What is natural selection?
The process by which individuals that are better suited to their environment survive and reproduce most successfully.
The random process by which individuals gain new traits.
The process by which all organisms automatically adapt to their environment.
The method by which individuals choose their mates based on specific traits.
What is genetic variation?
The lack of differences among individuals in a population.
The uniformity of genes in different species.
The differences in DNA among individuals within a population or species.
The process of inheriting physical traits from parents.
What are homologous structures?
Structures in different species that are similar because of common ancestry.
Structures that serve the same function in different species but are not similar in origin.
Useless structures that serve no purpose in the current organism.
Structures that are different in every species.
What is an adaptation?
A temporary change in behavior in response to an environmental challenge.
A physical or behavioral trait that has evolved over time to allow an organism to better survive in its environment.
A sudden change in the DNA of an organism.
The process by which an individual moves to a different environment.
What is a mutation?
A change in a DNA sequence that affects genetic information.
A deliberate change in an organism's genetic material.
A process by which organisms adapt to their environment.
A disease that affects genes.
What is the classification system in biology used for?
To organize living organisms into groups based on their similarities and evolutionary history.
To classify all living organisms as either plants or animals.
To determine which animals are the strongest.
To organize organisms by their color.
What was Pangaea?
A theory that suggests all current continents were once part of a single supercontinent.
The first species of dinosaur.
A type of ancient fossil.
The ocean that surrounded the early Earth.
What are analogous structures?
Structures that are similar in different species because of common ancestry.
Structures in different species that have the same function but are not derived from a common ancestor.
Structures that are present in an organism but have no current function.
Identical structures found in closely related species.
What role do mutations play in evolution?
They decrease genetic variation.
They have no role in evolution.
They are the only source of new genetic material for natural selection to act upon.
They always result in negative effects on the organism.
What evidence supports the theory of Pangaea?
The identical design of all continents.
The distribution of fossils and the similarity of rock formations across continents.
The presence of the same species of animals on every continent.
Modern GPS measurements.
What is the significance of vestigial structures in evolution?
They prove that evolution does not occur.
They are structures that have lost most or all of their ancestral function in a given species, indicating past evolutionary adaptations.
They are the most important structures for an organism's survival.
They are newly evolved structures that are crucial for survival.
How does adaptation affect a species' survival?
It has no effect on survival.
It decreases a species' chance of survival.
It increases a species' chance of survival by making it better suited to its environment.
It ensures that a species will not change over time.
What is the concept of survival of the fittest?
It is the process by which the strongest individuals survive and reproduce.
It is the process by which the most intelligent individuals survive and reproduce.
It is the process by which individuals that are best adapted to their environment survive and reproduce.
It is the process by which all individuals survive and reproduce equally.
What is the concept of convergent evolution?
It is the process by which different species evolve similar traits.
It is the process by which similar species evolve different traits.
It is the process by which species evolve at the same rate.
It is the process by which species evolve in the same environment.
What is the significance of the fossil record in understanding evolution?
It provides evidence of the existence of ancient organisms.
It provides evidence of the existence of ancient organisms and shows how species have changed over time.
It provides evidence that all species have remained unchanged over time.
It provides evidence that evolution does not occur.
