Question

Choose the correct answers from the alternatives given .
The fossil record offers direct evidence for common descent because you can

• A. Sometimes find common ancestors
• B. Trace the ancestry of a particular group
• C. See that the types of fossils change over time
• D. All of these

Answer 1

The correct option is D All of these

Fossils are the preserved remains of previously living organisms or their traces, dating from the distant past. Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet's history. They can also help scientists reconstruct the evolutionary histories and ancestry of present-day species. For instance, some of the best-studied fossils are of the horse lineage. Using these fossils, scientists have been able to reconstruct a large, branching "family tree" for horses and their now-extinct relatives.

So, the correct option is 'All of the above'.
