Question
Match each description or example with the type of evidence it provides to support the idea that living organisms evolve.
1. The skeletons of mammals that existed 150 million years ago are different from the skeletons of mammals that exist today. (choose one) (Fossil record, Molecular evidence, Comparative anatomy)
2. The front limbs of humans, bats, birds, and whales all have a similar bone structure.(choose one) (Comparative anatomy,Molecular evidence,Fossil record)
3. All vertebrates contain the protein hemoglobin, but the structure of the hemoglobin molecule varies from one species to the next. (choose one) (Fossil record,Comparative anatomy,Molecular evidence)
Explanation / Answer
1. Fossil record- Fossils skeletons of mammals long ago are compared to the skeletons of mammals today. 2. comparative anatomy- Animals limbs are compared and are derived from a common ancestor, yet have evolved different functions over time. 3. Molecular evidence- Hemoglobin is common to all vertebrates, but this molecule has evolved and differentiated throughout history among different species.
