- Multiple ChoicePlease save your changes before editing any questions.The forelimbs of vertebrates, like the ones pictured here, are similar in terms of number of bones and the orientation of bones. Which best describes how comparing homologous structures provides evidence of evolution?The genes for the body plan and forelimb layout were present in a common ancestral species vertebrates share, thus passed onto all vertebrates.Similar anatomical structures show how animals adapt to changing environmentsHomologous structures show that different species evolve at different ratesHomologous structures don’t actually provide evidence for evolution
- Multiple ChoicePlease save your changes before editing any questions.A fossil of an extinct dinosaur is found and the anatomy of the fossil shows similarities to that of a bird. What could this mean?This is purely by chance and isn't significantThe extinct dinosaur and modern bird share a common ancestorAll dinosaurs evolved into birds and that's why there aren't any dinosaurs alive todayDinosaurs choose to fly, and evolved into birds to escape predation and capture food
