Theory of Evolution Questions based on Test Wizard Science 2018-2019
Give an example of a physiological adaption.
Sweating
Fish, reptiles, and mammals each contain gill slits during part of their embryological development. Which statement best explains this observation?
They all had a common ancestor
For many mammals, if they have the same structure, number, position and shape of the bones most likely indicates that they may have...
a common ancestor
A population of white moths lives in a forest near a factory. This factory burns coal and pollutes the air with black dust. Over time, this dust has settled on the trees in the area, making them darker in color. This could result in...
a decrease in the white moth population
When a species includes organisms with a wide variety of traits, it is most likely that this species will have...
a greater chance to survive
Charles Darwin proposed that organisms produce many more offspring than can possibly survive on the limited amount of resources available to them. According to Darwin, the offspring most likely to survive are those that...
are best adapted to the environment
Mother rattlesnakes care for and protect their young. Baby rattlesnakes find safety in the coils of their mothers. Female snakes stay together for the first few weeks after giving birth. This gathering of female rattlesnakes provides a safe environment for newborn rattlers. This is an example of which type of adaptation?
behavioral
Give an example of a homologous pair.
bones in the front leg of a dog and bones in the wing of a bat
According to the theory of biological evolution, most present-day species of organisms...
descended from earlier, different species of organisms
A certain plant species, found only in one particular stream valley in the world, has a very shallow root system. An earthquake causes the stream to change its course so that the valley in which the plant species lives becomes very dry. As a result, the species dies out completely. The effect of this change on this plant species is known as...
evolution
Biologically similar organisms have similar DNA and proteins. This statement supports the concept of...
evolution
Two squirrel populations are prevented from mating only because they live on opposite sides of the Colorado River. This situation is an example of...
geographic isolation
Species of bacteria can evolve more quickly than species of mammals because bacteria have...
higher rates of reproduction
Organisms best adapted to a changed environment are more likely to reproduce and pass their genes to offspring is an example of...
modern theory of evolution
The modern theory of evolution states that a basis for variation within a species is provided by...
mutations
Variations within a species are most likely the result of...
mutations and sexual reproduction
Give an example of a structural adaption.
quills on a porcupine
Fossils would most likely be found in...
sedimentary rocks that are 500 million years old
A body part, such a turtle's shell that protects its soft body, is a ____________________ adaptation
structural
Organisms with favorable variations reproduce more successfully than organisms with less favorable variations. This statement best describes the concept of...
survival of the fittest
A group of organisms became reproductively isolated from its original population due to geographic separation. This group would most likely be...
unable to successfully interbreed with its original population
A large population of houseflies was sprayed with an insecticide. The appearance of some houseflies that are resistant to this insecticide supports the concept that...
variation exists within a species
Give an example of an analogous pair.
wing of an insect and wing of a bird
What is a vestigial structure
A structure that has no function but that once functioned in an ancestor
Give an example of a vestigial structure.
Appendix
Give an example of a behavioral adaption.
Fish swim in schools
