Which of the following statements about the fossil and living records of species are correct?
The combined record of living species and fossil species is essential for understanding evolution. - Fossils may be the only source of information about some extinct species. The two sources of information need to be combined to have a more complete picture.
Living species provide an incomplete picture of evolution because only surviving lineages are represented. - Only a fraction of the many species that have existed are represented among living forms.
Nearly all of the fossil species one might find are also represented by living forms. - Many ancient species are now extinct.
Species represented only as fossils are best ignored because information about them is incomplete. - If we ignore fossils, we will miss a lot of important information about the past.
