- Q1What is the theory of evolution?The idea that evolution is a debate.The idea that all organisms are the same.The idea that gene distribution changes over time.The idea that evolution is random.30s
- Q2What do fossils teach us about evolution?Fossils show how organisms have changed over time and how new kinds of organisms originated.Fossils show that organisms never change.Fossils show that evolution is random.Fossils prove that all organisms are the same.30s
- Q3What do homologous structures suggest about organisms?Homologous structures suggest that organisms are related and descended from a common ancestor.Homologous structures suggest that organisms are not related.Homologous structures suggest that organisms are from different planets.Homologous structures suggest that organisms are created independently.30s
- Q4What does DNA sequencing reveal about species?DNA sequencing shows that species are not related.DNA sequencing shows how closely related species are based on the similarity of DNA sequences.DNA sequencing shows that species have different DNA.DNA sequencing shows that species have no similarities.30s
- Q5How does biogeography support the theory of evolution?Biogeography explains the distribution of species based on evolutionary history and geographical change.Biogeography suggests that species do not adapt to their environment.Biogeography proves that species are randomly distributed.Biogeography shows that species do not change over time.30s
- Q6What is microevolution?Microevolution is small-scale changes in allele frequencies within a population over a short time period.Microevolution is rapid evolution of new species.Microevolution is large-scale changes in allele frequencies.Microevolution is evolution that only occurs in plants.30s
- Q7What is macroevolution?Macroevolution is long-term, large-scale evolutionary changes that result in the formation of new species.Macroevolution is limited to only certain groups of organisms.Macroevolution is unrelated to the formation of new species.Macroevolution is short-term, small-scale changes in allele frequencies.30s
- Q8How does the theory of evolution explain the diversity of life on Earth?The theory of evolution explains that organisms adapt to their environment and diversify over time through genetic changes.The theory of evolution explains that diversity is random.The theory of evolution cannot explain the diversity of life.The theory of evolution explains that all organisms are the same.30s
- Q9What is the relationship between DNA and evolutionary relationships?DNA sequences are unique to each species.DNA has no relationship to evolutionary relationships.DNA sequences can reveal the evolutionary relationships between different species based on shared genetic information.DNA sequences are not related to evolutionary history.30s
- Q10How do geographical barriers contribute to evolution?Geographical barriers have no impact on evolution.Geographical barriers can isolate populations, leading to divergent evolution and the formation of new species.Geographical barriers cause all species to become the same.Geographical barriers prevent evolution from occurring.30s
- Q11Why is the theory of evolution considered a scientific theory?The theory of evolution is considered a scientific theory because it explains a wide range of observations and is supported by empirical evidence.The theory of evolution is based on random ideas.The theory of evolution is a hypothesis, not a theory.The theory of evolution is not considered a scientific theory.30s
