ANATOMY

Detailed explanation-1: -D. fossil record. 5. Which word is defined as the same structure in different species indicating a common ancestor?

Detailed explanation-2: -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-3: -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-4: -Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation. Key points: Evidence for evolution comes from many different areas of biology: Anatomy.

Detailed explanation-5: -Often, fossil species first appear in older rocks and disappear in younger rocks, providing evidence that species change. Changes in climate, indicated by geology, correlate with changes in fossil species and their adaptations, supporting the idea of natural selection.
