Question

Which of the following describes fossil evidence that supports biological evolution?

Fossils of an unknown species found in isolation from any other species
Fossils of an unknown species that is an intermediate form of two other species
Fossils of different species found within the same geographic area
Fossils of the same species found in a variety of geographic regions

Answer 1

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 of present-day species.
