Evolution

What is a common ancestor?

• A species that has no descendants.

• An ancestral species from which two or more different species have evolved.

• A species that is currently living and reproducing.

• A type of fossil that shows evolutionary traits.

What is extinction?

• The process of a species adapting to its environment.

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

• The increase in population of a species over time.

• The migration of species to new habitats.

What is speciation?

• Speciation is the process by which new species arise from existing species, often due to genetic divergence.

• Speciation is the extinction of species due to environmental changes.

• Speciation is the migration of species to new habitats.

• Speciation is the adaptation of species to their environment over time.

What is the role of mutations in evolution?

• Mutations are changes in DNA that can lead to new traits, which may be beneficial, harmful, or neutral, influencing natural selection.

• Mutations are always harmful and lead to the extinction of species.

• Mutations have no effect on evolution and are simply random occurrences.

• Mutations only occur in response to environmental changes and do not influence genetic diversity.

What is adaptive radiation?

• A process where organisms become extinct due to environmental changes.

• A process by which organisms rapidly diversify into a variety of forms to adapt to different environments.

• A method of genetic engineering to create new species.

• A phenomenon where species remain unchanged over long periods.

What does the tree of life represent?

• The idea that all living organisms are related through common ancestry.

• A diagram showing the geographical distribution of species.

• A representation of the food chain in an ecosystem.

• A classification system for plants and animals.

What is Coevolution?

• Coevolution is the process where two or more species influence each other's evolution, often seen in predator-prey relationships.

• Coevolution is the adaptation of a single species to its environment over time.

• Coevolution refers to the extinction of species due to environmental changes.

• Coevolution is the phenomenon where species develop similar traits due to shared habitats.

What is Natural Selection?

• A process where organisms are randomly selected for survival

• A method of breeding plants for desirable traits

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

• A theory that explains the origin of species through divine intervention.

What is Divergent Evolution?

• A process where unrelated species become more similar over time due to similar environments.

• The process where two or more related species become more dissimilar over time, often due to different environments.

• A method of evolution where species remain unchanged over long periods.

• The evolution of species in isolation without any environmental influence.

What is Convergent Evolution?

• It is the process where organisms from different ancestors develop similar traits due to adapting to similar environments.

• It is the evolution of different species from a common ancestor.

• It refers to the process of species becoming extinct due to environmental changes.

• It is the phenomenon where unrelated species evolve similar traits in isolation.
