Evidence of Evolution Reading Comprehension

What are fossils?

• Living organisms

• Preserved remains or traces of organisms from the past

• Newly discovered species

• Genetic mutations

What is the role of transitional fossils in evolutionary history?

• They show no change

• They bridge the gap between different species

• They are unrelated to evolution

• They only show extinction events

What does the process of evolution lead to over many generations?

• Extinction of species

• Development of new traits and species

• Stability of species

• Decrease in biodiversity

What is the role of coloration in beetles as per the example given?

• It is purely decorative

• It helps in camouflage from predators

• It has no evolutionary significance

• It is a result of artificial selection

What is an example of a vestigial structure in humans?

• The heart

• The appendix

• The lungs

• The brain

What is the significance of geographic isolation in evolution?

• It prevents species from evolving

• It leads to diversification

• It causes species to become extinct

• It has no effect on species

What is the process called when a single ancestral species diversifies into multiple species?

• Genetic drift

• Adaptive radiation

• Natural selection

• Artificial selection

What do homologous structures share despite having different functions?

• Different evolutionary origins

• Similar bone structures

• Different genetic codes

• Similar functions

What is the role of environmental pressures in the diversification of species?

• They prevent diversification

• They drive diversification

• They have no impact

• They reverse diversification

What is the significance of adaptive radiation in evolution?

• It leads to the extinction of species

• It results in the formation of new species

• It prevents species from evolving

• It has no impact on species
