environment a species with a slow reproduction rate and very little genetic variation living in a stable environment a species with a fast reproduction rate and lots of genetic variation living in a stable environment
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
You have 3 populations inhabiting the same landmass. Individuals from the first and second populations cannot mate with each other. Individuals from the first and third population cannot mate with each other either. Individuals from second and third populations can mate with each other but produce sterile offspring . How many species do the three populations together represent based on biological species concept?
Figure 18.23 Which of the following statements is false? Punctuated equilibrium is most likely to occur in a small population that experiences a rapid change in its environment. Punctuated equilibrium is most likely to occur in a large population that lives in a stable climate. Gradual speciation is most likely to occur in species that live in a stable climate. Gradual speciation and punctuated equilibrium both result in the evolution of new species.
What role does geographic isolation play in the formation of a new species? Group of answer choices A.If two populations become isolated geographically, then the two populations cannot interbreed with one another. There will be gene flow between the two. This will allow the two isolated populations to evolve independently leading to new species. B. If two populations become isolated geographically, then the two populations can interbreed with one another. There will be no gene flow between the two. This will allow the two isolated populations to evolve independently leading to new species. C. None of the answers are correct D. If two populations become isolated geographically, then the two populations cannot interbreed with one another. There will be no gene flow between the two. This will allow the two isolated populations to evolve independently leading to new species.
In sympatric speciation (fill in the blank) can result in (fill in the blank) and lead to formation of new species from a population that (fill in the blank) fill in the blank with the following: is geographically isolated, gene flow, reproduction isolation, is in the same environment, genetic drift, or ecological isolation
Imagine a field of monkey flowers. Some of them are pink and others are red. It turns out that the pink flowers are pollinated mostly by bumblebees, whereas the red flowers are pollinated mostly by hummingbirds. As a result pink flowers are fertilized mostly by pollen from other pink flowers, and red flowers are fertilized mostly by pollen from other red flowers. The pink and red flowers have become separate species. What type of speciation is this? Sympatric speciation type (my answer) What mechanism of reproductive isolation was involved? ??
Consider the graphic that is presented and depicts the end-point for the following scenario. At some point in the past, species A resided as a large population entirely within a rectangular geographical area. The population became divided into two isolated populations when, during a major earthquake, a mountain range arose and disrupted gene flow. Over time, the two new populations evolved independently from one another, yielding species B and C. The population comprising species C became divided into two isolated populations when another earthquake created an escarpment that disrupted gene flow. Over time, these two new populations evolved independently from one another, yielding species D and E.Imagine that you were to arrive to the region long after species D and E had evolved, completely oblivious to the scenario that is described above; survey the region for living species in this group; and conduct a cladistic analysis on those species. Assuming that the data that you were to…
Which of the following statements is false? a. Gradual speciation is most likely to occur in a large population that lives in a stable climate. b. Punctuated equilibrium is unlikely to occur in a large population that lives in a stable climate. c. Gradual speciation and punctuated equilibrium both result in the divergence of species. d. Gradual speciation is most likely to occur in a small population that experiences a rapid change in its environment.
There is a fish species that lives in a lake. As the fish population grows, competition for food increases and a group of fish locates a new food source at a different depth in the lake. Over time, two populations with distinct morphologies that allow them to eat various food sources begins to occur in the lake. Which type of speciation (allopatric or sympatric) will mostly likely occur? Why?
Use each of the following species concepts to write a claim about whether the dark and light fur mice are, in fact, different species. Your claim should demonstrate your understanding of that particular species concept. Mice with light coat colors are found in populations scattered across the southeastern US. Researchers believe the light coat color emerged in a single population. How would a biologist explain the evolution of the light coat color in populations across the southeastern US? Briefly explain your reasoning.
