Students have asked these similar questions
Species can vary in several ways. Which of the following is one of Darwin’s ideas that was accepted by most scientists of his time due to the large number of fossils being discovered at that time?
A. Species that live in seawater can also live on mountains.
B. Species have specific adaptations to their local environment.
C. Species vary around the world.
D. Species change over long periods of time.
Researchers have found fossils of Eocene horse species in Colorado. Deeper deposits contain smaller species, and more recent deposits contain larger species. How does this observation support the theory of evolution?
A.
It provides evidence that species change over time.
B.
It does not support the theory of evolution.
C.
It shows that all species are related to each other.
D.
It proves that environments have changed over time.
E.
It suggests that species are unchanging and of recent origin.
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.

- A small number of animals moves away from a large ancestral population on the continental mainland and colonizes an island. Which of the following is likely to occur? A. Genetic diversity will decrease on the mainland, because of a population bottleneck. B. Alleles that were more rare on the mainland are likely to become more common on the island, because of the founder effect. C. Genetic diversity will be lower on the island than the mainland, because of the founder effect. D. Mutations rates will increase on the island, in response to selection pressures in the new environment.arrow_forwardSeveral very distantly related species (e.g., bats, birds, insects) have evolved the capability of flight. The most recent common ancestor of insects and vertebrates likely lived over 500 million years ago and was flightless. This independent evolution of flight in multiple, distantly related taxa is an example of what evolutionary process/pattern? a. Evolutionary reversal b. Convergent evolution c. Speciation d. Synapomorphyarrow_forwardAccording to "The Complex Evolution of Homo sapiens”, what two major things (or pieces of evidence) confirm that our species evolved in Africa?

- One hypothesis for the Cambrian explosion was an increase in predator-prey relationships. It is thought that the resulting co-evolution of predator and prey may have been a factor in the rapid speciation of animals seen during this time. What findings in the fossil record would most support this? Group of answer choices a. increased incidence of larger-bodied animals b. increased incidence of sessile animals c. decreased incidence of animals with bilateral symmetry d. increased incidence of animals with radial symmetry e. increased incidence of shells, bony plates, spines, and/or clawsarrow_forwardSpecies that are more vulnerable to certain risk factors are more likely than others to become extinct. For example, species with a unique lineage, such as the giant panda, are likely to be at severe risk of extinction.a. Should our limited resources for species protection be focused on species that are at the highest risk of extinction?b. Do you support the idea that high-risk species may be less successful products of evolution and should not receive extraordinary protection?arrow_forwardWhich of the following is part of a clade believed to have died out, leaving no descendants? a.

- There are several other species pairs like these meadowlarks in the Great Plains (orioles, chickadees, yellow-rumped warblers, and flickers). Some are considered separate species and others aren’t, even though they are quite different in physical appearance. What might have geologically isolated these different bird populations, leading to speciation? Group of answer choices A. recent (geologically) continental glaciation B. hurricanes from the Gulf of Mexico C. the Mississippi River D. prairie fires in the springarrow_forwardA.
