This principle states that deeper rock layers are older than the layers above them.
What is the Law of Superposition?
A mutation is a change in this molecule that carries genetic information.
What is DNA?
One of the three conditions of natural selection: individuals in a population must show this. When a species has many different outcomes of one trait (different eye colors)
What is variation?
An inherited trait that helps an organism survive and reproduce is called this.
a. natural selection
b. adaptation
c. evolution
What is an adaptation?
a. Scotland
b. Canada
c. South Korea
d. Turkey
A. Scotland
This type of fossil is used to determine the relative age of rock layers because it lived for a short time and was widespread.
What is an index fossil?
Mutations can be harmful, helpful, or this third type that does not affect survival.
What is neutral?
Another condition of natural selection: more offspring are produced than can survive.
a. disease
b. overproduction
c. overhunting
What is overproduction?
Camouflage is an example of this type of adaptation.
(behavioral or physical)
What is a physical adaptation?
Which soft drink once contained cocaine as one of its original ingredients?
Coca-Cola
This process can wear away rock layers and sometimes expose fossils at Earth’s surface.
What is erosion?
A mutation that occurs that makes the species less likely to survive.
negative mutation
This condition means individuals with helpful traits are more likely to survive and reproduce.
a. selection
b. variation
c. evolution
What is selection?
Migration is an example of this type of adaptation.
(behavioral or physical)
What is a behavioral adaptation?
A majority of adults have how many permanent teeth?
32
If a trilobite fossil is found below a dinosaur fossil in rock layers, which fossil is older?
What is the trilobite fossil?
This type of mutation might improve an organism’s chances of survival in its environment.
What is a beneficial (positive) mutation?
If darker beetles survive better on dark rocks and reproduce more, what will happen to the population over time?
What is that more beetles will be dark-colored?
Why are adaptations environment-specific?
What is because a trait that helps in one environment may not help in another?
What country uses approximately four billion miles of toilet paper each year?
a. USA
b. China
c. Greece
China
Scientists find the same index fossil in two rock layers miles apart. What can they conclude about the layers?
What is that the layers are the same relative age?
Why do mutations increase variation in a population?
What is because they create new traits or new versions of genes?
What is one example of an adaptation
camouflage, strong legs, mimicry, etc.
How are mutations and adaptations connected?
What is that mutations create new traits, and helpful ones can become adaptations through natural selection?
What is the square root of 64?
8
