Question

How are fossils useful to us in learning about our ancestors

Answer 1

Fossils are the preserved remains of ancient organisms. Animal fossils include:

actual parts of the body, such as bones or an entire skeleton;traces left by the body, such as a trail of footprints.

Harder tissues, such as bones and teeth become preserved as fossils more often than softer tissues. This is because softer tissues such as skin and flesh, are more likely to be eaten by animals or decay before they can be preserved.
