- Multiple ChoicePlease save your changes before editing any questions.How do fossils provide evidence that evolution has happened on Earth?Fossils show how the sizes of certain animals has changed drastically over millions of yearsFossils show that some species have gone extinctFossils show how life forms present today are different than those from the pastDifferent sedimentary rock layers provide evidence for how the environment has changed over time
- 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

Which field of study would support the similarities in development as evidence for evolution?comparative biochemistrypaleontologycomparative biogeographycomparative embryology
- Multiple ChoicePlease save your changes before editing any questions.What do scientists generally find when comparing the relationship of living things in different geographic areas?Species living further apart geographically typically share a more recent common ancestral species than those living closer togetherSpecies living closer geographically typically share a more recent common ancestral species than those living further apartThe location of where an organism lives gives no insight into their evolutionary relationships to other speciesTheir protein sequences depend on the protein intake from the local watering hole.
