Explanation:
1. Human and apes are evolutionarily closely related based on the analysis of their DNA sequences.
2. Wings of bats and birds serve the same function and are analogous structure.
3. Comparative anatomy is the study of the similarities and differences in structures in similar species.
4. Fossils demonstrate that during the evolution of the whale, the whale moved from land to the sea.
5. The human tailbone and appendix are vestigial organs.
6. The homologous structures are structures that are similar in related organisms because they were inherited from the common ancestor.
7. Comparative embryology is the study of similarities and differences in the embryo of different species.
8. The forelimb of all the mammals has basic bone structure.
9. Scientists who find and study fossils are called paleontologists.
The type of soil that has the least amount of space between the particles is clay.
