Patterns of Evolution

What is convergent evolution?

• The process where unrelated organisms develop similar traits due to similar environmental pressures.

• The evolution of similar traits in related organisms due to different environmental pressures.

• The process by which organisms evolve to become more different from their ancestors.

• The adaptation of organisms to their environment over time, leading to increased diversity.

What is divergent evolution?

• A process where unrelated species evolve similar traits due to similar environments.

• A type of evolution where related species evolve different traits or adaptations due to different environments.

• An evolutionary process that leads to the extinction of species.

• A mechanism by which species remain unchanged over time.

What is coevolution?

• A process where species evolve independently of each other.

• The process where two or more species influence each other's evolution.

• A method of artificial selection in agriculture.

• The phenomenon of species becoming extinct due to environmental changes.

What is punctuated equilibrium?

• A gradual and continuous process of evolution.

• A pattern of evolution characterized by long periods of stability interrupted by short bursts of significant change.

• An evolutionary theory that suggests all species evolve at the same rate.

• A method of classifying species based on their physical characteristics.

What is speciation?

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

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

• The extinction of a species due to environmental changes.

• The migration of species to new habitats for survival.

What is gradualism?

• A theory that evolution occurs rapidly and in bursts

• A theory that evolution occurs slowly and steadily over long periods of time

• A theory that all species are created simultaneously

• A theory that evolution is a random process without direction

What is an example of convergent evolution?

• The development of wings in birds, bats, and pterosaurs, which are unrelated but adapted to flying.

• The evolution of different species from a common ancestor, such as the diversification of mammals.

• The adaptation of polar bears to cold environments through thick fur and fat layers.

• The process by which species evolve in isolation from one another, leading to unique traits.

What is an example of divergent evolution?

• The different beak types of Darwin's finches, which evolved from a common ancestor based on available food sources.

• The similar body structures of dolphins and sharks, which evolved in similar environments.

• The development of antibiotic resistance in bacteria due to overuse of antibiotics.

• The variation in color patterns of butterflies in different habitats.

What is adaptive radiation?

• The gradual evolution of species in a stable environment.

• The rapid evolution of diversely adapted species from a common ancestor in response to new environments.

• The extinction of species due to environmental changes.

• The process of species becoming more similar over time.
