LIFE SCIENCE

Detailed explanation-1: -Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record.

Detailed explanation-2: -The fossil record provides snapshots of the past which, when assembled, illustrate a panorama of evolutionary change over the past 3.5 billion years. The picture may be smudged in places and has bits missing, but fossil evidence clearly shows that life is very, very old and has changed over time through evolution.

Detailed explanation-3: -Explanation: By looking at fossils, one is able analyze the physical structures of past organisms, many which have since gone extinct. You are able to see how old these organisms were/what eras they lived in by using relative dating.

Detailed explanation-4: -Trace fossils are rocks that have preserved evidence of biological activity. They are not fossilized remains, just the traces of organisms. The imprint of an ancient leaf or footprint is a trace fossil.
