Evidence of Evolution

What are vestigial structures?

• Body parts that have lost their original function through evolution.

• Body parts that are fully functional and necessary for survival.

• Body parts that are used for reproduction.

• Body parts that have evolved to serve a new function.

What is natural selection?

• The process by which organisms better adapted to their environment tend to survive and produce more offspring.

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

• The theory that all species evolve from a common ancestor.

• A technique used in genetic engineering to modify organisms.

What is the significance of DNA in evolution?

• DNA is responsible for the physical appearance of organisms.

• DNA provides the genetic information that can change over generations, leading to evolution.

• DNA is only important for reproduction and not for evolution.

• DNA has no role in the process of natural selection.

What is speciation?

• The process of natural selection leading to extinction.

• The formation of new and distinct species in the course of evolution.

• The adaptation of species to their environment over time.

• The migration of species to new habitats.

What does Darwin's theory of evolution suggest?

• Species remain unchanged over time.

• Species change over time.

• Species are created by divine intervention.

• Species are always the same as their ancestors.

What are homologous structures?

• Body parts in different species that are similar due to common ancestry.

• Body parts in different species that serve the same function but have different origins.

• Body parts in the same species that are identical in structure and function.

• Body parts that have evolved independently in different species.

What is the role of environmental changes in evolution?

• Environmental changes can lead to adaptations in species, influencing their evolution.

• Environmental changes have no impact on species adaptation.

• Environmental changes only affect the climate, not species.

• Environmental changes are irrelevant to the process of evolution.

What characteristic did Darwin observe about the finches on the Galapagos Islands?

• Their feathers.

• Their beaks.

• Their size.

• Their colors.

What is extinction?

• The process of an organism adapting to its environment.

• The end of an organism or a group of organisms, often due to evolutionary changes or environmental factors.

• The increase in population of a species over time.

• The migration of organisms to a different habitat.

What is adaptation?

• A process of changing the environment to suit an organism's needs.

• A trait that helps an organism survive and reproduce in its environment.

• A method of communication between different species.

• A type of food that organisms consume for energy.
