Evidence of Evolution

What is the importance of fossils in understanding evolution?

• Fossils provide evidence of past life forms and how they have changed over time.

• Fossils are primarily used for dating rocks and geological formations.

• Fossils are only found in sedimentary rocks and have no relevance to evolution.

• Fossils are the remains of organisms that lived only in the last century.

What does evolution mean in biology?

• A change in the traits of a population across generations of a species.

• A process by which organisms develop new organs to adapt to their environment.

• The ability of an organism to survive in its environment without change.

• A method of reproduction that involves genetic cloning.

What is natural selection?

• A process where organisms with better adaptations to their environment tend to survive and produce more offspring.

• A method of breeding plants and animals for desired traits.

• A theory that suggests all species are static and unchanging.

• A phenomenon where all organisms have an equal chance of survival.

How does natural selection lead to evolution?

• Natural selection eliminates all individuals with less favorable traits, causing immediate evolution.

• Natural selection favors individuals with advantageous traits, leading to changes in the population over time.

• Natural selection has no impact on the genetic diversity of a population.

• Natural selection only affects the physical characteristics of organisms, not their behavior.

What role do mutations play in evolution?

• Mutations introduce new traits that can be beneficial, neutral, or harmful, contributing to genetic diversity.

• Mutations have no impact on evolution and are simply random changes in DNA.

• Mutations only lead to harmful traits that decrease an organism's chances of survival.

• Mutations are always beneficial and lead to the improvement of species.

What is the difference between a theory and a law in science?

• A theory describes what happens under certain conditions, while a law explains why something happens.

• A theory is a proven fact, while a law is a hypothesis.

• A theory explains why something happens, while a law describes what happens under certain conditions.

• A theory is less reliable than a law, which is always true.

What is an ancient ancestor?

• A species that has never existed before.

• An extinct species related to a current species.

• A living species that has evolved recently.

• A species that is currently thriving in the wild.

What is biological evolution?

• A process by which organisms adapt to their environment over generations.

• A theory that explains how species change over time.

• A method of classifying living organisms based on their characteristics.

• A phenomenon where species become extinct due to environmental changes.

What evidence supports the theory of evolution?

• Fossil records, genetic similarities, and observed changes in species over time.

• Only fossil records from ancient species.

• Genetic differences among species.

• The belief in creationism.

What is the concept of common descent?

• The idea that all living organisms share a common ancestor.

• The belief that species evolve independently without any common ancestry.

• The theory that life originated from non-living matter.

• The notion that all organisms are created separately and do not share any lineage.
