What is the term for the rapid evolution of new species to fill empty niches?

• Adaptive radiation

• Symbiosis

• Genetic drift

• Natural selection

Which of the following best describes adaptive radiation?

• The process by which a single species evolves into multiple species to fill different ecological niches.

• The gradual change of species over time due to environmental pressures.

• The extinction of a large number of species in a short period.

• The process by which unrelated species evolve similar traits.

Which of the following is an example of adaptive radiation?

• The development of antibiotic resistance in bacteria.

• The diversification of Darwin's finches on the Galápagos Islands.

• The extinction of dinosaurs at the end of the Cretaceous period.

• The symbiotic relationship between bees and flowers.

What role does adaptive radiation play in evolution?

• It leads to the extinction of species that cannot adapt.

• It increases biodiversity by creating new species.

• It reduces genetic variation within a population.

• It stabilizes ecosystems by maintaining existing species.

Which of the following is NOT a characteristic of adaptive radiation?

• Rapid speciation.

• Common ancestry of the species involved.

• Adaptation to a wide range of environments.

• Convergent evolution.

How does adaptive radiation contribute to the diversity of life on Earth?

• By allowing species to occupy new ecological niches.

• By reducing the number of species in an ecosystem.

• By causing the extinction of less adapted species.

• By maintaining the status quo of existing species.
